Front end alignment specs?
Can someone link me to the proper front end alignment specs for a 1990? Specifically toe and camber... Thanks

Racinfan, according to FSM section 3 page 3A-6 ... the specs are - Caster +6.0 degrees+/- .5 degrees
Camber is +0.5 degrees +/- .5 degrees and individual toe is 0 degrees +/-0.1. This is with full tank of gas and jounced 3 times. |

Re: Front end alignment specs?
Cool. Thank You! I was sitting behind the car yesterday at a show and it sure looks like it is "toed out" - which could be part of my vibration issue. It drives fine but I'm gonna have it aligned now..

Re: Front end alignment specs?
Funny I just came on here to search for this thread...
 I appreciate the link - already downloaded and printed it. I haven't had time to take the car to the shop for alignment yet - was actually there for something else the other day and the guy mentioned when was I gonna bring the Vette in.. I told him I had to get the specs first. And waahlaah - here they are! Gotta love this site!

Re: Front end alignment specs?
Please note that these specs are symmetrical. For example, when we recommend 1/8" toe in, that indicates 1/16" on each front wheel for a total of 1/8" total toe in.

Re: Front end alignment specs?
Please also note the use of positive camber simply has to be at the advice of lawyers. We never tried the ZR-1 at factory alignment settings but our 88 Z51 car was absolutely un-driveable in any performance sense with the factory settings.
My advise - unless you are seeking NCRS only - is to seek out a shop that can vary from "the book" and use pretty much any of the published performance alignment specifications. Good luck, - Jeff

Re: Front end alignment specs?
Well this guy can do whatever I tell him to plug into his machine. So he says. I'm not looking to race the car - just a good all around setup for normal driving.. Was thinking about doing the "Advanced Street" settings on that vb&p link above. Will that one be good???

Re: Front end alignment specs?
I'd be interested to hear opinions about recommended settings (camber and toe) for a street driven (but not daily driven) ZR-1 (with stock suspension) for occasional mountain runs, autocrosses and track days. In other words, a good compromise alignment.
