I believe the OP may be mistakenly assuming that the Stillen AP = Essex AP.
To clarify, we have the Essex "Sprint" kit on our car |

The Stillen and 6-pot Essex/AP kits are "street systems" with dust shields and I think aluminum pistons. I don't understand how Stillen does the rear e-brake, maybe they don't use an e-brake?
The Essex Sprint and Endurance systems are race calipers, stainless pistons, no dust shields. The Essex website has very good blogs on the weight differences from stock. The Essex 6 pot system is so big that you probably couldn't melt the dust seals. I know crap about Stoptech. Any proper 12x1.25" curved vane rotor with a 4 piston caliper and some aggressive pads will stop a 650hp, 3300 lb car very effectively. Its a decision about how often you want to change/turn rotors. I race a 425hp/3000lb w/driver&gas car with basically the same size brakes as a stock FRS/BRZ. It will stop fine, but I have to replace rotors after a three 25 minute races at hard braking tracks. That sucks but I have to abide by sanctioning body rules for my class.

The stoptech kit is the more "street friendly" option with dustboots and street pads included. However for a more track oriented car the Essex AP racing kits will save you a little money while being a serious kit for a track car. Still streetable for sure, just a little more maintenance.
This is assuming you're talking about the Essex ap race kits. I don't know much about the ap street kits. Stoptech always makes a great kit, so you really can't go wrong here. Pad selection is great with both. It just for your needs...street friendliness might not be worth the slightly extra cost. And weight. Up to you. Also, I wouldn't worry about a rear kit. - Andrew |

I'm having the same dilema... but for me it's between AP and Wilwood. AP is arguably the better of the two, but it's also more money, and doesn't have a rear solution yet for the Sprint series. If AP had a rear kit that matched the balance of the stock FRS, I think that would be my first choice. The new kit AP just released isn't as track focused for me, a great kit for the street and for show, but it weighs more, and you'd need 18" wheels.
The Wilwood kit seems perfect for me. Daily driver, some track (7-8 times a year), easy pad change on track day, lots of pad choice, and a great reputation with my racing friends. When speaking with people using Wilwoods, they are always very enthusiastic with their recommendation. I haven't heard ANY complaints. Though the prices for the Wilwoods haven't been released, historicaly they have been very well priced. ATM, it's Wilwood for me, but I'll be following this thread. (I should note however, that my expertise on this subject is from about 100 hours of online research, and speaking with people using said products. Not 100 personal laps of research on the track, so take it with a grain of salt.) That's my 2 cents

Yeah, the one good thing about the 6 piston AP kit from Essex with the 4? Piston rear setup (I think they have rears for that one, correct me if I'm wrong. IIRC it's mucho dinero) is that there is SO much thermal mass that melting the dust shields will likely be a very, very remote possibility.
As far as track performance, it's my understanding that the stock rear brakes with good pads and fluid are more than sufficient. They just aren't as pretty as a nice monoblock. I think you'd have to be running slicks and a lot of HP to make the rears be the limiting factor. @gmookher -is your main focus DD or track? @JRitt - what is your opinion on daily driving the CP8350 calipers? I've gotten varying opinions on the need for dustboots. Cheers Nathan |

If your car sees road salt, forget any of the Essex race kits.
@SubieNate the dust boots aren't the important part of daily driving; see what I said above. You will wreck these calipers with road salt so in that fashion they can not be daily driven on a car that sees winter. |
