I have a 2000 4dr gsr...I am competing in the STS class, in San Diego. I have only done three events but I love it. the car does very well in this class, so far, and i havent even done the recommened mods yet. So far i have h/i/e, and heavy 17"wheels w/ very hard compound tires 340 treadwear, and i was within 1.5-3.5 seconds off the top guys. But i am in the process of doing the suspension and a few other things, which should drop my times by atleast 2 seconds, then its all about seat time. Helping me with my setup is a guy who in my region is considered the "King of FWD" he has owned a couple of integ's and know the hot setup...the total amount you need to spend is approx. $5000 thats including wheels and tires. If you want to know more let me know and i will give you the info on what to get and from where. Good Luck!
