DistantTea said:Yeah the mazdaspeed is a great D stock car, but it has limitations that make it not as fun on the street as some other cars. Plus you gotta beat a Type R whenever you can.
So here's the idea. What would it take to make the perfect STX legal autocross mazdaspeed? Parts have to actually exist and links to those parts would be great.
The STX national champion car last year was a 220HP+ Integra Type R. To beat it the mazdaspeed has to up the ante within the STX rules. A short list of rules can be found at www.moutons.org if you aren't familiar.
I could be wrong but I think we're aiming at 200HP with an emphasis on torque and engine response to beat the Type R where it is the weakest... low end grunt. We also need to lose at least 200 lbs from the car. Things like CF hood are legal... so lets see what we can save.
So lets see what we can come up with... money is not an object... but the rules are.

I would expect there is a Koni SA setup out there with ground control springs that will do very nicely for under $1000...

You may not need to go all the way to the Koni 28xx series, but for a serious ST/SP suspension setup you're going to want double adjustability so you can change the compression rate when you change spring rates, and you're going to want a durable shock. Candidates include the Koni 30xx series, Penske DA, JRZ, Moton, and Advance Design. The latter are the cheapest way to get a "high-end" monotube double adjustable shock, but you'll probably be entirely on your own for figuring out the proper settings and adjustment ranges. Each of the others, depending on where you live, may have a local expert who can help you figure out where you need to go next, and maybe even show up at events to watch, ride, or even drive your car to see what it's really doing. That kind of help is crucial for stock class shock tuning, because it's such a strange art to tune a car's behavior without being allowed to touch the springs. It may be less so in ST/SP, since suspension tuning in those classes is closer to the theoretical ideal: use the springs to adjust handling response/balance, and just use the shocks to keep the springs from oscillating, and a little bit of fine tuning.
I wonder if the Bilstein inserts in the ADR strut kits can be converted to adjustable. It's probably around $150/shock to do the conversion, but Bilsteins are rebuildable and revalvable, and the quality is there...just another option to consider.

i *highly* recommend the H&R camber bolts. the model for us is TC112.
there has been a lot of discussion of the ST tire situation on sccaforums. don't forget about the new hankooks (225/45/16!), the falken 451s (when shaved, and lots of good sizes), and the toyo T1-R ($$$$, but lots of great sizes coming). don't discount the "old" azenis either.
