17" inner wheel diameters
Posted 24 January 2011 - 12:34 PM
Am considering a big brake conversion which I know fits within the 17" Mag wheels but I just want to confirm it will fit inside the AWI 17" wheels that I have on my GT V8 at the mo...
Does anybody have an idea of inner wheel diameters for these two..?

I don't think you'll fit a bigger brake than a 328mm...
from my Brembo brake project here:

THe caliper clearance is different that the gap around the rotor. The rotor has space for 25mm, however the caliper has only a few mm of clearance.
The offset shown is a 2x4 so ~1.5" from the backside of the wheel, which corresponds to about the distance from the wheel mounting surface back to where the rotors mount behind the hub on an SE like mine.
The V8, which Gary has, has a rotor mounted to a hat on the front side of the hub, so immediately behind the wheel mounting surface. In otherwords, his rotor will be even closer to the plane of the spokes and the thickest part of the wheel rim. He will probably have less than or equal to the same clearance that I show above.
It will not fit larger than a 328mm rotor (330mm AP max).
I will say that the AWI's have the most caliper clearance of all stock Esprit wheels!
btw, these are 328mm Champ Car brakes (8 piston caliper) in a Futura Modular wheel.
The 3 piece wheels have a forged rim that has a very thin cross section, but the center section spokes are closer to the caliper than the AWI's.
My Brembos and these Champ Car Brembos are designed to fit in a 15" forged rim, and they barely fit in a 17" cast rim.

My setup is 328x35mm front, 72 vane vented, aluminum hat, floating rotor, 4 piston NASCAR short track monoblock caliper with vented titanium pistons.
One of those calipers was incorrect, I had it swapped for a correct config (if you are looking closely)
The rear is 313mmx25.4mm, vented, aluminum hat, fixed rotor, 4 piston bolted NASCAR short track aluminum caliper with vented titanium pistons.
The pads are a soft compound NASCAR race pad (1" thick each in the front, pad only, not including backing plate)
And I have to use a separate parking caliper like the Sport 300 / X180-R. I have either a Wilwood spot caliper (very light) or I can use the Esprit/Elise rear brembo caliper (heavy).
