Wheel alinement settings ?

[killain]

This may sound crazy, but I was wondering if there are any specific wheel alinement settings for the C-5 platform? Such as compition driving settings or better touring settings and the like. Or is the wheel alinement settings all one desired settings for the four wheels? I notice from the wheel alinement printout that I got, that there are a range wherein the settings should fall, but nothing specific? Any comments please !

They can set them for anything you want.
They are probably set up for what the alignment computer says the factory specs are.
GMjunkie and I have been running
0 camber all 4 wheels
0 toe rear
6 degree positive caster left, 6-1/4 degrees positive caster right.
1/6" total front toe in.

With good results and good tire wear.
This is less caster, camber, and toe than factory specs.

Pete, I think you have the Caster settings backward!! 6 deg + caster Lt, 6 1/4 +caster Rt.

Woops, I fixed it.
But you know, I can't find the factory specs anywhere. Do you know what they are?

Don't know regular C5 ... below for Z06; note at end for more aggressive setting.

This is the factory specifications for the ZO6, 01 and up. These are different than regular C5 specifications, so some shops alignment machines may not have the right databases loaded to show this:

Front Individual Toe +0.04 degree +/- 0.10 degree

Front Sum Toe +0.08 degree +/- 0.20 degree

Front Individual Caster +6.9 degree +/- 0.50 degree

Front Cross Caster within +/- 0.25 degree

Front Individual Camber -0.70 degree +/-0.50
degree

Front Cross Camber within +/-0.25 degree

Rear Individual Toe -0.01 degree +/- 0.10 degree

Rear Sum Toe -0.02 degree +/- 0.20 degree

Rear Individual Camber -0.68 degree +/- 0.50 degree

Rear Cross Camber within +/- 0.50 degree


For more aggressive track/street use, increase front individual camber to 1.0 degrees, and rear individual camber to .8 degrees, while reducing front toe to .06 degrees, and rear toe to the minimum (.01 degrees). This is a very drivable setup and increases mechanical grip noticably. Some auto-crossers will get even more agressive, setting rear camber at 1.1 degrees and front at 1.5 degrees, and toe-out the front at .02 degrees, but this will cause a lot of tire wear on the street, and make the car a little "darty" on regular surface streets, but makes them really grab on tight courses on marginal surfaces

less caster will help tire wear.
You can get by just fine with 4 degrees

I set mine by the spec Junkie shows.It can in some cases almost double your tire life.But if ya own a vett ya got money to burn . :blue:

revised wheel alinement settings.

I had a all wheel alinement done by a very reputable shop here in Delaware county, the settings from the Hunter alinement machine are as follows:

Left front: camber, -0.4 before: -0.1 specified range: -0.7 degrees to 0.3 degrees
caster 7.4 before 6.7 specified range: 6.9 to 7.9 degrees
toe -0.01 before: 0.03 spec. range -0.03 to 0.07 degrees
Ride height: 16.5

Right Front: camber: -0.2 before: 0.3 spec range -0.7 to 0.3 degrees
caster: 7.8 before 7.0 spec range 6.9 to 7.9 degrees
toe: 0.01 before: -0.02 spec range -0.03 0.07 degrees
Ride height: 16.5

Front: Cross camber: -0.2 before -1.2 degrees spec range: -0.5 to 0.5 degrees
cross caster: -0.4 before -0.3 spec. range: -0.5 to 0.5 degrees
total toe: 0.00 before 0.01 spec range: -0.06 to 0.14

Left rear: Camber: -0.3 before: -0.4 degrees spec range: -0.7 to 0.3 degrees
toe 0.01 before: -0.03 spec range: -0.06 to 0.05 degrees
Ride height: 15.3

Right rear: Camber: 0.3 before 0.5 spec range: -0.7 to 0.3 degrees
toe: 0.01 degrees before: -0.08 spec range: -0.06 to 0.05
Ride height: 15.3

Rear: Total toe: 0.02 before -0.011 spec range: -011 to 0.09
Thrust angle: -0.01 before: 0.05 spec range:-0.10 to 0.10 degrees

So you can see the mechanic at the Chevrolet had some of the alinements off spec and the car didn't handle well either. Hopefully these alinement angles for a C-5 coupe will correct the problem I had.
