I used to autocross a lot growing up. I started out in a 71 Triumph Spitfire and moved up to Formula Fords, then Formula 440, and various street cars. I would really like to get back into it as we have an excellent place to run (has been held in the same place for over 40 years). I have a Convertible ZHP, unfortunately with the 5sp auto and I have been reading up on the weaknesses of the E46 and cracking. I am not looking to get terribly serious, but I will run another set of wheels and tires, and I am upgrading the brakes to stop techs and that will be pretty much it for now. My ZHP sits low enough already as I drag the bottom more than I should so I won't be lowering it.

With all this being said, if I run her once a month or less frequently, do I need to be alarmed about the structural integrity of my E46? If I get real serious again, I may just buy and E30 or an E36 and gut it to build a autocross/track car.

Thanks!
