I have a C6 w/Z51 springs, Koni FSD shocks and Pfadt street swaybars and stock GY F1 SC runflats which will be replaced with Michelin Pilot Sport PS2s soon. My car is strictly street driven (no autocross or road racing, and not much highway either). I'm looking for more cornering grip and better steering response. What specs would you guys recommend for me? I drive pretty agressively and the outside of my front tires is wearing much faster than the inside (I thought maybe my factory alignment was off but the camber is actually around the -0.45 camber spec) so I'm thinking of increasing the negative camber to -1.0. Too much? I believe factory specs for toe are +0.10 in the front and 0.00 in the rear. What should I get the toe set at if I want good steering response without compromising straight line stability too much?

Thanks!

I do run my car at the track (road courses). At the recommendation of a more experienced C6 racer...my car is setup virtually level and these are the alignment specs I used:

FRONT:
-1 DEGREE NEGATIVE CAMBER
6 DEGREE CASTER
0 TO 1/8 TOE-IN
REAR:
-3/4 DEGREE NEGATIVE CAMBER
1/8 TOE-IN

This seems to work fine on the street as well.

 

Close to same specs I set mine too, very happy with the results and tirewear so far.

 

Does anyone know what the standard alignment specs are?

 

These are for the coupe and the convertible

The Z06 goes to a -1.0 on the front camber

1 degree is definitely not too much, but you probably don't need much more than that either.

I'm running a Z51 with Z06 rear bar and PS2s, stock shocks (for now).

I find that the PS2s like a bit more pressure than the GYs, I run about 36 front / 33 rear (cold).

I increased the camber on the stock tires a couple of times, ended up running -1.3 front / -0.9 rear and still had more wear on the outside than the inside. I've backed off a bit to about -1.0 front / -0.75 rear on the PS2s, which seem to do a better job of keeping a flat footprint.

Reducing caster some from the rather high factory value helps steering sensitivity quite a bit. You may need to reduce it a bit anyway to get enough negative camber. I'm at about 6.5 but likely to drop it another 0.5 or so soon.

There seem to be many different opinions on toe, but you don't want much. A little bit goes a long way with these cars. A bit of toe out front may give a little faster turn-in, but a bit in may be more comfortable to drive. I think the combination of front toe-in and reducing caster gives me the best combination.

In any case, about 1/2 as much toe in the opposite direction on the rear seems to work well for me. I'm running about 0.1 degree in front / 0.5 degree out rear (per side).

Tread wear on the PS2s with these settings is quite even, and temps are fairly even, with the insides just a little warmer than the outside after a "spirited" run down a favourite road
