Alignment...did this guy do me right?
Hey guys,
Took my car in to get aligned after lowering. I asked him to align it for a good compromise between track and road, leaning towards road for decent tire wear. This is what they did for me:
Left Front:
Camber -1.4
Caster 8.0
Toe 0.03
Right Front:
Camber -1.4
Caster 8.0
Toe 0.03
Left Rear:
Camber -1.5
Toe 0.04
Right Rear:
Camber -1.3
Toe .07

Check out this link from a supporting vendor: http://www.vbandp.com/instructions/h...ruct/align.htm
I don't think I would be to pleased with that alignment. Just my opinion.

Compared your specs to what I recently had done. I would consider you have too much camber front and rear. Perhaps too much caster too. My set up is street Z06 for handling and good tire wear. Sounds similar to what you are looking for in your set up.

With over 1 degree negative camber, you are going to get really aggressive inside wear on your front tires. I found with wide tires, you will need to be close to zero camber to get acceptable wear for street driving. I left mine set at about -1/8 deg camber in the front. I don't think that caster causes tire wear. You just want the caster settings equal from side to side to make the car track straight. Some shops will dial in a little more caster on one side to compensate for the crown in the road. Same with camber. Some will put a little more negative camber on the right side to make the car track straight on a normal highway.

Next time, ask for specs here first.

Well snap, I searched all morning and didn't find a ready answer so I figured close to specs would be close to what I'm looking for. Seen some posts with similar specs as a good compromise.
According to the GM specs they had, these were just a tiny bit outside the stock specs.

Those specs are great... if you want to run on track too 
I'm running similar, but less caster. You want caster between 6 and 8... I'm at 6.9-7.
Front
-1.7 degrees camber
0 toe (toe is what kills tires very fast)
+7 caster
Rear
-1 degree camber
1/16th toe in per side
Your car will handle amazingly... far better than stock, but at the expensve of more inside tire wear. You can check them periodically amnd have the tires flipped on the wheels so that you can wear out the other 1/2.
Works for many guys that want a dual duty setup.

also it helps if you are on non runflats .with a fairly aggressive setup the non runflats show less inside wearjohn

This is a double thread post for me. I'm just looking for an answer.
I have a Y2K car that has both the front tires wearing on the INSIDE. The tires are oem runflats and the car has not been lowered. It has
21K miles on it and is driven in a conservative mode without roadracing.
I am in the process of finding front tires and plan to correct the problem before the tires are replaced. I am not a tire front end type of guy, but I would like to know how to correct this problem from recurring when I replace the tires.
I know a lot of these C5 cars have front end tire wear. I want to correct the problem before I end up with tires wearing to the cord on the inside. Others have had the problem. What has fixed them???
As far as runflat tires go, I'll say this. I saw A-L-O-T of Corvettes at Carlisle this past weekend, and a quick glance thru the C5's showed the bigger majority of these cars all shod with Goodyear RUNFLAT tires.

Here is my alignment run I got today, it has the specs too. Couple things are just outside the specs. The steering wheel still isn't straight with a left bias.
What do you guys think, should I take it back and have them set the toe to 0. And what about the steering wheel off center?

I run a - 1.3 camber setting on the front with just a touch of toe in to keep the car from wandering on truck ruts while driving on the street/highway. I do not get additional wear on the inside as I drive pretty aggressively so the outside edges of the tires always get a good workout with corresponding comparable wear. At -.8 camber in the rear the tires pretty much wear evenly across the tread.

I had mine done recently with the following specs:
Front:
camber: -.75 degrees
caster: ~7 degrees (as much as possible while still maintaining the camber)
1/16th toe in (.0625)
Rear:
-.5 degrees camber
1/8 toe in (.125)
The stealership only charged me $75, but it took them almost 2 hours to get the specs right on the money for what I requested. I was given these specs by a trusted source who says it is a good balance of cornering with tire life. Thanks Randy.

Not a bad price, they did mine in 35 minutes. I opted for the lifetime because they offered a discount that was too good to pass up when I declined. Since they do all Roger's Corvettes I thought it was a safe bet, but my steering wheel is still off center. Good news is that I can take it back and try a different tech if I choose.
