so after I lowered the car, and run 315 tires, the best alignment I could get was a -1.55 on the rear. Im sick of eating the inside line of the tire while the rest of the tire looks unused. Is there any camber plates or anything out there available to help get me to a 0 degree camber?

 

What is your rear toe?

 

I run -2.0 in rear, GT3 ride height, with minimal tire wear problem. I would agree that Incorrect toe is much more likely to be your problem.

 

It's your toe in. I run -1.9 rear camber and while the rear does wear a bit faster than the rest of the tire, it's not too bad.

Rear adjustable control arms would help, but you may find you need to roll the fenders with those 315's. I'm running H&R springs with 315's and the local independent Porsche shop said if they pushed out the tires, I'd be at risk of fender rubbing.

 

I rolled the fenders, they rubbed horrible. My tires look brand new except for 2" on the inner side. Already bands showing through. Here is my alignment

 

I'd bet you have some worn rear bushings which are allowing toe in shift under load, should also dial in some rear toe-in while under there...

 

Something is sure up and pissing me off. When the car is sitting the tire sits flush. When I took them off,I noticed the wear is so bad, its actually worn down the side of the tire where the lettering is.

 

V the car cannot feel right. You will solve your issue by adding in toe. Try .20 in. What is happening is that under load the tires are opening outward shredding themselves. It make s the car feel super loose too.

Try this:
- Max front camber negative. (won't be much). Your rear camber is as low as it will get.
- Front toe 0.0 or green.
- Rear toe .20 in.
You will love the feel and the tires will wear better. It's a bit more rear toe than stock because with 480-500 hp you will squat more than stock and tow out 15-25deg.

I guarantee you will be happy. Let me know if I can help with anything.

 

^ exactly...if wanting to run on the 'edge' of alignment numbers, need monoball/bearings vs rubber bushings, way too much deflection under heavy load

 

Here is my 5th set of tires in a year

 

I have noticed that after i lowered it, and the alignment it has felt loose under initial load. Like all 4 tires were spinning. How can I adjust this at home? My alignment shop is over an hour away, plus I don't want to spend 300$ for a bolt to turn a couple mm.

 

something WAY wrong, that's like 15degrees of camber not 1.5 .....

 

What could it be?

 

surely setting the toe positive by .20 cant fix this bad of an issue can it?

 

are you on 19's? 19x11 19x12?
