Drag Spindle Questions
Thinking about it...
So, are there any drawbacks, other than $$, associated with running drag spindles on a C5Z that will see more street use than track? I'm currently running 18/19 Forgestars, but in a quest to fit a 26" bias drag tire. I'm not liking any of the 16" wheel options that seem to be available. 15" wheels will certainly open up a bunch of tire options to me. That, and I've acquired a set of 15" Race Star Dark Stars if I go this way.
Are these REALLY a bolt on, or are other mods....clearance issues to contend with? Grinding calipers, control arm, etc...?

Yeah brakes have to be Non-Z, many use the GM Strange Fronts, but if you have them around or yours already have it the corvette base OEM brakes fit. as Gxpz06 said, depending on the wheel you install you may have to do some grinding on the lower control arm.

Wait... So you're saying that 15" wheels will NOT clear C5Z rear brakes? I was under the impression that C5 base and C5Z rear brake setups were the same...save the cooling ducts.

Oh, sorry on the c6 you for sure need non-Z / GS / ZR1 brakes. Not sure on the C5 to be honest. Quick look on http://www.gmpartsdirect.com/ will tell you for sure tho.

C5 base vs C5Z brakes does not matter. You might have to grind the caliper a little. I did not have to.
You most certainly will have to grind the lower control arm from the ball joint area to about 5-6" inboard due to the wheel hitting it.

Thank you. That's what I thought. Currently looking for the best deal on a set of drag spindles.
