Race Wheel Studs
This may be a fairly uninformed question, but how much longer wheel studs do most people run than stock for the track?
The reason I ask is that I'm contemplating using dedicated track tires next season and know most use longer studs. I'm also looking into some spacers for street driving purely for asthetics. Maybe I could find a happy medium.
Thanks in advance!

Could I see a shot of:
1) The studs with lugs on your spacered rear wheel.
2) A close up of the lugs you use. Are they silver or yellowish?

Kodiaks, which are a popular wheel in SCCA T1, require longer wheel studs. I run CCWs, 17x10 front and 17x11 rear with stock wheel bearings and studs. I replace my wheel bearings and studs about annually.

The delphi cartridge bearing for the C5/6 will easily accept the ARP p/n 100-7704, 1/2 x 20 x 3.470 uhl wheel stud.
A simple drill through to clean the press knurl (of approx 0.060"), then drill guide diameter for 1/2" (drill 29/64") and then tap 1/2 x 20.
This not only makes continually replaceable, but the other available knrul diameters do not really fit past the wheel bearing/wheel speed sensor cartridge. The 0.568, 0.618, 0.625 and the 0.680 knurl fastners have a hard time making it past the bearing assembly on its way to the flange...... not to forget to mention, after a replacement or two, the knurl interfearence fit just goes away.

The studs themselves are light brass colored. Depending on the light sometimes they look silver / steel colored
dont have a close up. Look at summitracing.com

You said you run a 0.850 spacer, how does that work when the ARP stud only gives you an extra 0.5 inch over stock? I assume the foot of the wheel you run is thinner? Just trying to make sure I have a grasp on all this.

front CCW is thinner than rear by maybe 50% just a guess. No spacer in rear. CCW makes nice spacers and he may know what you need exactly. Your spring rate will change as you space the wheels out. How big of a rush are you in? I will have it apart next weekend.

No super big rush here. The spring rate/handling change shouldn't bother me since spacers are just an asthetic choice for me. I'm stil trying to guess what spacer I need to set the wheels flush with the fenders.
