We take a lesson from the Koni Challenge and development done on Mark Sipes' SCCA Solo STU classed RX-8s and the corner attitude flattens.

From the before and after pictures on the left it's obvious that the upgrade works to keep body roll in check.

Much thanks to Mark for his consulting and Anthony Zwain of Edge Motorworks/Speed Trapp Racing for installation and tuning assistance.  Also thanks to Matt Mederios for hooking us up.

Attitude, it's improved with roll resistance!
IMPROVED ATTITUDE???  We'd say so!

Not only does the car corner a lot flatter, it remains very civilized on the street on all but the sharpest bumps.  The tramlining produced on the stock springs with the enormous 285/30 x 18 competition tires is all but gone, again, making it a pleasure to drive with rear seat passengers between events.

As for competition, while Mark Sipes proved that an RX-8 was slightly off the National level pace of the Evo and STi rally cars in SCCA Solo STU trim, it's certainly not an embarrassment on a local level. 

Sans a good shakedown or even being raised to recommended ride height and corner weighted, the setup proved quick in the hands of Rick Gould, Mark Scroggs and RX-8 B-Stock driver Matt Francavilla.  During fun runs at an SFR event they were able to lay down times that beat both the Class winning STU STi and B-Stock RX-8, that with us also being being hampered with undersized (245/40 x 18) year and a half old street tires.

One wonders just how quick this setup would be on a set of proper competition tires, say 285-295 A or R6s.

Racin's Rubbin'

We're sure you've heard the saying; "Racin's rubbin'.".  But we don't think they were talkin' about their tires against their fenders (that'd mean a pit stop). 

We've added Tokico D-Specs since the Corkscrew pictures and can get another half a degree of camber but will it be enough to handle the fat wheels and tires?

Do you see the camber gain on compression in the pics below or is it just wishful thinking?

All the pics enlarge when clicked, just in case you want a closer look.

We're no longer afraid of the Monster!

With a competition alignment we don't rub, not even across the "woop-de-wooes" of Monster Park, Candlestick Point.  Of course, Halloween's on it's way and some fast guys moving to BS RX-8s for SRF SCCA Solo Slush series.

Absolutely incredible,

the V710 285/30x18s transformed this RX-8 from great to an incredible street car.


Running the car for testing purposes in B Stock (fun run) at SFR SCCA Solo's Championship Round 15 we had one of the class leading Super Stock Z06s wondering about our setup when our first run, scratch, was a half a second quicker than his. At the end of the day, results posted, our best time, if it had counted and it had been clean, would of PAXed first, sixth Over All in 186 competitors finishing in between a Factory Five Cobra and a SM2 Miata.


Yes, we know, could've, would've, should've and “frogs wouldn't bump their butts getting from place to place, if only they had wings”, yadde, yadda, blah, blah, whateva, but the point is that the big tires transformed the car. 


Confident that the V710s wouldn't self destruct against suspension or bodywork we moved on to Thunderhill Raceway Park's 3 miles of 36 foot wide FIA Standard pavement and the results were, again, incredible. Without lap timers it's difficult to quantify but we were able to keep up with the Z06 of Gary McDaniel, a track day junkie and experienced autocrosser. Not only did the tires work for me, they did for Gary as well, pushing us both to the limit for the 20 minute session, separated only briefly by occasional lap traffic. The Z06 would pull the RX-8 on the long straights, the RX-8 would close under braking and we'd hang through the twisties.  Please check back for the video.

So, how do you go about getting this kind of a contact patch working on the stock 8” wide wheels?  Wish we knew!
