I posted this on the other forum too, Pfadt Racing Website, the Performance Street setting is what you want...

The "performance street" alignment suggested on Pafdt's web site is not what the OP needs.

He asked about normal street driving and maximum treadlife. A performance street alignment will not provide that.

Before we can suggest an alignment, we need to know if this 06 Convertible is a Z51 or not.

[Donpat]

It is not a Z51. Thanks

For Maximum Tire Ware I set up C5's and C6's about the same depending the roads it's driven on.
I got 55,000+ miles out of the first set of Kumho ASX All Seasons on my 03,Looks like I'll be getting about the same on the second set!

Lt Front 0* Cam,6.5* Caster
Rt Front 0* Cam,6.6*-6.7* Caster : Depending crown of roads it's driven on.
Toe Front 1/32 in.
Lt Rear 0* Cam
Rt Rear 0* Cam
Toe Rear 0-1/64

The car will steer easier than factory settings.
WARNING!~! These settings WILL make the car a handful in excess of 125-135 MPH!~!!!

If the car feels too light in the front after alignment,You can take the front toe in up to 3/32 and it will make feel a little heavier!

Happy Motoring!

Junk's numbers are a good place to start and then, after that, I'd watch the tire wear then adjust pressures and camber accordingly.

Forgot to mention,I run 34Lbs Front,29Lbs Rear. I get a nice flat uniform tread ware!

For all those people who have requested a good alignment spec from me ,I've had to work though some issues and haven't been around .The spec that junkie has given is basically what I use and I recommend it .The only thing I'd take exception to is the speed range ,the C6 doesn't get funky until ya hit about 140-150

If you live in the snow country with pot holes consider an alignment every year or so ,it's not that expensive .

How different would the specs be for a Grand Sport Coupe?

If best tread life is the goal, the numbers given above are a good start be it a C5, C6 base or C6 GS.

Good stuff

Thanks

I can easily give up the last two percent of grip for better tire wear.

After taking in the specs off of several of the sites suggested earlier this year on the CAC, the alignment tech I have used for years ended up with these numbers for my 10 GS Coupe.

Front Caster Left = 7.64* Initial was 7.98
Front Caster Right = 7.75* 8.10

Front Camber Left = -1.17 Initial was -1.16
Front Camber Right = -1.22 -1.27

Front Toe Left = -0.01 Initial was 0.16
Front Toe Right = -0.01 0.21

Rear Camber Left = -0.90 Initial was -0.87
Rear Camber Right = -0.76 -0.81

Rear Toe Left = .00 Initial was -0.15
Rear Toe Right = .00 -0.14


The car tracks well at speed with very little tendency to wander but I have only run about a 1000 miles on the tires since the realignment. After 4K miles they had been showing inside wear. Nitto Invo's.....

You didn't say what the duty-cycle of your 10 GS Coupe might be. If you're a track rat and replace tires frequently, that's a good street/track alignment. If you're a street driver only and you seldom drive aggressively, with -1.17 and -1.22 in the front and -0.9 and -0.7 in the rear, your car will likely wear out the inside of both its front tires before other parts of the fronts and the rears are worn.

It'll probly scallop the insides too,give them another 4000 miles and he'll have a beautiful set of "Rumble Craps"!~!!

[Hib Halverson]

"Rumble Crap"??

Hmmm....

I looked at the tires on those sanitation containers for automated refuse collection programs and that name was embossed on the sidewalls.

Also, heard the Rumble Crap "GT Super-S" is OE in the new Viper.

Maybe that's why the ZR-1 cleaned its clock at Laguna Seca in that recent magazine test.
