What wheels you fitting them with?

 

[justinsstang]

Even the 6-piston brembos... I mean, for $250 each new, that seems like a steal. That's what I'd be trying to make fit haha.

Although, the 4 pistons would be a huge upgrade from what I have. Those suckers are probably very heavy though. Wondering the weight difference between the 11-14 non-brembo brakes and the 4 piston S550

 

[v6tungsten]

I have 20x9 Shelby Razor with 24mm offset and 18" GT supercar wheels with about 35mm offset with spacers.

yea the 6 piston are also a steal at that price but you woudl have to run 19" or 20" minimum. I wouldnt think to many 18" would fit with 15" rotors.

 

[v6tungsten]

11.5 by my scale.
Looks like the caliper will sit about 4.75" out from mount

The 6 pistons require a gt500 or equivalent master cylinder though right?

 

[GallopingFord]

What brake lines are needed for a S197 to run these? Going to push a colleague into doing this swap. lol

At this point any stainless line should fit. I'll see if I have an oem line this weekend to confirm oem fitment.

Not required but I've heard of a few people swapping the ABS module other than that you will find that a lot of guys are running 6 pot Brembos with the GT master cylinder and ABS module.

Thanks I'll be looking forward to what you have to say.

 

[Black Bullitt]

Subbing. May do this instead of my Brembos. hmmm

fitment

fitment issues I found. rotor doesn't site centered in caliper, 2015 caliper is about 1/4 farther out than gt500 caliper. my rotor rubbed on the caliper when turning. I didnt have the wheel on but did tighten a few lug nuts on the rotor.

18x9 gt wheel fit thought. Shelby 20x9 rub on caliper

I'll leave it to the experts to see if something is different with my car but I don't think I would run them as they fit.

Perhaps a small spacer under the rotor hat?

 

[v6tungsten]

Wrong way rotor needs to be pushed in or caliper pushed out maybe 1 to 3 mm to cetera everything.

Again I have after market ebay rotors...so I will wait on someone with oem parts.

Also my normal 20x9 wheels are already 24mm offset so can't go 5mm more or they would be poking out

 

[v6tungsten]

You could always run spacers between the caliper and mount. They come in .015 and larger to space out the caliper.

Just wont work with my 20"wheels summer wheels but would be fine with the 18"

 

[BIGCHRISS197]

Would you feel comfortable putting a spacer under the caliper?

 

[v6tungsten]

Sure, as long as the spacer fit correctly. I actually think wilwood calipers get shimmed all the time.

I'll let experts chime in though as I have no experience with shimming a caliper.
