I'm taking it in for the one year anniversary oil change. I have 2300 miles. Inside edges of MSPC showing some wear. My question is, for street use and tire life should I have them take some camber off the back wheels. It is set at whatever it came from the factory with.

 

Stick with factory set up...

 

It is the toes that eats the tires up more so than negitve camber. Make sure the toes is also with in spec...as a matter of fact the less toe the better and every little bit counts.

 

If you reduce rear toe and Rear Negative camber , You WILL get more tire life. You will also notice more tendency towards oversteer so be aware and use caution. I often change my street only cars away from factory alignment to get significantly better tire wear.

 

I was having the same problem....3400 miles on the rear MSPC with -2 camber.
Took it out to 0/neutral and the car runs great for the street, but I would change back for the track.
