what classes
 

What classes are the RX-8 eligible for? BS SM STX or U?

BS and STU are for sure. BSP and SM the car fits but as far as I know is not listed there yet.

Anyone running STU nationally next year?? I know there are a few guys on the forum already running there regionally, but from the parts appearing in the marketplace it would appear that there are others plotting an assault on the stevos...

What would it take to prep an RX-8 for STU. I have been running an MR2 Spyder in CS and want to get away from changing tires 2x every event. Thanks in advance...

bs - yes
sts - no?
sts2 - no
stx - yes
stu - yes
bsp - yes
sm - yes
bp - yes?

why change the tires 2x every event? unless that is street -> race -> street. but that would be the same for any car (assuming the change to race tires).

STX - NO. It's specifically classed in STU.

The RX8 is all set for STU as is. Just add driver. ;)

Or:
17x9 or 17x9.5 lightweight wheels
Yokohama 255/40-17 Advan Neovas (excellent gearing advantage with fantastic grip)
Some kind of adjustable coilovers (ie: Koni double adjustables with ground control adjustable perches and 500-600lb spring rates)
Adjustable front and rear sway bars
Racing beat REV-I intake
Header
Exhaust with one highflow cat
Seats that weigh 15lbs.
Better rear limited slip.
Battery reloacted to trunk
AC removed
Some kind of engine management that would give a little more mid-range oomph.

That's about it.... other than good pads (do NOT need super duper calipers as then you're limited in wheel choice) something like Carbotech panther plus.

If I were building one... it'd look something like the above. ;)

Great to hear that!s

I guess some guys just like to lose. :hahano: You stick with those 225s. I would go for the 18X9.5" with a 275-35-18.

IMO those spring rates will never work on an RX-8 with street tires, you must have confused them from some other car

aftermarket/custom lower control arms may be required to, not sure if you can get the necessary camber range otherwise

These guys have setup a car: http://www.good-win-racing.com/ They had 18X9.5 all around with 275s under stock fenders. I don't think they have done much work in the power dept, just suspension. So far the car has not been that fast when I have seen it run, but I think that has more to do with the guy driving it than the parts on it.

OOPS! Typo fixed... should be 255/40-17. (Not 225)

Oh dear, where have *I* heard that before, where high spring rates won't work on a Double wishbone with streets.... Hmmm...

You can beleive what you want to... that's my story and I'm sticking to it. :)

As far as the camber range... I'm sure there's a way to add more camber without replacing a-arms...

Heck, even in stock form, the camber curve is excellent.. on streets without much grip and a high spring rate, you're not going to be needing much camber.

I'm not saying they aren't the right choice for some cars, only that I don't believe they are the right choice for the RX-8

as I recall, I also said I didn't believe the RB front swaybar would work on a Stock solo2 RX-8 either ... :wavey:

I've heard about these camber plates that are available...

:bling:

:ftw:

KC -- I understand the specific advantage or reason for most of these except moving the battery. Is it simply to balance weight??

Is a high-flow car allowed in STU?

oops - meant "cat" not "car"

yes, the exhaust system must be emissions compliant, otherwise you can change it entirely from header to outlet tip, including the cat converter.

you forgot under drive pulleys, and I hear those camber plates really stiffen the car :suspect:

So is anyone going to STU next year? KC?
