What setup does everyone in B-stock favor?Tire size, shocks, sway bar?
What setup is everyone running as far as tire size, front bar and shocks. Just trying to get a feel for what most are running before i change the car any more than it already is.
So far i have run with two different setups
1. completely stock other than alignment and 285 kumhos
2. drilled front bar, front koni yellow(waiting on rears) and 285 kumhos

Stiff enough shocks to help out the weak axx springs, fresh Kumhos or Hoosiers (any size that fits the 8" rim) and an alignment...that's enough to bring it all down to driver inputs. The RX8 is set up agnostic in stock class. 
...and I'm only partially kidding. I've driven Sipe's, Isley's, Caulson's, Jones', Goeke's, my own and a few more than I've forgotten about...they are within a pretty narrow bandwidth, imho, with most of the noise being the relationship between front bar used and alignment.

I was just curious what tires most people favor. I found a stupid cheap deal on 295 ho ho's. and was looking for feedback. I have a set of 285 ho hos that im trying next and also have 245 hohos and kumhos at my disposal

The 295 works very well, but there is a gearing disadvantage on the torqueless RX8 with the increased height.

Solo,
have you tried any of the other tire sizes on your car or did you go straight to 255's

In the press release (see 11/10/08 release) that Hoosier put out, Hoosier states the new 255/35-18 size was made for the RX8 with 8" wheels.
Btw, GRM articles FTW!!!

Solo,
I did just rear that article in grass roots and though it was very interesting. I definitely think that once its time to actually buy a new set of tires i will go that route. So far i have tried the 285 kumho only, i have another local in 2 weeks that i will be trying some 285 hoosiers on the set of ultraleggera's that i just picked up from georgeh. I should also have my rear koni's back today and that will another piece to the puzzle. Ill let you guys know how the car feels after that.
Sacha

Woody (John Rogers) and I have continued to experiment with set-up and the 255's over the Spring. We have run several events with 285 fronts and 255 rears and finally corded our first 255 after approximately 80 runs. (One flip, 80% on the rear of the car). We went back to the 285 fronts primarily for the tread wear advantage and the small amount of mid-corner out grip advantage we noticed in the test. The downside is slightly less precision through transitions as we noted in the GRM article.
IMHO - The "fastest tire" still comes down to driver preference (confidence) and the course design on a given day, highly transitional courses will favor the narrower tires, big sweeps lean toward the wider tires. 245/255/285/295 are ultimately very, very close in performance on the RX8.

Chike,
Not this year, the last time I was out there was in 2006 when my co-driver(greg hahn) and i both trophied in astock in my s2000. Plans are to run some national events and nationals in 2010
Chris,
I think ultimately you hit the nail on the head. I think it depends on driver preference and driving style. Most people who like the crisper turn in will like the smaller tire, while those of us who arent quite so smooth will prefer the larger tire. The 09 with the different gearing changes things a bit as well
dmitrik4,
the motons are legal as long as they are setup properly. Solo can comment a bit more but from what i understand its the same issue that us koni users are having which has to do with the rear perch height being different on the 09

Not to derail... However, if I didn't worry about staying in B Stock, would it be advisable to replace the springs? If so, should I pursue a particular brand?
I've been autocrossing my mostly stock RX8 for about 18 months. I run street tires only on 17x8 wheels. I plan on getting Koni Sports soon plus the Progress Technology sway bar, but was on the fence about springs. Also, note that I mostly run on relatively grippy concrete.

Btw, the group buy thread is in this Competition section of the forum, but lower down the page. So as to not derail this thread, maybe post questions in there.

Are the Motons legal in Stock? I thought I read that they weren't (although what I read wasn't clear as to why).

In addition you can't cut any metal to get access to the rear shock top rebound adjustment. So Bill of Small Fountain Racing made up adjuster cables so I can adjust rebound.
you can cut metal for the remote reservoir hose, but not for shock adjusters, the shock adjuster mods are limited to interior trim panels only i.e. the cosmetic trunk side covers, but not the metal chassis, we just discussed this in another thread recently
