HELP!!! Alignment Question!
Please help! I've been doing a search now for over an hour and I still can not find a solid answer! I'm going to have a 4 wheel alignment done on my 2006 F55 C6. I want it to be set up for the next step up from street driving but not too aggressive like track driving. I've read many different opinions about the factory specs. Some say don't use them some say do.
In short, what alignment numbers for camber, caster and total toes should I use!!!! One guy wrote he does over 1500 a year and he uses 1/4 negative camber and 1/8 inch total toe in. Great but....everything I see is in tenths, not fractions- so I'm confused!!
Any insite would be GREATLY appreciated.

You probably will get many differing opinions about what to run but this is what works for me, and I do in fact run roughly 1500 vehicles yearly on the alignment racks. I have these settings on my C6, along with many other C5's and C6's along with Z06's. These are not track numbers, but on a little back road run last year with me in the lead I hit up to .82 on my g-force meter.

That would be me, 1/4 negative degrees camber front and rear. As far as toe, we measure in inches and not degrees so my toe reading is 1/8" toe in total front and rear. I can get you a degree reading on Monday for toe if you need.

Do you know where yours is now? It might be enough to just set it up correctly at the high side of factory spec. If not then you could try the factory Z06 (FE4) settings. Here's an informative thread with the '08 factory specs chart included. The '05-'07 rear specs are just a little different.

Thanks Jeff78! Yes, you are the one I was referring to. I will tell the service guy what you said. I hope his machine is in inches! I assume the steering number should be at zero, right? I'm heading out in the next 10 minutes to leave to have it done, so if I don't reply back right away, that's why.

Caster is measured in degrees like you said. Keep it in the range you have mentioned or narrow it down for the tech to between 7.5 to 8 degrees. Just make sure that the caster is matched from left to right, you do not want any more than 1/8 degree difference. Front end only there is no caster adjustment on the rear.

Thanks Rick T! No, I don't know what my factory settings are right now. When I changed all 4 tires last year, the front and rear tires were worn a little more than normal on the inside edge. So, my toe-in might be off a little I'm guessing. I'll check that thread you pasted for me, thanks again
