it helps but its still a little mushy.

Okay, so when do you actually NEED 6 piston calipers?

yeah 4 pistons are prolly plenty fine

ok, its like this. If you have an S4 you'll need an S5 booster to go to a 929 MC. If you have an S5 you can go directly to a 929 MC. The piston in the stock S4 master cylinder is 7/8", S5 and Fd are 15/16", 929 is 1" which is pretty decent even in terms of an aftermarket unit.



I've done a kit with the same calipers on a different car with a 12.6" rotor and it fit under 17s, this time its a 2 piece rotor so i'm going to 13" its only a 1/5th of an inch difference in wheel clearance so it should fit for most people. My kit will be front only to start but i will also offer a carrier to relocate the rear caliper further out on a slightly larger than stock 2pc rotor as well. I have a wilwood proportioning valve on my setup and i suggest it for any big brake kit also.

6 pistion kind of seem like overkill to me.. will Fd calipers and rotors fit an FCS5?

easy answer is no, difficult answer is yes but not any easier than going to anything else.

Here's a news flash...the FC already has amazing brakes.

personally i think my four piston calipers with a rebuild, hawk HP pads, and cross drilled and slotted rotors has plenty "knock ur fillings out of your teeth" stopping power, and its def less than a big brake kit

FD rotors and Skyline Type M calipers will suposedly bolt right up to the FC, but good luck finding the Typm M calipers.



Now does anyone make a 13" brake kit for the FD that doesn't cost over 2k...
