Curt,
So far I haven't had much of a problem with the car. I've only had it to one autocross so far. But my mechanic recommended the panhard bar because he knows I autocross and feels that would help keep the rear end in line. I've noticed the car does step out slightly when going over larger bumps, but nothing that has really scared me so far. In the one autocross I took the car to, I found the car to be very loose. I ran the full season last year with a different car, so I wasn't chalking it up to driver inexperience. The car turned in pretty well, but got loose soon after. It got looser as I tried to get back into the gas coming out of the turns. I know this could be caused by a lot of things, so I think I'll try some simple things first, such as tire pressures. But I'm trying to decide if a panhard bar would do anything for my car at all, or if it's just pissing money away. I can't afford big bucks, but will do whatever I can to shave another 1/10th of a second off my times.
Thanks for your help.
Steve
