AP Racing 6-piston 14.25" rotors on stock 18's?

zfever

I have the base model with the non-Sport brakes and I want to upgrade them. Even a light amount of spirited driving (and associated stopping) is enough to induce fade. I would not trust my brakes on any track event.

I'm open to the idea that maybe I don't need the AP racing kit, but I definitely want to upgrade them and I want to do it once. I don't want to get to the track and decide I should have spent another $2k in the first place and then have to pony up for another whole set of brakes.

I did print out the template for the 6-piston AP Racing kit and pulled one of my wheels off and it definitely would rub, so those are out unless I get new wheels.

So I'm thinking about getting the 4-piston front and rears unless there is a compelling reason to get something else?

a used set of akebonos, good pads, good fluid, and new wheel/tires is the way to go

a "big brake kit" is utterly useless on crappy rubber

4 piston rears are not necessary. The sport 2piston kit is beyond enough for the weight balance of the car.

a 4 piston kit in the front is honestly enough if you go with the right pads and tires.


The most ideal/affordable kit would be just the sport package. Next up would be a stoptech St40 or str40 (if you can find it for a good deal), with the sport caliper and rotor in the rear. I'd spend as little as possible on this and save for a larger wheel and tire setup - At the very minimum 245 squared on 18x8.5 wheels.

Okay, so you think something like the Z1 sport brake kit? https://www.z1motorsports.com/brakes...ar-p-4296.html

I can do that for around $3k for both the front and rear with the 2-piece rotors. That's basically $2k less than I was budgeting, so I guess I could get some new wheels / rubber like so many people are recommending.

Yep. 2 piece slotted rotors, Motul 600 brake fluid, SS brake lines, Carbotec or other good pads. This is about $2,700 on the page you posted

I went sprinkle slotted on mine from Z1, Motul 600, EBC Redstuff, SS Lines from Z1; Then sat there and made sure the dealership flushed them out really good.

best part is they get even better and better the more you heat them up! Have yet to be disappointed when pushing them on public roads.

First car I've had in my life that finally has brakes that don't suck:

i have the kit in the first link. yes it fits under the stock 18"s but only with a 20mm spacer. I now have the PF01 18x9.5 upfront wit no spacer, the wheel just clears the caliper, i cant even fit a wheel weight in between the caliper and the wheel.

Thanks for the information. I ended up going with the Akebono sport brakes, stainless steel lines, 2-piece sprinkle slotted rotors, and Posi-Quiet ceramic pads (will grab a set of Carbotech's once I figure out which track events I'm going to do). If I ever decide these aren't enough it's good to know that kit will fit on the stock 18's with a spacer.

Thanks also to everyone who pointed me in the right direction with regard to wheels and tires.

My plan is to get a set of either RPF1's or PF01's in 18x10 (front) and 18x11 (back) with some sticky summer tires. If it snows here (sometimes happens in Dallas), I'll can always swap the stock 18's back on with my existing all-season tires.

Yes the rear bias sucks! Even when people run softer rear pads and do an ABS delete with a proportioning valve and turn it all the to the front, the rear bias still sucks. Don't go big back there. Rear Akebono is plenty with a softer pad.
