Default 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.
