i recently bought some rpf1 the staggered supra fitment, 17x8.5 and 17x10 with a 40 and 38 offset respectively.I am grunning 275 40s on the rear. Got My tire mounted and balanced at STS. The guy who aligned them said Since I lowered it the factory spec alignment wouldnt work. I got my car back no problems in the front but the rear was a disaster. The spec sheet for my rear wheels rear reads:

left rear

-.9 degrees camber
.25 degrees of toe

right rear

-1.9 degrees camber
.25 degrees toe


The diagram shows my rear wheels at less than a 90 degree angle mean the wheel and tire is slanted away from the tire well which I always thought meant overly positive camber.

what can I do to correct this

leaning in at the top = NEGATIVE
leaning out at the top = POSITIVE

Usually, lowering creates negative camber, some of which can be corrected with camber kits.

it has sick positive camber. What do you think caused this. I recently got into a rear ender fender bender,could that have possible caused that..If I got a camber kit it should correct my issue but would I allow me to have even tire wear

I'm not really following this contradiction

Did the alignment shop screw up that badly??...or is there some other confusion here?

lisc300

ok in reality the shop negative camber reading was really positive because the top of the tire is pointing out from the fender. I thought a car being lowered causes negative camber..what can be wrong..I recently got into a car accident could that have caused the positive camber..

Absolutely. But if your alignment shop is telling you it's negative and you can see it's leaning out at the top, you need to find a more reputable shop.

i wouldn't jump to conclusions...

are you sure your eyes arent playing tricks on you? What the shop said is probably the correct numbers. Something isn't adding up here. Your 3rd post is contridicting your first post. You have Negative camber in the rear if the top of the tire leans toward the car. If it's positive the top of the wheel will lean away from the car. So which is it?

Also to correct those numbers i would try to bring the right rear in (more positive) or get the left rear to lean out (more negative)

^^ your post seems to imply that camber is adjustable



To the OP, how about posting some pics so we can see what you're seeing.

because it is....to a certain point

^^ true, I was just assuming the shop had his adjustments maxed. Still seems they should be able to get the left rear closer to the right though.

That's because it IS. As is every other alignment angle on the car.

just as long as you can get the numbers on both sides close to each other it shouldnt be too much of a problem. I'd rather have both rear tires wear down faster as opposed to just one wearing down faster than the other. If the tech can't get the numbers to move any more, then you might have to look into replacing more suspension parts.

question: have you had the car aligned before swapping to coilovers? just trying to get a history on the car.
