i have APs.... i think the install was involved.... it took me from 6am till 7pm, but im over the top with things..... The kit itself slots in place like o.E parts, the Rear was a pain in the ass and the front rotor shield needed heavy cutting, again it took ages to do it nearly and i brought really good quality tin snips, they were blunt in no time, i used an angle grinder with a cutting wheel!!
my kit has the larger m3 rotors, fit, finish and quality was absolutely second to none, my kit has the optional enamel paint finish which still looks new even after some serious heat cycles..... The Front AP calipers are HUGE.... be sure you have decent spacing on the front wheels, or a lowish offset, an ET 32 on a 8.5" rim gives about 3mm clearance, and CSL spoke offers decent clearance. Also take care with the Anti rattle pieces, every single AP install ive seen have them in the wrong orientation specifically the back!! You can choose from Fully floating or fixed.... I have APf404 Brake pads for everyday and pagids for track use, you can swap pads in minutes once the wheel is off!! good luck and enjoy!! BTW the instructions are Awesome! and very very detailed!!! i studied them for around 2 night before the install and thing went like clockwork, i can say however it was a REALLY enjoyable process..... id love to do it again but without the time constraints, spread over 2 days this would be a really nice DIY.

Since your rear rotors are not floating, do you find issues on track? You track your car a lot so curious why you didn't get floating rears?

Beedub, what model numbers? I'm only seeing one model for front and rear on AP's website.

^ What you have, I guess. Didn't know AP made more than one application for our cars.

Still think the 6 pot front is completely overkill on this car, 4/4 would be ideal IMO.

I think the context of "floating" disc is not what I'm articulating well (not that i really care). A track buddy recent fried his stock WRX brakes with hawk pads and moved onto AP with "full floating discs" in the sense that when compared to some other BBK they have some movement which as a result have an audible noise in certain conditions i.e move on the carriers creating chatter/rattle. I guess one could argue the definition of full/true floating based on the degree of free movement that is axial or radial to center in the caliper when braking.

100% stand by that..... 4/4 would save a huge chunk of weight as well ;-) even the 6 pot caliper is lighter than stock.....

Not sure why yours makes noise Bill :/
Yours is a GT Monoblock 6/4 setup like mine right? Yours is way newer too. Surprised it's got any sound other than "wow! Love these brakes!" I have Ferodo DS2500 pads on mine. Works well both on the street and at the track |

The fronts still take a significantly higher braking load. If you have 4 pots they should still be setup differently f/r. Also the mass of the 6 pot is a bigger heat sink for the extra heat load. ....besides, they look the part

Sigh.
Forum "expert" or not, I would not go 4 front, 4 rear for performance reasons UNLESS the piston sizes are proportional. Meaning, the 4 pistons in the rear MUST be smaller than the 4 piston in the front by the same ratio or close to the same ratio as the stock bias. Not saying a 4/4 will immediately put you in a tire wall or lock the rear up when you brush the brakes, but it most CERTAINLY will decrease the actual effectiveness of the system. It's akin to putting on track compounds in the rear and street pads in the front. Sure, I can probably drive it on track and still have a good time, but it's no where near the ideal solution. Oh, by the way, I thought I've earned enough street cred here to be above the "forum expert" snarky comments. Obviously I am wrong.

Full floating means that the disc is free to move about in transverse direction and that causes noise to some extent. And that's what your friend has. |

^ this.
Yes there is a difference in semi vs full floating rotors. "Street rotors use a curved drive pin washer to add tension to the hat assembly, reducing rattle. Race applications use a flat washer that allows full freedom of movement between hat and friction ring."

i cant be bothered to get into a debate over how many pistons is better just giving my opinion from experience, but..... i can say.... dont be so offended, man the hell up. no-one is questioning your "street Cred".

Here's a white paper on brake bias from stoptech. I'm definitely no expert, but this backs up everything the hack is saying (and so far everything he's said has checked out, I've learnt a lot from his threads). I know things get heated because we all have strong opinions, but there's always room to learn something new
