Hey Folks-
Anybody running 17" TT2's with the C5 brake upgrade? Do they clear? How about the 18" wheels? Thanks!

Don't know YET but when I find out if they'll clear C6 Z06 calipers I'll let you know.:thumbsup: In the meantime, you can download a template on Kore3's website.

Nice, that's the swap I'd like to do. As far as the template, it won't help me much right now with no wheels! Are you using AFX spindles?

Yes and no. Haha. I'm planning on them...they haven't arrived yet. And since everything hinges on the spindles (no pun intended) I've decided to wait until I physically have them in my hand to make the rest of the purchases. The suspension IS planned out though. :thumbsup:


Oh...and you can either have a dealer use the template for you OR ask one of the guys running TTII's. I'm sure someone would help out 'round here.

If by C6 Z06 brakes you mean the 14" rotor w/6-piston radially mounted caliper then that would be a no for fitting in any 17" wheel, really. I believe 18" is a minimum with roughly
1-3/4" for caliper/spoke clearance.

17" TT2s will fit C5/C6 non-Z06 w/13" rotor -- with the appropriate spacer for the caliper/spoke clearance.

Caliper clearance on 17" TT2 is 7/8 of an inch-will not clear the big calipers without spacing.

I have used Kore3's template on my 17" TTII's and the short answer is none of the Kore3 stuff will fit without a spacer. Looks like the C6 Z51 setup might fit diameter wise but once again you need a spacer. I am thinking about doing the C4/C5 hybrid setup in order to clear without spacers.

Keep in mind guys, he was talking about the clearance on the 17" w/ the C5 set up. On the other hand, my plan was 18"/C6 Z06 set up.

So I guess another question would be, "Would EITHER Kore3 C5 or C6 Z06 set ups clear 18" Torque Thrust II's?":D

As I stated before, and Newstalgia stated after me, the caliper/spoke clearance needed for the C6 monoblock 6 piston radially mounted Z06 calipers is well over (1.75") the available caliper to spoke clearance that the TT2s afford (.75").
Unless the TT2 spoke clearance is different from diameter to diameter (doubtful) these will not fit the above without roughly a 1" to 1-1/8" spacer.

The TT2s would fit, 17s or 18s with a C6/C5 base caliper with the appropriate spacer, 1/8"-1/4" (whichever is available) 13" rotor max for the 17" TT2 wheel.

I have very similar spoke clearances on my wheels as the TT2s, with a 325mm rotor and C6 caliper, I require a 1/4" spacer for my application. Jon @ Driverzinc sourced me some hubcentric (wheel side) billet spacers that I would trust to autox on, for sure.
I personally would rather have the thicker C5 rotor than the thinner but a tad taller C4 rotor. My reasoning for this is the massive weights of my car and probability for warpage upon hard braking. Less of an issue for a weekend cruiser, though. Just my opinion. :beers:

I guess I missed that part. Hmmm, looks like I have more homework to do to make my wishlist come together. This saves me a step but adds another. Was hoping to have both but now not so sure.

Yup, that's what we did.

As a side note, this is exactly why NewGen Wheels exists. Classic designed wheels, but custom built to fit around modern brake updgrades, and in modern diameters, and widths. Yes, they are a little more money, but now you can run a classic designed wheel. :thumbsup:

Waiting patiently for more brushed 18/20 combos to pop up, Jon. ;)


Dan, do you have pics of your setup?

First link in my signature block is to my photobucket. Last link is my build thread over on Pro-Touring.

Found them after I posted. And...your calipers look very close to the spokes. Closer than I expected.

That is certainly something I have considered as well I just have a fear of those darned wheel spacers although the Hub Centric is the only way to go. With my chevelle weighing in at 3300lbs I doubt it weighs a ton more than a C4 but thicker rotors are better.

As the pads wear, the caliper will pull inboard a bit more. The pic was with brand new pads. Holding the caliper outboard I still have about 1/8" clearance... If the wheel and caliper heat expand more than that, I'll have a big problem :p (but probably not bigger than why they expanded..)

Your 'velle is certainly lighter than my 3800 lb beast... all iron BBC at its nose.

That aluminum LS1 does wonders. I was pretty happy the first time I weighed it.
