I agree for the track, track pads are better, but they're worse on the street where most spend 99.9% of their miles, even if they track.
If you track a few times a year, then you'll be prepping your car anyway, wouldn't it make sense to put a track pad on it for that, and remove them to get the best pads for the street?
Oh, btw, did I hear the occasional street race? I'm sure you do it very safely, and haven't hit any of our children yet, so when you do street race, just make sure there aren't any people or cars around. You know this is real life, not a movie, right, OP?
Upcoming NYC dates: Jan 8 and 27. See Facebook for other shows and PM me if you can make one...love to see you there!
Mangofy your E46!
