Glad the brakes are working so well for you JSC, and congrats on the event podiums!
Why is the Essex/AP Racing BBK better than STI OEM Brembo's?

Are you able to make some sort of comparison between the Brembos and this AP Racing kit?
You ask, "But why wouldn't I just buy a used set of brakes from the last generation of STI and put them on my WRX?" There is a laundry list of reasons. Based on everything we learned during development and testing, our system offers the following advantages over the OEM STI brake system:
- Roughly 6-7 lbs. unsprung weight reduction from both front corners of the car, for an approximate unsprung weight savings of nearly 15 lbs. from the nose of your car!
- Incredible array of inexpensive race pad options at prices that are consistently $100 lower per set than the OEM STI pad shape. The pads in our calipers are 20mm thick and large enough to handle typical lapping/race session
- Mitigation of pad knockback due to 4lb. anti-knockback springs in the calipers
- Less chance of damaging bleed screws or crossover tubes when changing wheels due to built-in protection
- Caliper finish that is more resistant to wear and deterioration during heavy track use (no Brownbo's)
- Stainless steel caliper hardware for a long caliper service life under frequent pad change conditions
- High temperature, low drag seals that will hold up to track temps better than OEM components= less rebuilding and longer service life
- No dust boots to burn up and make a big mess
- Simple pad change with one bolt and no spring clips (rather than tapping out the pins on the OEM Brembo's)
- Extremely compact package for superior wheel fitment
- Stainless steel pistons that keep heat out of your brake fluid to resist fluid fade during extended track sessions
- Lifetime professional caliper rebuilding support by Essex (at a fee)- pull off your calipers, send them to us, we clean, inspect, and rebuild them
- High airflow, heavy duty, 70 vane AP Racing J Hook brake discs that are over 4 lbs. lighter than the OEM STI units, available at an extremely competitive replacement price ($250 per iron disc).
- AP Racing J Hook slot design that gives more pad bite/feel, and distributes heat evenly throughout the disc
- Disc metallurgy specifically designed to handle the temps typically seen on track offers a long service life
- Highest quality, Spiegler stainless steel brake line with clear sheath that reduces compliance over OEM rubber design.
The list above shows the technical superiority of our Competition BBK vs. an OEM STI brake system, but a quick analysis of the economics of the situation make the choice even clearer. Below are the approximate costs to completely revitalize an OEM STI front brake system, using high quality OEM components:
Powder coat calipers= $100
New Brembo seals & dust boots= $100
New caliper pistons= $200
New brake lines= $85
New discs= $150 (bare bones…plain face, pillar vane…if you want a high-spec disc this number will be higher)
New race pads= $300
That assumes you’re doing all of the labor to disassemble and rebuild everything yourself. Also don’t forget that this will all take time, which is a valuable commodity to many of us with families, other hobbies, etc. At the end of the day you’ll still have a used brake system that may have fatigued calipers (which leads to pad taper), heavy components, expensive replacement pads, etc.
The initial cost of rebuilding tired OEM parts will get you nearly half way towards buying a top-of-the-line, brand new AP Racing competition brake system, with all of the benefits shown above. If you go through 5 sets of front brake pads in one season and save an average of $100 per pad set (which you will with our kit), that’s $1,000 in pad savings alone over two seasons! At that point the cost difference between a used road brake system and a brand new optimized racing system is nearly the same.
Due to their superior quality and storied racing pedigree, AP Racing brakes also retain strong residual value. AP Racing is one of the most sought after brands in the racing world. While many components fetch only a fraction of their retail price on the used market, AP Racing products hold strong resale value. That means you won’t be flushing your investment down the drain when moving to your next track toy.

The article was originally written for the FT86 market, but all of the points hold true for the WRX as well.
Which would you rather start with...Hmmmm...?
OEM Brembo's after some serious track abuse
AP Racing CP8350 specially designed for Essex
Yah, yah…Now Prove It!
Below are some customer comments on brake kit vs. OEM Brembo's:
"I'd recommend this brake kit to a friend without question, and several have already taken the leap. A serious upgrade from the Brembo's. No paint fade, not screws to break off, no super expensive pads, no damn dust boots (I mean debris), runs cooler with just a 2 inch duct, Super easy to maintain, Super consistent and reliable pedal = WIN
, and one of the best performing rotors I've tested.
And the most important part, SUPERIOR customer service. It's not some retail store that sells parts, it's the actual racers and engineers you deal with when on the phone." -Balrok (Lancer Evo IX)
”Miles ahead of the OEM Brembo setup on an Evo. I can go all weekend without touching the brakes.
Just keep a check on pad wear and rotors, and worry about driving better instead of fooling with bleeding and fiddling with brakes." -Jim (Lancer Evo IX)
"I have had a Brembo kit and factory Brembo brakes before, and I believe these AP Racing kits are much higher quality.
I feel AP Racing is more enthusiast oriented, which shows in their designs." Chad (BRZ)
