Of course there are several factors that determine wear patterns, so your mileage may vary.
Yes, I'm almost certainly giving up some absolute grip in the rear by dialing camber back a bit there, but considering that this car understeers pretty significantly (even with camber plates), if anything this change should get me closer to neutral handling. I also installed 255/35 tires on the front, which helped a lot, but even with those two factors my car still understeered a bit even with -1.8 in the rear, so -2.0 in the rear paired with stock front tire sizes would make that even more noticeable. But like I said, the rear camber reduction came mostly because I was annoyed at having to throw out two sets of rear PSSes way earlier than would have been necessary based on the rest of the tread grooves, not as much for handling considerations. In any case, you definitely didn't need to increase rear camber just because of the front camber you added; your car still would have understeered even if you'd left rear camber alone, and now while you'll probably have a bit more grip in the rear, that means you'll also have more of a tendency to understeer.
Just something to keep an eye on. Have fun out there!  |
makes sense, about the squatting under power. For the track I do run 275/35/18 square, and on the street is 275/255 19 PSS. I'll report back soon on how it all is.
Thanks again
