I am in need of a wheel alignment. Knowing these cars are setup with an aggressive alignment, I would like to reduce the aggressive alignment to provide better wear. I would like to keep it within the factory specs but less aggressive since this is a street only car. Saw someone posted the alignment specs but cant find them.
By chance does anyone have the less aggressive specs within he factory specs?
Thanks

I would recommend staying within the standard alignment specifications with the rear camber set at the low end and the rear toe in set on the high end. This should effectively reduce/eliminate the inside edge tire wear. Using this on my modified and lowered X50 i get almost 20K out of a set of PS2 rears and going on 30K+ for the fronts. I do a lot of long range freeway commute with some track and canyon carving thrown in.

I got very even tire wear with this setup.

I run an aggressive alignment and my tires wear perfect.

I run alignment settings very similar to what Carlo runs (more camber in front though) and I get really even tire wear.

A couple of folks asked me to post some higher resolution photos of my alignment stats. Here they are. This one is a good street set up with even tire wear.






This one is for street/track/autocross use that also yields even tire wear if you drive aggressively.

Thank you

Such perfect timing! I’m going for an alignment this week and I was going to ask the same question.
Thank you Carlo!

Factory alignment is not aggressive at all. If you are trying to increase the life of rears it's a different strategy. Alignment can help a bit but requires a bunch of expensive aftermarket pieces.

I beg to differ, and I have achieved great tire wear results just from a proper alignment with a completely stock setup.

I've got a theory... and those that have more experience, please chime in!

If we take 2 identical cars, with the only variable being the tire sizes (lets say they have 315 in the rear), the alignment can be setup to the same numbers, but I'm willing to bet, the wear characteristics will be very different.
I think this, because the plane that the alignment machine is using, is going to be different, relative to the contact patch (cross-section).

Do the alignment machines take into account the tire sizes and wheel offset? Because the numbers are based off the stock wheel / tire setup...

Carlo_Carrera

Yes. If you are running non-stock tire sizes the alignment numbers might need to be tweaked slightly to achieve the best performance. A good shop will know how to do this.

All my cars that are lowered wear out the inside inch. Especially the turbo cars. I’m lucky to get 5 to 6000 miles out of rear tires. I have taken them to multiple higher end places to align. The rear tires don’t seem to like the extra camber and any toe in that inside. Wife’s 996 stock height no wear issues.

If lowered enough you need the rear toe arms to get it to where you want.

Capt. Obvious

Your issue sounds like you need adjustable arms for the back because you're out of adjustment on the OEM bits.
