Are there any 18"x9" wheels that will fit the new GT500 front brakes. Thinking of upgrading but run 18" slicks on track
5 DOT 0 said:It was suggested to me that the 6 piston GT 500 brakes will only provide a bit more cooling with the larger rotor and not necessarily more stopping power. The 302R/S BBS wheels should clear those calipers. Call Rehagan Racing and talk with them to verify.
Read post #5.[email protected] said:Anyone ever verify 18" BBS wheels from FRPP fit? or any other 18"
I have 13 GT500 brakes on my boss and need to pick up a set of track wheels.
The stock brembos with carbotech XP12s performed well, but were running about 600F around AMP, I would like a little more cushion, as I could feel them fade a little if I ran it hard for several laps. This was still on a stock tire.
As this uses a 380mm disc, most likely, this kit would require a wheel 4"
larger than the disc, so a 19" wheel would be used. However, some wheels
have much more clearance than others and an 18" wheel may clear, but it will
be tight if it does.
I've attached the wheel clearance diagram for this kit. You may be able to
have Summit check it against their wheel to verify it clears.
Our kit needs 220.7 x 2 = 441.4mm in the barrel. That's 17 3/8" overall, so
not likely to find an 18" wheel with that much clearance inside the barrel.
The GT500 uses a 19 to clear it's larger Brembo brakes and the Boss 302 has
an optional 19" wheel available, so running a 19 would allow the use of our
kit and still be in the character of the car.
NFSBOSS said:Darren, I'm not familiar with Brembos GR-R calipers but the 302S and 302R BBS wheels work with the race calipers which are larger than the calipers on our cars. That's what they were designed for and there are no fitment issues although you may need a small spacer for the front. The best thing to do is call one of the race shops like Rehagan and talk to them.

pufferfish said:Steve, I have been working with Team Dynamics on an 18x10 wheel for the Mustangs. My requirements were: 1) ford hub diameter, 2) had to use stock lug nuts, 3) the perfect offset for the S197, 4) must be strong enough for street and track duty, 5) must clear the Stoptech 15" 6-pot BBK (which take up the same space as the '13 GT500), 6) reasonably priced. Well, after some time, we have worked out the details and they are being manufactured now. They anticipate having them in the US and ready to ship out in March. These are based on their Pro Race 1.3 line. They will be offered in black and hi def silver. No official weight yet, but it should be around 24.5lbs. Not the lightest, but again, they are strong enough for torn up city streets. Pricing will be set at $310 each. I will list them on the site once i have confirmation of their arrival.
