My specs are where a stock (no mods) HHR should be.

 

You could leave it at -2 degrees, yes, and you'll likely be OK...it's only 3/10ths of a degree outside of the specification. However, if you value tire wear above all else, you may wish to get the camber more towards the middle of the range, which appears to be about -1 degree.

That being said, if you also installed larger-than-stock wheels/tires, be sure that if you move the camber back in the positive direction that you don't then encounter interference with the inner fender lip. Sometimes that extra bit of negative camber (like you have with -2 degrees) comes in handy to help create the additional clearance needed for larger wheels/tires.

 

OK just to make sure everyone knows I did install the camber bolts and set camber at -1 with no issues with my front tires rubing fender (20" wheels) I have the forte rims I believe that they are offset 40 and neither back or the front rub but I did use the Eibach pro kit not the Eibach sport line or the Goldlines . Hope all this info is helpful to someone it is nice to have an idea of what you can expect when doing a mod and thx to Hahn for telling me where my camber would be best suited for tire wear .
