and in terms of e36 vs e30, the e36 has a much more advanced rear suspension, but it weighs on average a lot more than an e30. so it really comes down to driver skill and confidence. In a straight line im screwed, but hand me a few corners, and i can catch up.
jsut wait until the 328 goes on a diet. i never use my ac so i think i might lose that next spring. also thinking about some nice light weight seats. bex are the seats that the guy that you know makes light weight and high quality? if so i would consider looking at those. all that should shave a few hundred pounds off
