Last year I requested a copy of the published road race Z06 alignment spec. Someone was able to post it and I need it again. It included the amount of negative camber, toe and caster needed to make the car stick at the track.

Anyone have it??

 

check this site, don't know if it is the one you want, but they do have one.

This is the 'Agressive' autocross ZO6 setup suggested by one CFer....

Zo6 alignment for autoX posted on corvetteforum by TedDBere March 2005

Lower the fronts all the way and the backs to within 2 threads showing. Drive it for a couple weeks to allow the suspension to settle, and check your ride height at the jacking points on a level surface. Equalize the front height if required and adjust to a rake of 0 to 1/8th inch.

Rake ... 0 to 1/8 inch, as measured at the jacking pints, for autox should be OK.

Camber Front:
At least -1.75
Rear: Maximum but equal, about-1.2 to -1.5.

Caster Greater than 6.0
toe? Front: 1/8th inch total toe out, Rear: Total 1/4 inch toe-in

Cornerweight after you have allowed the suspension to settle with the ride height you like, and before you allign it.
______________________________
Thats a real agressive setup, and you can't do it with runflats, sidewalls are TOO stiff, and you'll wear out tires like mad! Here is what a guy who does alignemnts has to say .......Sorry I forgot to get his 'handle' on the forum when I copied the thread for my personal Vette Notes, He posted.......

Alignment specs for autoX and street

I do alignments all day mostly for porshe and mercedes benz and a weekend racer so i have alout of experence with alignment specs. On my frc i origanly aligned it to zo6 specs. tire wear was almost even but the car felt heavy, slow turn in. the second time i aligned it i bumped camber up about .2 more negitive and caster about 1.5 degreese more positive. the car felt 300 pounds lighter. it turned in real easy and tire wear was even. more caster=more stable at high speeds less caster=quicker turn in
___________________________________
When you go more neg Camber, go more toe out. The end product is keeping as much rubber on the ground. Freeway driving, you probably do not want alot of neg camber. You will see tire ware. But neg camber is good for the canyons. You have to sacrafice a little to have both.
____________________________________
Starting point for street and autoX
tire pressure front 34
rear 32

ride ht. front 27-1/8
rear 27-1/2 to 27-3/4

caster front 5.5 deg
rear N/A

camber front -0.7 deg
rear -0.5 deg

toe front 1/64 out each side
rear 0.00
____________________________________

I am basing this off of Z06 specs also....

Front:
Toe In +.06
Camber -1.0
Caster +6.9

Rear:
Toe In +.02
Camber -.80
________________________________________-

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.

________________________________________ ____
Front
-3/4 neg. Camber.
Toe (out) 0 to 1/4" it's up to you. The more toe out the better. But worst tire wear.

Rear
-3/4 neg. Camber.
Toe (in) 0 to 1/4" it's up to you again. The more toe in, the better the rear will stick in exiting corners. But with more tire wear.

Steet/Road Racing

---------------------------------------
Or go a little more aggressive............ I think I am going to try this one myself.

Maybe a little more tire ware but not very noticable.....

This is still within Z06 spec's I beleive but not within C5 spec's. My 2000 C5 does have the Z51 suspension package though.

Still would like more input from you, the pros..........


Front Individual Toe +0.03 degree

Front Sum Toe +0.06 degree

Steering Wheel Angle 0.0 degree

Front Individual Caster +6.9 degree

Front Cross Caster within 0.50 degree

Front Individual Camber -1.0 degree

Front Cross Camber within 0.50 degree

Rear Individual Toe 0.0 degree

Rear Sum Toe 0.0 degree

Rear Thrust Angle 0.0 degree

Rear Individual Camber -0.80 degree

Rear Cross Camber within 0.50 degree

That's all I have to contribute! Have fun!

Yeah!!!! Thats it!!

I appreciate everyone who posted regarding my request!

 

Will these alignment specs work on a '99 coupe?

 

As long as you don't have runflats they will work fine.
