I just did my first autocross in the GT3 this past Sunday (Fastest time of the three white ones mentioned above, although a very well driven and set up Honda took FTD). I don’t know about the Michelin Cups because my car came with Pirelli Corsas, but my experience is that this car wants to push in the slow corners and I actually ran higher front air pressures than rears (38 PSI front/36 PSI rear cold) and got about 3 pound pressure growth all around. My advice is to walk the course several times and do a clean slow first run. Look at least two gates ahead, drive the tight stuff really slow and don’t be afraid to carry some speed where it opens up. If you decide you like this then change the alignment and add some negative camber (-3 deg front and -2.5 deg rear) Good luck and have fun.

 

Thanks for reply. I have P.Corsas as well. I think these tires will warm up faster and grip better than the Cups. Looking far ahead is common practice for road racing and even street driving as well. Did you experience a lot of understeering with the street alignments?

 

My wife and I autocross our 2004 GT3 twice a month in SoCal. We also do numerous DE and TT track events with PCA. For a beginner, the advantage is that PCA provides great instruction for free. You meet lots of very nice folks. You get a fun day of driving for $40 in San Diego or $60 in Orange County. It takes years to be really good at driving, so just go out there with an open mind and listen to your instructor. Most PCA regions have a performance driving school at least once per year, and these are a bargain. Highly recommended. It is a little rough on tires, but you get used to it.
