well---i dont know that the eight would be such a push over on the corner exits either if you drop the gearing a little with 17" wheels and a 40 sidewall tire. Believe me it does change the character of the car on corner exit. recently a s2 and oldrer model track prepared 3 series DID NOT PULL ME ON THE STRAIGHTS. I have the midpipe, RB intake, underdrive pulley(mostly for temp control)--new coils and plugs and was running 1 oz of pre mix per gallon. True it may have been the driver--but road atlanta has a long back straight and it was consistant. This engine has a lot of rpm but the powerband is not as wide as some may think. So gearing is of great importance.
one thing about the hoosiers is that they do run wide--so for ttd get the autocross hoosier(A6) in a 235 sized and that should be enough. TA was running on second hand RA's---you go dude!
lot of other stuff could be talked about.

All too close. The trainers for the dealer techs called it the Hubble when it came out, because it was launched and put out there, and then had to get fixed again and again.
Mine has most of the standard problems. But 80 percent of them stop being problems when you finally accept that the car is a track **** and allow yourself to only care about passing the 50/50 rule.
Okay, I'll shut up about this car on this forum now. Sorry for the OT.

I know the RPO3 will clear the Sport brakes, SilverEIGHT has a set of those, and they cleared fine. He has them for sale now. OD has the RPO1 in a 17", and it also clears OK. The Enkei RSM or something like that, does not clear. Not all 17's will. As mentioned, discuss it with people who have winter wheels in that size. Your problem will be, not all of those will be much lighter than stock, since their purpose is more utilitarian. That is why I mentioned the Enkei's that I know will fit.

Just finished up my first weekend running with NASA. I must say it was a very well run event. Got some great instruction, met some really great people, got a TON of track time, had absolutely fantastic weather all weekend and had a lot of fun.
I think we also got another member hooked.
And to anyone who hasn't been there Gingerman is a great track.

I currently am in the "tires are everything" camp so I run Hoosiers but right now it is a lot of $ and I am running virtually a stock setup compared to guys like those "pictures" which are well modified. I am now keeping up to these guys.
Any thoughts?

Is it better then to give up some grip for say suspension items? I am struggling to find items that make "noticeable" power and that are of any value ($/performance)?

Suspension wise get the fatest sway bars you can. They are only 2 points and you will corner flat, which will allow you to dial in a ton more camber and corner harder.

Unless your rules forbid spring changes, this sounds like overly simplistic advice. There's a "right" sway bar stiffness which varies based on your spring rates and other setup. You don't see F1 cars running the fattest sway bars they can -- they use the right bar for the situation, and you should as well.

we changed to a road race spring setup (800/400) after Packwood on on the STU car and tested between the stiff and soft bars. The stiff bars (Progress Technology, stiffest bars available for the RX-8) were faster and felt better even on street tires and the HPT Nats surface. I was sort of surprised, my anticipation is that the softer bars would allow the car to be faster in the turns and hook up better accelerating out, but the opposite actually occurred.

thing about a hoosier is that you can run a 225/45-17 which is good for the points(size wise) but the hoosier always run wide so the actual size is not a true 225.
Mine was $200 for the set so they were hard to turn down.
On Mods---get the brakes to the best you can--with the 8 this is one way to make time.
Sways? Dont forget the endlinks. Stocks have been known to bend.
Definity go with a 17" wheel.

Have to strongly disagree. I'm running the stiffest RX-8 bars out there; 1.25" OD x 0.25 wall front and 3/4" solid rear, using OE endlinks without issue.
Only people I know who had an OE endlink issue did so because they installed the rear bar upsde down, which causes it to hit the subframe

What did you do to the brakes to improve?
I am using the Mazdaspeed anti-sways (F & R). Would I do that much better w something else?
I know the Eibach's I use are way soft and that I would really need to do the following:
1) backoff on the Hoosiers and go to a lesser tire - ex. Toyo's
2) replace Eibach spring with something stiffer and change OEM shock to _______
3) go from 18" to 17" wheels
4) ??

I've been following your threads about the 17" wheel and change in "gearing" it provides....sounds interesting to try.

The greatest upgrade you can do for the breaks is upgrade the pad compound. Lots of people around here use the Carbotech XP-8 compound as a track day pad.

how many track days are you getting out of a set of XP-8's, and are the track brake intensive? I just bought another set of HP+, and will see how long they last with my new found use of the brake pedal. I am just curious to see if the added cost of the XP-8's offset them lasting longer. TIA.
