Does anyone know of any good ways to knock off ~0.5sec off of 1/4 mile for around $2500? I looked at chips and hi flow air boxes/exhaust and these don't seem to do much. (check out dinan's own links to C&D test reports, NO improvement in 1/4 mile times in all of their modifid M3s except supercharged M3!! Waste of money!). I posted one earlier looking into N2O but havent had any valuable inputs yet. Did I make a mistake of not spending $5000 more to get a 328i? I just didn't think that premium was worth it.
Know of any good URLs for E46 performance??
1999 323i manual sport package
HK with CD (don't buy one without it!!)
Just got it a few weeks ago, paid $1300 over invoice.
