My 6 year FC project

What's the reason for the different piston diameters in the caliper?

Great build, I love to see people do everything and do it correctly. This is going to be an amazing car when it's done.

Basically the pistons are tapered in size from front to rear (they get larger towards the rear). This is to compensate for incandescent material buildup on the pad that typically gets pushed to the rear - the larger rear piston will be able to compress better to overcome this. It gets more unified braking and pad wear.

The only real downside to this setup is the lug mount (which is factory as well) since it doesn't allow an easy change in rotor size since you'll have to create an entire new bracket every time you want to go up or down a rotor size.

Still though - these should prove to be great at bringing my best to a hault in a hurry.

Thanks... its a very very slow process, lol. Right now i'm spending more time buying parts and working in the garage than online, which is probably a good thing, lol.

Just get some good pads on 'em. The rotor's and cali's are incredible. Repeated 130-60 braking for 20 minute sessions and zero fade. I should be able to overpower the dragon this year.
