Agree, no need to take off stability if you drive better with it on! My driving style makes it freak out and it slows me down, but I know some other very quick drivers who leave it on all the time (sport mode) and do very well as well!!

I posted a few pics in my build thread on the rear upgrade I just did as well... same goal, slightly different method of getting there. I'll repost here for comparison though!

5.Monster & dmichaels - thanks guys. Yeah, it was not even a close competition for me to choose...TC/SC off or Sport Mode. Night and day. I could not get the car to hook up with TC/SC off. And I was just too loose every lap, no matter what I tried. With Sport Mode I was much faster, very controlled, balanced, and secure. That's my comfort zone!

dmichaels - looks like yours is good!

Man oh man I hope this is the ticket to keeping those rear brakes cool on track days now, finally! After a very hot day with a lot of laps, the rears look solid, no fade, no overheating, no scored rotors, I'm happy. And I really like that I spent $300 in parts and re-used so much of my original stuff. Whereas a full kit costs $600 (I'm sure that is great too, I just like $300 still in my pocket for gas money!!).
