Wheel/Brake Clearance

[KatoS197]

Unfortunately, brakes is one of my weaker areas in knowledge, so this may come across as "duh".

AM's FRPP Brembo 6-Piston Brake Upgrade Kit

Front rotors are 15" but obviously the calipers themselves add to the space inside the wheel.

Will these front rotors/calipers be able to clear 18" GT500 Wheels?

If you read the complete details on the brakes it says 19"wheels or larger.

Toooooooootally didn't even see that.

Those brakes will fit with a few 18's. IDK which ones though.

I think forgestars and welds fit with the right offset as 18's. I thought I read somewhere that any 18" that will fit over 4 pot brembos will fit 6 pot too

Might be true if the rotor isn't larger. I tried my 18x10" SVE Drifts over a set of the 15" Brembo 6-pot, no go on those.

There's some limited info on wheel/brake clearance in this thread

I'll tell you right now that I can barely get a rag between my factory 18's and the 4 piston brembo's on my car. I don't see any way you could fit the 6 piston calipers in the same spot.

I have the 4 pot GT500 brembos and 18x10 forgestar F14s, and there is decent clearance. Not sure how "tall" the 6 piston calipers are, though. it would be cloooooooose!

Thanks for the thread share. Definitely found the info I was looking for. Got a quote from my Parts Dept. on the '07 GT500 Brembo Upgrade Kit and I'll probably be looking for take-offs on eBay or something when the time is right.

I've come to the conclusion that for my once-in-a-blue-moon track day/daily-driver use of my car, I'll either go for slotted rotors and upgraded pads or spring for the 4-piston calipers and 14" rotors. Possibly Baer instead of SVT.

I have take off 4P Brembos with stock 18" Bullitts. You can barely slide a sheet of paper between the caliper and the wheel. I don't think the 6P are gonna go under 18s.

Holy shit that's close. Lol. Well I would think I'll be ok on clearance doing 4P take-offs with the GT500 wheels I'm running.

I didn't even think that the bullitts would bolt up with the brembos at all. A 1/2" or maybe even a 3/8" spacer would probably give sufficient clearance for driving.

7/8s here. Almost no room between the spokes either.

These are from GallopingFord's build thread.

I knew that a 7/8" or 1" spacer got it done but I didn't think that it would physically bolt on without a spacer...

 

[Paul.]

Pffft. Forget the 18s, get 20s!! Plenty of clearance!

 

[GallopingFord]

The 2007-2009 GT500 wheels are probably one of the most clearanced 18" wheel, but I'm not sure if the 6-piston would fit.

I do know that the Enkei PF01 18X9.5 will fit them though with a 1/8" spacer. (see here)

Yep and I'll tell you one thing even with putting one of these wheels into a curb at 35 mph, the brake caliper never contacted the wheel. Literally almost no clearance at all, but with quality spacers zero issues.
