Street Use Only:

I'm putting new Michelin Pilots on and want to check alignment specs.

I have the Pfadt Chart and have read a number of posts on this question, but what is the consensus?

Front: Camber: 0 to -0.8 or anywhere in between
Toe: 0



Rear: Camber: -0.5
Toe: 0



Thanks,
WR

Those settings would be for someone who just wants good tire wear. If you want better performance youre going to need to add more negative camber.

rear toe is fine, but you can set it a bit more negative as well


common street setup is:
front
-1.2 deg camber
0 toe

rear
-0.9 deg camber
-1/6" toe

good high speed stability, not too aggressive, but handles well

Tire wear 0 camber and 0 toe front rear 0 toe and 1/2 degree neg camber. Unless you street race on curvy roads this is good have it on my z06 can't tell big diff and i drive curvy roads in mountains.

I use Pfadt's street numbers and am very happy. Seeing good even tire wear too. I went from 0 camber and toe, which was squirrely, the car wandered. The street alinement has worked well for me.

The more camber above the recommended street specs will just bring on increased wear with a boost in performance too. I personally do not think it is needed for the street though at the high cost of tire replacement.

If you got the $$ though get aggressive if that what you need.

I tried this on my 09 z06 at 12000 miles when I replaced the tires at 25000 miles or about 13000 miles later I had the same results inside of tires were gone. So use this if you want to but not me. I don't have the wandering you are talking about in my 2012 and the 0 toe and camber is what its set at had it done at 500 miles.Oh if your tires are already worn in or set this may cause wandering with this alignment.

I have maybe 12,000 mile on the F1 super cars and I can not detect any uneven wear. If it is present it is very minor. The tire's were purchased with the rims and maybe had 4,000 previous mile on them, for a total of 16,000 miles. My tires look like they have a lot or tread left too.

I do have the Z51 sways and Koni FSD shocks too.

Yours being a Z06 I wonder if that means anything?

Hey guys! Couple things to keep in mind when it comes to alignment...

1. Your alignment is only as good as the tech performing the work. You own performance cars, take your car to performance shops for the best results.

2. It's not camber that generally kills tires, it's Toe. We would expect our Performance Street alignment spec to offer better performance than a 0 camber 0 toe setup with minimal additional impact to tire wear.

Here is a copy of our alignment guide, click the photo for a full printable version. Please feel free to use it as you see fit!

On my Z06. I reduced the front camber from -1.2 to-.9 and near zero toe and the rear camber from -1.1 to -.6 and near zero toe. Can't tell any difference in handling.

If you want good tire mileage with no inner tire wear

Front
Camber ..... - 0.4°
Toe ............. 0.0°
Caster ......... Stock Spec


Rear
Camber ..... - 0.4°
Toe ............. 0.0°

Thanks for all the info, I will take it to my aligners when I get this done.

I went with your street spec and have about 3k miles since and all is wearing very even. The car felt much more tighter/precise after the alignment handling seemed much improved..I have seen two factory spec GSs both are showing front outer tire wear???.

I had my 2010 GS had my alignment done yesterday and it seems to steer and holds the road better. I also used Pfadt's street numbers.

That is what I have as well.

I just today had my '10 ZR1 aligned (targeted) to the Pfadt street performance specs. Used Southwest Alignment on Richmond Ave. in Houston. The owner, Greg Turman, did the work himself. His shop has the Hunter Hawkeye System. Excellent job...the "before" measurements were definitely out, especially the toe.

The car has been in service about 14 mo's, and I recently noticed the outboard tread section on the front tires appeared to be wearing a bit more than the rest of the front ties. I realize that I did let this go too long before having the alignment checked.

before
camber LF -1.4 RF -1.1
caster LF 8.3 RF 7.9
toe LF .29 RF .21

camber LR -1.5 RR -1.0
toe LR 0.04 RR -.09


after
camber LF -.7 RF -.8
caster LF 7.5 RF 7.7
toe LF -.01 RF .03

camber LR -.6 RR -.6
toe LR 0.02 RR -.01

Right on. Later! Frank

What exactly does caster do to tire wear and handling? And what are the factory alignment specs, including caster? Thx.

The 'performance street' numbers still have a lot of variance. I was thinking of going the least aggressive of them:

FRONT: Camber= -.07, Caster= -7.5, Toe=0
REAR: Camber= -.04, Toe=0

Does that sound good? And final question: How precisely can an alignment tech get to those numbers??? Thanks gang.
