SCCA STR 370z Progress Thread.... It can be done!

Thanks for the info Mike and Mike! Could either of you post a link to the rear spring stuff you got? The Megan and other parts I find for the 370 all seem to want to work with their own wacky springs, not the normal 2.5" stuff.

For the Uprev, do I have to buy a copy? Or if I take my car to a tuner who already has the software, can he just use it on my car?

Since we have to run cats, is there much gain in catted longtube headers vs. stock manifolds + berk HFC? What's the best dynos you guys have seen of ~ST prep 370's?

For those not familiar with the ST rules, we are allowed to do:
Headers (but must maintain cats in roughly the stock location - cats can be aftermarket)
Cat-back exhaust
Cold air intake (up to throttle body, have to keep stock MAF sensors)
ECU tune (up to 100 octane fuel, no e85)
Crank and accessory pulleys
