Nissan 370Z Forum - View Single Post - Brake Project and Interest: AP Racing CP9668/9660 Kit

DarkJak · 10-19-2022, 09:35 AM

Had a track day with passengers allowed where my wife kept swearing her M3 felt way more stable under braking. (She has CP9660 brakes on the front of her car fwiw) I've been writing it off to her MK60 ABS just being much more amazing than Nissan's, and I still believe it to be, but realized the car could probably benefit from more front bias, so that I'm not relying so much on ABS keeping the rear end behind me.

Will be switching to R16 fronts next year, whenever these pads finally wear through. I'm on 7 or 8 days, all at Blackhawk Farms and Road America, and they still have plenty of life left. Logging -1.15-1.2 G's for brake forces based off the Catalyst app, but getting about 0.05 more on lateral grip, so wondering if there's a bit more I could squeeze out with shifting bias.

EDIT:
I ran a price breakdown on my setup, because Essex finally released their kit at $5300, just to make sure this is still competitive. It really is.
The recent change in GBP vs USD has REALLY helped.

Price breakdown if self sourced:
10/19/22

Calipers: $2100
Brackets, lines, bolts and hats: $850
Rings: $900
Bobbins: $125
Total: $4075

My original goal of keeping this in line with Stoptech Trophy kits still stands, and should help justify the jump for someone needing more cooling.
