Project E46 M3: Part 15 – more exhaust testing and weight reduction

,


For you E31 owners (are there any out there reading this?), my father was able to find a nice stereo that retains the factory look, but plays CD’s, MP3, has SiriusXM satellite, etc. As you can see, it’s a very nice touch with newer school technology.  It’s from a guy on Ebay in Europe, and the Euro harness adapter is included because it was apparently slightly different.

Going back to some wheels and tires talk, here’s something I wanted to share with you. On Project E46 M3 we’ve running BF Goodrich’s Rival extreme summer performance tire, and it’s been outstanding. Holding over 1 G in turns with our stock suspension is no problem (we’ve hit up to 1.21 G at just 65 MPH). But what we wanted to show you was the even wear—because this car has no camber plates. The saw-tooth blocks come down over the sidewall just enough to keep the good rubber in contact with the ground, and right up to the very edge.

Conversely, you can see what happens when I try to take the same turns in my daily beater Cadillac Catera (yes, the Opel Omega one). With these all-season cheapies on them, I’m liable to cord the tires on any of the next few turns.  Contact with the road is happening nearly two inches past the tread, and I’ve already erased some of the writing. No, it does not hit over 1 G.

Stay tuned as–just as I was buttoning up this article–the UPS man came to the door and dropped off the next performance upgrade!
