Help with Alignment

[jeguzik]

Can I get some assistance with Alignment. I have a 2013 on H&R OE Sport springs and had inside tire wear previously. The attached is after an alignment. I was going to take it in again, and wanted advice on what was the correct alignment spec for my car on the OE Sport springs. Thanks!

Apparently toe is what eats tires. It doesn't look like you have too much though...maybe they can reduce even further to maybe 0.06.

I had much more aggressive settings but I autocross and my tires last from May to September and at that point they have very little tread left...that was less than 8300 km on a brand new set of RE-71Rs. So long term wear is something I don't have visibility into.

I have H&R OE springs and was running about 2 degrees of camber which was killing my front tires on the inside. I just had it realigned to bump up the though a quarter inch which they say should help with the wear. Otherwise the only option is adjustable control arms to get the camber back in spec.

OP. the alignment you received is probably the best you are going to get.
Toe will cause a tire to have a "choppy" wear on the inside or outside treads near the shoulders of the tire.
Camber will cause an even wear on the inside shoulder of the tires.

On B8 Audi's the front camber is considered not adjustable with OEM parts. The only way to realign the front camber is to buy adjustable control arms.
As our cars are lowered, it caused the camber to increase (become more negative) due to natural laws of physics.
The reason that it appears that camber was adjusted from old to new can be a result of toe adjustment with the tie-rod tension on the assembly.

-2 up front and -1.5 back is fine.

I’d like to see the toe more even side to side, especially rear..it’s not that hard to make them the same number. Doesn’t look as if they even touched it. ...a little turn on the pass rear and would’ve be good to go.

I like less toe, but that my preference. I’m basically zero toe up front and a tiny amount of rear toe. My -camber is the same.

So should I ask them to zero the Toe?

On AWD/FWD cars you want to keep a little bit of toe-out. Because the front wheels are driven they get pulled forward and toe-in naturally once you are moving getting you closer to zero. Generally, toe-out improves steering response, and toe-in improves straight line stability. Too much toe-out causes the inboard edges to wear out. So it all depends on what you are after, but your main issue is the out of spec negative camber in the front that will give you uneven wear on the inside.

Not trying to be a wise ass here... but by 'natural laws of physics' do you mean gravity? Is it because the car's center of gravity is lower to the ground relative to the wheel hub/center/axel?

Correct.

For example, take to drinking glasses and put a ruler across them. So, that the glass at the end of the ruler. Push down on the center of the ruler and you'll see the ends raise. This is essentially what is happening.

Great way to describe that. Thank you.
