Brembo: Shelby(s) vs Mach

[Prodigal]

What are the differences in the front brakes on the GT500 vs the M1? Both use Brembo calipers, are they the same? What about the rotors?

The GT500 has massive brakes, 16.5" up front, 14.6" in the rear.
The GT350 has 15.5" up front. 15" rear.
The M1 has 15" (nearly) up front, 13" rear.

Thanks. If I’m considering rotor upgrades anyways, is there any interchangeability to the Shelby units for my M1 or do I just need to stick with Steeda, GiroDisc and other aftermarket manufacturers?

None of them are interchangeable without changing the knuckles, calipers, rotors, pads, etc. I think the only thing that might be common is the hubs and even then, the wheel studs are different among the various trims (GT500, GT350R, GT350, M1, etc).

Keep in mind that most modern cars are traction limited brake systems, meaning the brakes aren't the limiting factor, the tire patch is. If you stand on the brakes, it'll slow to the point of activating the ABS system.

So larger brakes only really help for additional fade resistance and heat sink. You won't stop any faster, you'll just be able to stop harder in harsh, repetitive strings for longer (aka track use).

The M1 has the same brakes as the GT with PP1

Are you two on a mission to upset the M1 guys when they find out they have the GT MR iron knuckle rather than one of the nice aluminium 350, 350R or 500 Shelby variants … ?

Joking aside, internet pictures don’t really highlight the size differences too well, if you see them in real life it’s much more obvious

Who really cares when the braking performance of the M1 equals the GT350R? You can argue all you like.

You meant to say "when they found out they have GT with Tremec and some stickers ?"

lol

Braking performance is more than initial bite and stopping power. Swept area, total material weight and heat sink get a vote. It's like arguing that a single shot rifle is the same as a semi-auto with a C mag.

Just for some perspective, the GT500 rotors weigh over 40 lbs. The fact that they're ginormous means more surface area (for cooling) and also means they can absorb and store more thermal energy (specific) per degree of temperature rise. The 500 needs it as it's markedly heavier, but the point is, bigger brakes after you reach traction limits are to increase braking stamina and resist fading and performance drops associated with repetitive and extended harsh use (aka track sessions).

At least for the fronts, a few companies make adapters that bolt onto the GT knuckle and accept Shelby calipers so you don't have to change the whole thing. I don't know of any for the rear, but these make swapping to Shelby calipers super easy.

My google fu is weak. Gotta name?

They make 2 different adapter kits, one to use PP 15" rotors with the Shelby calipers and one to use the actual 15.5" Shelby rotors. I went with the PP option and it works perfect with my original PP rotors. The only new things I had to get were the calipers, pads and said adapter kit.

I love my GT with stickers.

You'd be better served cutting the unsprung weight and going with a two piece rotor and PP Brembo's than you would with GT350/500 brakes.
