2019 SCCA Solo National Championship - F Street Recap


Reflecting on any national championship campaign is a year long process full of what-ifs, laughs and (sometimes) tears. 2019 was arguably one of my greatest nationals experiences to date. This was my 11th Solo Nationals, 8th trophy finish, 4th Third Place finish and the 2nd time co-driving with Alex Kang













If you didn't know already, the SSM RX7 engine failed this summer conceding its contention at the big show. Alex and I were very much looking forward to the wild ride of the fire breathing turbo rotary but when the writing was on the wall we quickly transitioned to #PlanB. Fortunately, in the #garage lay this beautiful #E92 #BMW Lime Rock Park Edition #M3that slots perfectly into F Street class competition. With only one local autocross left before the car needed to depart for Lincoln, I jumped at the opportunity to race with @motorsports_northeast to reacquaint with the car. Before that day, I'd only autocrossed about 10 runs in the car much earlier in the season. Plan B, which was a premeditated contingency, also involved mounting up the fresh set of Bridgestone RE71R tires that were waiting in the garage - a decision which would later prove questionable.
Alex and I would arrive in Lincoln in time for the ProSolo Finale and compete in our respective classes, ES and S1 (not in the M3). After the fun drive in Erik Strelnieks Acura NSX at the ProSolo Finale where I’d finished DFL - not a huge confidence boost - Alex and I jumped into our BMW chariot on the Nationals Test and Tune course. There we dialed up the front sway bar and raised tire pressures until the car felt fast, balanced and ready for the big show.
Day one of competition rolled in with gorgeous sunny weather on the very fun east course. We shared the grid with countless BMW M3s and a few American pony cars, all of which were sporting #V8 power. The competition featured reigning 2018 Champion Jeff Cashmore and Tony Chow and Tom Layton - both of whom placed 1st and 2nd earlier this season at the Fingerlakes National Tour ahead of me in the Lime Rock M3. On my first run I over drove several sweepers finding the visuals for judging the room on corner exit very tricky. Tony in the #84 car set fast time by a considerable margin, 0.8 faster than the second place car and 1.3 ahead of my time. It wasn’t until I was released for my second run behind Tony’s co-driver, #184 Ido Waksman, did I realize they were sole FS car campaigning on the new Yokohama Advan A052. Recalling how earlier that day the leader board for STR showed the entire trophy line up was on the magical Yoks, I had considered in that moment perhaps we’d made the wrong tire selection! Quickly I shook off that thought and inched forward to the starting line focusing on the course. I screamed “LOOK AHEAD!!!” - my regular pre-run mantra - and launched ahead. I had significantly improved my car placement on the second run but sadly the time was negligibly slower than my first pass. I must have underdriven the car. Alex and I did some minor tire pressure changes for final runs but generally left the car alone for the third runs. On the third and final runs, I was able to combine great car placement with speed and aggression, squeaking out another half second improvement, while admittedly leaving some time on the table.

After day one runs were a wrap, I’d convince myself there was more time to be had on Yoks than Stones. The search for new tires began. A short phone call to Tire Rack made it apparent the tire was in short supply. A distress call was released on social media to source a set of magic sticky donuts. Simultaneously, Alex and I cruised paddock identifying most of the Yoks on site noting sizes and quantities. Not long after that, word came through friends on site and social media that Dennis Barrett’s broken RX8 was sitting on Yokohama A052s in the exact same size as the #84/184 M3 and Dennis was willing to part with them. The transaction was consummated first thing Day 2. By 9:30am they were mounted and balance on our competition wheels thanks to the onsite Hoosier Tire service vendor.

Running last heat, we’d spent the better part of the day speculating and second guessing whether we made the right call. The way we saw it, the tire is unlikely to be slower than the Stones and if they were in fact faster, we potentially put ourselves in contention to snipe the championship out from under Chow, should he happen to cone out all three runs (or generally underperform).
At the start of the fifth and final heat, we couldn’t help but laugh at ourselves for bringing the car to grid on the Yoks - our hail mary attempt at a 2019 F Street championship! Now, we just needed to drive fast and hard to make the dream a reality. Alex would be first out of the gate. He quickly and enthusiastically returned to grid shouting the trademark-Alex catch phrase, “These are WAY better!” Feeling confident but inexperienced, I’d underdrive the first few elements on my first run before realizing the Yoks full potential. By second and third runs I dropped 0.7 and 0.5 respectively for a best pass of 66.5. Tony Chow would claim his first national championship in F Street with excellent driving both days and a two day margin of victory of 1.0sec. His day two time posted a 66.2 which was much tighter to my best run and Jeff Cashmore’s 66.4.

By the end of the day Thornes good buddy Chris Mayfield swooped up my Yoks. By 5pm they were sold and on Mayfields car making my car the world record holder for shortest ownership of Yokohama Tires at 7 hours and change. Chris would go on to win the STU championship on them in his E92 M3.
Were the Yoks truly faster or was the Yokohama grip sensation a glorified placebo effect? Who knows, but it was fun to pull off the hail mary attempt and hammer down a fast lap in the hunt day two.

Thank You:

Thank you Alex for all your support, especially when my knee gave out and you made a midnight run to the pharmacy for a brace. Alex is one of the most enthusiastic, positive, energetic, accommodative and fun co-drivers anyone could ask for. Thank you to Robert and Amanda Thornefor helping with the logistics, hospitality & race prep and congrats to you both on your 2019 jackets. Thank you to the family for always rooting for me and supporting the campaign for the weeks leading up to nationals and for the entire week I disappeared to the middle of the country for this silly race. I love you all! Thanks to Dennis Barrett for letting me poach your tires while your car was injured, I am sorry your STX RX8 nationals campaign ended early. Thanks to the SCCA & The City of Lincoln for hosting all of us coneheads. Thanks Erik Strelsnik for the surreal ProSolo Finale ride - an NSX on Hoosiers. Thanks to all the 2019 F Street competitors for the awesome race and keeping us on our toes. Thanks to all our marketing partners including HGU NYC: A New York Hotel (www.hgunyc.com), Jaxe & Company, Alfa Development, Bridgestone, Hawk Performance & Tire Rack. I will see you all in 2020.

"The One-Wheeler-Peeler", part 1


By: David Corsaro

Well, the Evo X was sold back in November to make way for an even more potent vehicle... a 2012 Toyota Yaris! 


Okay not entirely true- the Yaris is a tad slower and it wasn't meant to replace the Evo. 
This five door dorkfest is my daily driver. 

Being the SE version, it gets a good number of upgrades over a base Yaris including four wheel disc brakes, a quicker steering rack, and 16" alloys for starters.  I also topped out at over 41mpg driving to Lincoln last year... on Dunlop Star Specs. 

 


But can it be fun to drive? Yeah, but not without tinkering.

The first modifications were Tokico HTS shocks and struts and an Ultra Racing 23mm rear bar to help restrict the rear torsion beam from twisting. Crash bolts were added to the front struts for extra negative camber.

Almost on two wheels... let's see if I can keep it on the ground this year.
Adding the ever-proven Dunlop Z1 Star Specs in 205/50/16 on the stock 16" x 6" wheels provided much needed grip over the stock tires. 

Just these few simple changes helped the Yaris nip at the heels of a couple of very well-driven Minis at our local autocross... 0.5 to 1 second behind on a 60 second course. 

Close, but still an eternity in autocross terms.

Clearly the Yaris' biggest flaws are large amounts of body roll coupled with an open front differential. To be fast with these cars will require maintaining momentum, increasing composure and avoid spinning the inside front tire which just wastes energy and adds seconds. To do all of this however requires modifications that will bump the Yaris to one of the newest classes in SCCA's Solo program- Street Touring FWD. 

While still only a supplemental class, it has seen moderate support at the national level and a little better support at the regional level. The majority of experienced autocrossers prefer to drive vehicles that are proven winners in their respective classes. There are a few exceptions, those willing to drive cars that are considered shitboxes within the sport. I am one of those exceptions because I will race anything... but it should be fun to drive too. 

The most difficult task in preparing a vehicle for double duty is keeping a streetable ride for commuting during the week while having a competitive car for the weekend.

Having run Star Specs on five different cars since 2008, I have decided to go with Dunlop's newest creation, the ZII. I am going to start the year on shaved 225/45/16 for the fronts and will be using up my old shaved Z1s in 205/50/16 out back.
Like the Z1, the ZII maintains the ability to flipped inside to outside and consequently LF to RF, LR to RR... rewarding competitors with longer tire life. Less siping on the outer treadblocks should lead to higher grip levels than the Z1.


Ever since owning a Championship White 1998 Integra Type R several years ago, I have always had a soft spot for white cars on white wheels. Can't wait to see them on the car!

The wheels are Kosei K4Rs that I had powdercoated, in size 16" x 7.5" for the fronts, 16" x 6.5" for the rear. 
They weigh in at 13.6 lbs and 12.8 lbs respectively.

The idea behind the heavy stagger is that I did not need, or want, as much grip in the rear as it would be counter-productive in really getting this car turned in and exiting out as efficiently as possible.

 Here is what will tie it all together, literally. Cusco's trick aluminum strut tops(right) with integrated bearing and Whiteline's front control arm bushings(left).

The OEM upper strut bearing on the Yaris uses a pathetic 'bobble' strut top design, meaning that a spongy rubber-isolated bearing is merely sitting into a cup from beneath the chassis. 

Hit a bump, and the car virtually unloads itself off of the bearing since it is not in any way fastened to the car. 

Dive hard into a corner? Mush-fest, camber-loss city. 

The design of the Cuscos fasten the top of the strut to the vehicle's chassis. This will not only allow the springs and struts to do their job as God intended by it will also help maintain front camber a shit-ton better. 

Whiteline's inner bushings for the front control arm will help maintain toe settings as well as caster/camber to an extent. 


The polyurethane control arm bushings also have a side-benefit of controlling wheel hop. This is a big problem for most front-wheel-drive cars with sticky tires. 

I have already started to tackle the chore of locking down the front end by installing custom delrin inserts I fabbed up for the engine and transmission mounts seen above and on the left.

The passenger side mount(not pictured) is now solid steel. 



Next up on the list was probably the most surprising of all... aluminum pulleys. Upon receiving them I verified their total weight at 22.675 oz total. Pretty damn light. 
The steel OEM pulleys weighed in at a shade over 68 oz, so a total savings of over 45 oz or just under 3lbs. My highly calibrated butt dyno witnessed quicker acceleration from a stop and better pull in gear at low rpms. Well worth the money and time to install.

Crankshaft, water pump and alternator pulleys from NST.

In the coming weeks, I'll be continuing to remove weight legally from all areas of the car on the cheap. I have yet to share what I've done for springs and roll control but I am pretty close to getting the suspension to where I want it to be, and while it is a little unorthodox, I feel that it is capable. Think NASCAR or dirt track hillbilly stuff. 

To be continued...

Hamfist Racing SSM RX7 Wins Toledo ProSolo & Takes Atlantic Zone Championship! Next Stop Nebraska...

At the Toledo Express Airport traction was high but emotions were even higher. After years of preparation, the Hamfist Racing Super Street Modified (SSM) RX7 was ready to be pitted against the High Pressure Performance RX7 of the Thompson family at the 2012 Toledo ProSolo. Many believe the Thompson's RX7 is the most highly developed SSM car in the country. They would be right to think so. Their RX7 had been dominating SSM competition across the country during the 2012 Solo National Tour and ProSolo series. Carter Thompson has tallied multiple wins over Erik Strelnieks' 3-Rotor, three time SSM national championship, Jungle Cat Racing RX7. With Carter's track record, my goal going into the event was to just keep up. The anxiety reached a paramount as SSM drivers approached the start line for competition Friday. I was excited, yet fearful, to see how the car would shake out in comparison to the Thompsons' creation.

High Pressure Performance SSM Mazda RX7
At the start of competition Friday, adrenaline built up so strongly in my body that I proceeded to jump the lights and get disqualified for three of my four runs, putting the car in last place. The raw times were suppressed in the results, which merely displayed "RL" indicating the disqualification from a red-light start.

The next morning the competitors conceded they dug through the raw data online and found my times were at the top of the class. My confidence was buoyed by my scratch time performance from the previous day. With dwindling anxiety and increased familiarity with the start line traction, I was able to blast out of the hole with green lights laying down lap after lap of blisteringly fast times. One lap, most notably, was into the 26.XXX second realm which raised eyebrows across the event. This performance on day two posted me solidly in first place over Carter Thompson, Brian Johns (former ES National Champion), and Dan Chadwick (RX7 guru and 2009 SSM National Champion).
Charles Berger
The day was a success but tomorrow I would need to improve lap times further to lock in the win. Later that afternoon I received a call from my family with heart sinking news that my grandfather passed away. He led a long life, raised a great family - including my mom and two twin aunts - and pursued his dream, successfully becoming a professional artist and illustrator. I will miss him and my grandmother greatly.

For most of the weekend, I was able to keep my family in my thoughts. However any autocross racer can tell you, the moment the clutch is released going into a sea of cones, there is only one clear and concise goal dominating every action in your body and ounce of concentration in your mind. That goal is driving perfection. It is this surreal experience of absolute concentration and physical precision that motivates racers to continue in this sport. Life may be scary, sad or confusing at times. For a racer, driving is an escape, a meditation, a moment of clarity.

At the starting line Sunday for final SSM class competition runs, the tree began flashing... Yellow. Yellow. With that second yellow flash of light, my minded raced with compassion and grief towards the loss and pain in my family. Yellow. By the third and final yellow my mind went completely blank. My right foot pushed the gas pedal to the floor-pan and my left foot lifted off the clutch towards to the sky! The rotary powered Mazda tore off the starting line with the fury and power of my entire emotional state. I was able to pull off the ultimate class win with dueling 26 second lap times on both left and right courses.

Below is the uStream video from Sunday Heat 3 competition runs. The action between Carter and I begins at the 1:25:00 mark

Tri-Point Engineering Front Sway Bar and Video's from NYR SCCA

The new Tri-Point Engineering front sway bar was installed on the Hamfist Racing SSM Mazda RX7. The bar was set to full stiff to try and settle the rear end of the car, which has plagued the RX7 with tail happy unpredictability since the front tire size was augmented to 315/30/18. First impression: The car seems to have worked well. The front body roll was significantly reduced yet the car pivots on turn in very sharply. The car took FTD overall 93 drivers at the July 7th 2012 Solo race event at the Nassau Coliseum. The fastest lap was a 52.9XX second lap. Here are a couple of videos from the morning heat runs (not the fastest lap). The surface was full of rocks and gravel. Warning, this video contains adult language, a terrible camera mount, a dirty rear windshield and dismal 1htz sampling rate for the GPS. Parental consent is advised. Enjoy.
