I'm looking to buy an E46 M3 to tide me over for a while until the initial M4 craziness dies down in a year or so. My E92 M3 lease is up end of Feb 2014 too. I've always wanted a track car, and I've always loved the E46. For now it needs to remain a street legal DD, but I figure I'd like to bring the performance up a notch.
If you had a budget of like $6k or so (maybe $7k if it's needed), what upgrades would you put on a bone stock manual E46 M3 coupe? Remember, it should be a DD-friendly car. When it comes to suspension, I don't mind a bumpier ride, but I don't really want to lower it much at all. The speed bumps, pot holes, and drainage bumps in LA aren't sports car friendly.
