Are there any benefits to running 335/30/18 (rear)? I ask because I'm looking at a Z06 which has been mini tubbed to fit 335.

The more rubber on the ground the better IMO. Be prepared to take a huge points hit if you're planning on doing any sort of time trial racing.

You'll have to run 315s up front to get any kind of neutral handling.

Of course, you don't have to run 335s in the rear.

Are you going to be running at MSR?

I run 18x335/30s on 18x13 in back and 18x305/30s on 18x12 up front

Besides tubing you may need spacers to fit the rim on the hub too.

On the street they trammel all over the place, way too ride for street use.

You wouldn't happen to be looking at the red former T1 car up in Canada, would you?

I disagree with the statement about "you`ll have to run 315`s up front to get any kind of neutral handling"
I run Toyo RA1`s 273/35-18 f w/335/30 r with proper corner balance and alignment.........the above combo drives very balanced!

I do agree that the more rubber the better, but a 275 f will work!

Yes, as soon as I buy a vette. I used to have a blown G35 that I raced there, but I sold it a few years ago. Since, my buddy bought a vette and I've fallen in love all over again.

GlenRoseFireFighter

No, but can you share more info?

VetteDrmr

Point made. I just know that with a streetable alignment my car understeers quite a bit with a 315/275 setup. 305/275 has a small amount of understeer, but I attribute that to overcooking my corner entry. The 315/275 will understeer both on corner entry and exit.

Now, on a track-only setup....

Have a good one,

I'm running 335/30/18 in back and 285/30/18 in front (hoosier R6). It keeps the proper diameters for the c5zo6 front and back. Also, if you look at hoosiers tire specs, the 285 tire has more tread width than the 295. My car is not tubbed at all and I use 5mm spacers in back. I think my car handles great .

I talked to CCW when I ordered my new wheels. He asked if I was running Texas World Speedway, if so then I may be careful on the transition to the banking, or raise the ride height a little to keep from bottoming.

If you run banked tracks camber settings are different then flat or normal road circuits.

jkittleson

What camber settings would you suggest for a banked track like Texas World?

undertaker

mine pushes with that same setup.......of course that lets you spend more time on the fun pedal to rotate the car!

AU N EGL

Depends on how elaborate you want to get.

-1 left side -0.5 right side was for Charlotte or Lowes Motors speedway and Daytona do to the extream banking.

I think I would start with
-2.0 front
-1.0 rear

Then change to normal road course settings

Normal road courses

-3.0 front

-2.0 rear

I believe a lot less than 1/3 of the 2.9mile lap at TWS is on the banking, the rest is traditional "flat track" road course "in field".
