On an 03 sedan with prodrive springs?
Any reason at all to buy ones?
Are the stock bolts in back adjustable?

 

Rear camber is not adjustable from the factory. If you want to adjust the rear camber you will need either camber bolts, camber plates or adjustable rear control arms (lateral links).

 

I have Tein S-tech's and tokico shocks and when i had my alignment done, the rear tires are slightly out of spec and you can't adjust them with the rear camber bolts. I have noticed uneven tire wear on the rear tires.

 

The factory settings are not set to optimize handling. They are set for safety (understeer) so if you want the car to handle better you need to max camber in the front and run around .5 less in the rear (not possible with oe rear bolts). After I installed a set of SPT's I maxed the front but my rear camber was at -2 degrees which is way too much for me so I installed a bolt kit, set the rear to -1 and I like the feel of the car better now.

BTW, driving style also comes into play so there are people that run more - camber in the rear but for the most part people max it in front and go with around -.5 less in the rear. If I remember correctly BAN SUVS runs more - camber in the rear and he's very happy with it.

Also, the more - camber you get rid of in the rear the closer the rear tires get to the fenders so if you are running a wide tire that is on a wheel with a low offset you may have rubbing issues.

Taerron, what is you’re rear camber and toe set at?

 

I'm not sure off the top of my head, I will get back to you with the info. I'm on lunch break so I dont have time to look for it.
