AP Racing CP9668/9660 Brake Kit Hardware

More info here: Brake Project and Interest: AP Racing CP9668/9660 Kit

Short of it is, after years of testing and changing up my brake setup on my 370Z for the track, I decided to make my dream set of brakes a reality.
AP Racing Pro 5000R CP9668 calipers with their 72 vane 372x34mm J hook rotors!

AP Racing CP9668 calipers allows for 25mm thick pads, is super rigid, and crazy light. The 9660 calipers are even lighter and slightly cheaper, with a bit better wheel clearance.
The 372x34mm 72 vane J hook discs from AP Racing are the best I could find that would comfortably fit under 18 inch wheels and be readily available. I've attached a pic to show the difference between AP Racing, OEM, Z1, and Wilwood.

I got final production units made in a batch of 3. One set is going on my car, and I have two left for sale.

The kit at $900 includes hats, brackets, 4 grade 12.9 caliper bolts, and SS brake lines. If you already have SS lines with M10x1 banjo bolt ends at the caliper side, I can exclude the lines for $850.

Pickup is available in Madison, WI, and have these also listed at 370zed.com, for anyone wanting to make payment through Shopify. I also take PayPal Goods and Services and Venmo.
Shipping isn't a problem either!

FAQ:
What do I need to complete this kit?
You need a pair of CP9668 calipers (L/R).
A pair of rotor rings: CP7177-350RC, (L/R).
Two sets of bobbin hardware to attach those rings to these hats: CP2494-1341K12.

Where can I buy the rest?
Calipers are significantly cheaper buying directly from a UK shop.
I got the calipers and bobbins from AP Motorsports, UK, and the rings from Flatirons tuning. Alternatively, Essex is a great vendor in the US, but price ends up significantly higher.

Can I buy the full kit from you instead?
Absolutely! I can work with those vendors to ship them directly to your address, and have this option on my site.

What pads should I use?
I can help you out on pad selection. All common track pads have been made in this shape, from my searches, and I can help recommend pad combos for you.
Staggered Gloc R12/R10 pads have continued to work great for me with these brakes.

Bump:
For anyone willing to use a 1mm shim (I used some large copper ones for a few tests before my final brackets came in), or run the caliper slightly off center, I have one pair of brackets available for $300 off.

Post-test bump:
I'm thrilled with testing at Blackhawk Farms this weekend.
Running a full weight, aero car at full pace for almost all of each 25 minute session, the brakes held up and didn't break a sweat.
Rotor temps were about 200F lower than my previous custom Wilwood rotor setup, and pad wear was negligible.
Pedal was much more consistent and firm, and bias felt spot on.
I am pretty confident anyone moving up to these will also be very happy with the jump up.

This is incredible. Well done, man.

DarkJak · 09-01-2021, 10:20 AM

Bump. I can provide recommendations on shops to buy from for the calipers and rings, or just handle all that for you, too.

Hmm, interesting. I might jump on a set. PM me the details about where to source the calipers, rings and bobbins with part numbers. Thanks.

PM'd.
Calipers I got from the UK. Ended up being about $2200-2300 for the pair after shipping, from APMotorsports. Same with the bobbins. Shipping took all of 2-3 days.

Rotors I got from Flatirons tuning, though I think they just dropshipped from Essex.

Best lap from my last day at Road America

I ran two days over a weekend, almost always with a passenger (even more weight!), and brakes were strong and consistent the whole time.
Pads still have well over half thickness left, with 3 days total on two really brake-abusive tracks. For comparison, my old Akebonos were going through pads to the backing plate before the end of their second track day!
Rotors looking healthy, no signs of failure anytime soon.

DarkJak · 11-01-2021, 06:09 PM

Bump, have 1 set left. Anything beyond this will require a longer wait time for manufacturing.

I was able to drop prices on my part of the kit because I found slightly cheaper shipping.
On the other hand, my pricing on the full kit with me sourcing calipers and rings didn't account for recent price increases on those parts and merchant fees so I had to adjust that up a bit. Still cheaper by a lot if you source yourself, since I have to double ship and go through two sets of credit card fees (mine plus AP Motorsport's).

1 set left!
I'll eventually get another batch made but not until next year due to a tight budget this month and next.
