I bet its other way around.

That's all about bling and who has capacity for the most credit card debt ;)

Stock is very capable with right mix of pads and fluid. These heavy weight rotors will accelerate slower and as many test have shown, improve face resistance ( heat capacity) but not stopping distance. Physics is a *****. When you get to endurance style events where mass matters, your car will be on a trailer, gutted interior without 15 airbags and probably 3-500lbs lighter and then stock rotors will still be up to the task.

It's another line on the forum signature, Errmagawd Essex bkk.

No one needs to change pads in a minute at the track - those things are near 800*F, you will let them cool off! You will compress the pistons back, both of which you don't want to do when they are scorching hot. Reality vs marketing lines they feed you -- hook, link and sinker.

They certainly help braking distance on every stop after the first, because they don't fade.

With brakes, it's the same IMHO. What's the application? (DD? Track? AutoX?) What's level of driver training/skill (aspirational? professional racing driver?) What's the best aftermarket brake system for the ST and are only the fronts required over a 4-corner system? "Depends!" There is no one-size-fits-all answer here.
That's the way I see it, too ... "Depends!"

At least we ST owners have got some good aftermarket brake choices. The Essex/AP BBK has the unique combination of features that I value.

Wilwood, Stoptech, or other BBKs have unique combinations of features that others obviously value. Great stuff.

In a perfect world I would hope that, given my investment, the Essex/AP kit would out-perform other big brake kits, but I'll never know. As long as it delivers on its own promises, I'm good.

It's an awesome kit for sure. Lots of top rally cars use the J-hook rotors. I expect you'll be able to beat the stuffing out of those brakes and they will keep coming back for more.

Now all you need to do is ask your tuner to turn off the safety throttle cut out so you can left-foot brake... :)

All the best,
Mark

cost was 800 bucks for the 6pot front replacements with ss lines for all corners with bp10 pads and Hawk HP+ rear pads on the stock rear calipers. 800.00

Then I moved to the BBK for all for corners. i paid 2500 shipped to my door and it comes with all 4.

They stop quicker and have better feel than the stock or the stock replacements I had before them. repeatability is awesome.

I also like that I have all 4 corners matchy matchy..

Thanks Mark - i'll let you know if they live up to their outstanding reputation at the track.

Loving Essex/AP BBK so far. Can't replicate that level of braking on the street (tune suggestion notwithstanding!).

Congrats kwiksilvr - I know you'll enjoy your BBK!

Awesome that Jeff and crew are supporting the ST also. I ran their kit on my BRZ and *loved* it on the track. Great stuff!

Biggest advantage really is consumables and weight savings. Consumables is huge, I made up at least half the kit cost in a year or so of track usage in just consumables.

Can't wait to hear Mueller Motorwerks' review of their Essex/AP Racing Competition Brake Kit once they finally hit the road courses with their track monster. Their build thread is impressive, to say the least.


So, I was able to weigh the stock setup. Stock rotor 22.5 lbs Stock loaded caliper 16.5 lbs Total: 39lbs AP kit information from AP Rotor 17.6 Caliper 4.8 Total 22.4 So a 16.6 lb (our stock caliper did have pads and residual brake fluid still inside of it so that will account for some difference) saving per corner. Not too shabby at all.

We do have a preliminary video review. We should have a more in-depth review up after some track time, we don't feel the autox that we did was a sufficient test of the braking performance to make any final judgments yet.
