I used tabs like the JEGS ones from Speedway to add a flex line to the rear discs I have -basically a TA setup with "front" metric calipers on it.

What did you do for a parking brake? Delete?

Delete! This is a race car.

Although Wilwood now has a rear disc setup using the metric caliper and a inside drum/rotos E brake setup.

Is this 11.6" rotor the biggest or best option money-wise for the rearends? Or is there a larger factory setup that can be fit? I have front and rear C5 Corvette calipers that I got off someone dirt cheap.

The 98 - 02 Camaro brakes are 12" rotors. For most applications a 17" wheel will be needed to clear the caliper.

Good to know, the Torque Thrust II in 15x8 almost fit when I installed my rear brakes, a spacer or caliper grinding would have been needed.

Has Anyone had any issues with the wheel not centering itself on
the axel flange after the rotor is installed? Everything bolts up just
fine, but I find I have a little play in the wheel when the lug nuts
are loose when the rotor is on and non when the wheel is mounted
without the axel.

It looks like the distance of the flange that is left is the same as the
pics on this forum. I'm using TA snowflakes and maybe camaro wheels fit different?

I've got a ton of pics posted here:
http://transamcountry.com/community/...?topic=50695.0

Somebody mentioned using concentric rings, has anyone tried this?
Not sure how to proceed.

What you are experiencing is normal, the very end of the hub is a little smaller than the base where the wheel used to sit. Most after market wheels are not hub centric, the lug nuts will center the wheel hold it tight provided they are not bottoming on the studs. If with the nuts tight the wheel is loose the studs are too long.

That's what i was hoping. The lug nuts do not bottom out but if I
loosen them there is about 1/8" of play where I can move the wheel.
Maybe I need some different lug nuts that fit tighter (inside the lug nut hole in the wheel)?
They are not the conical nuts that seat against the wheel, but rather act like a
sleeve and slide throught the wheel...

If the wheel is tight and the taper on the nuts match the taper on the wheel it should be fine. The hub centric rings in the Summit link are all plastic. Really not sure they would give me much piece of mind for supporting the wheel.

I think that is the issue I'm having..
My lug nuts and wheel are not tapered, they fit through the wheel
and use a washer to hold the wheel down. Not sure if the
centric ring would help center it or not...

Well apparently my lug nuts are not correct for my wheels. I never
noticed this as apparently the axle flange held the wheel centered.
When I got home I checked one of the lug nuts in the wheel and I
have as much play in the hole as I have slop in the wheel, so I have
the correct lug nuts ordered and will keep fingers crossed...
Thanks for the help, I'll post how it turns out

Not all lugs are correct for the wheels. My lug centric wheels have only about 0.010 clearance in the holes. Even the factory snowlfake wheels and lugnuts have 0.040 clearance and without being hubcentric the wheel can be offset. Especially if using 1/2" studs and 0.681 aftermarket lugnuts that are 0.020 smaller than the factory ones that are .700.
