My last car was a '91 Mustang coupe. It had over 500 rwhp and it was a blast at the 1/4 mile, but on the street it was a pain in the ass. The reason for selling it was to get a car that would have very good street manners, which is why im looking into an M6 T/A. But I was wondering how well this would work out. I've been looking at alot of the photo albums on here of people that race in NASA and SCCA and their cars have no interior except dash and a seat with a 12+ point cage and no creature comforts. I wanted to make a nice street car that was fun to drive around town but would still hold it's own at the track. is this possable? im not planning on going for national titles or anything, but just be competitive locally. I wanted to have a system and full interior in my car to keep it enjoyable for myself and all of my friends, but at the same time i want to be able to go out to the speedway when SCCA shows up and make a few laps and do well. is this possable or just a dream?

Yes, it is certainly possible. But first you mentioned autocross, laps, SCCA, and speedway. Are you intending to run laps on a speedway or autocross (course laye dout with cones).

It isn't unreasonable to set up a suspension that will do both well, but one big difference is brakes. Autocross brake pads work well on the street (and strip). Road course / speedway laps require higher temperature range pads that DON'T work well on the street, so most people swap brake pads for track day.

On autocross, there are different classes that allow different levels of modifications, from stock to fully gutted and built race cars. Stock is of course the smartest choice, and ESP is one step up and allows quite a bit but you can still keep the car streetable.
