I just replaced my OEM suspension with Bilstein B8s and Eibach springs (B12 Pro Kit). I am getting the car aligned and wanted to see if there are any desired specs for a pure street car. I am not an aggressive driver looking for ultimate grip, just want something that feels good and doesn't eat inside edges of tires (PS4s by the way).
As much negative camber up front as you can with very little toe in the rear. Have your alignment shop use the GT3 settings knowing the front camber will come up short. And use the lower side of any toe spec to reduce tire wear, especially in the rears. If the car is too twitchy afterwards add some toe up front.
edited: and seriously consider getting the DSC suspension control box to replace the factory PASM control box. It's simple to install, helps tremendously with PASM cars, and can be removed and resold in the classifieds when you sell your car
.
I'm happy with what I'm running as I have adjustable everything and GT3 LCAs - but you can follow suit to GT3 spec like above.
The outside area wears out first on my car , all 4 ?
Wondering if I should have an alignment done for the new rubber ?
For sure. Means you have positive camber which is not what you want for handling or you've got too much toe in and the tires are.kind of scrubbing sideways going down the road.
Front axle "toe in" means the front of the "steerer" tires are closer together.
So, is "toe in" condition a negative number or positive number? i.e Toe in is for example sake - 0.5 degrees?
Rear axle toe is where I am confused.
Is rear axle "toe in" where the rear tires, rear edge, (closest to the exhaust cans) are closer together? is that a negative number too? Say, -0.2 degrees? This confuses me, the little diagrams boxed in red as compared to the positive angles shown in the result.
Toe means the the tires are towed in so the bigger the positive number the more toe or inward angle they have at the leading edge. If the number is negative that results in toe out, which you don't want.
