Default Alignment Specs - street car only

Hi all,

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).

Thanks

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.

Thanks. I swear I searched “alignment specs” in this forum and that thread did not come up.

I got 25,000 miles on my Michelin AS/3s with this spec. Caveat: this is a 996

I go with aggressive front neg camber for the street, and still wear out the rear tires before inside wear becomes a problem up front.

Don''t be shy!

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.

Default Rear axle toe, front axle toe.

Question of perception.

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.

Please send help!

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.

For the rear, some toe in is desirable, as squat under acceleration reduces toe.

And as mentioned by @Petza914 - toe out is not a good thing
