Price
$1,550
- Location Mentor, OH, 44060, USA
- Condition Used
Description:
Listed as used, but these a fully refurbed, as the pictures would suggest.
Facts:
- The 135i brackets were modded to align the caliper correctly for use on the R53-R56 Series cars (4-lug cars) with no mods needed to your spindles.
- The coating is a 2-part ceramic urethane (high heat) paint with painted-on logos (same chemistry) wet-over-wet for a chemical bond.
- The rear JCW units have a custom vanity plate recessed into the caliper and epoxied on.
- The steel brackets are sealed with epoxy primer and top-coated with a wrinkle coating
- Stainless screws swapped in for the weights
- Wheel template: http://bd8ba3c866c8cbc330ab-7b26c6f3...t_template.pdf
- Installation guide: http://bd8ba3c866c8cbc330ab-7b26c6f3...tallation1.pd
Notes / Recommendations:
- Ensure that your installer (if you're not a wrench) will install aftermarket parts.
- Dust shields may need trimmed or removed to fit the massive front binders.
- Accessory items such as lines, sensors, and fluids are not pictured or provided.
- Rotors are NOT included. The correct geometry for the matching rotors should replicate the following:
- Front = Centric P/N 12X.34160
- Rear = Centric P/N: 12X.34113
- Pads are NOT included. The correct pad shape for these calipers can be found using FMSI# :
- Front = FMSI D1371
- Rear = FMSI D1309

Just confirming I am seeing it properly, that unpainted steel bracket on one of the photos of a front caliper is what bolts to the knuckle? Would it fit an R53 with 17" wheels?
These use a 12" rotor. Unless I am not remembering correctly I believe my JCW R53 has 294 mm or 11.6 inch rotors. So a 0.2 inch rotor radius increase.
Wow, they look great.

Well said.
For the R53 guys here's some info on that: https://www.northamericanmotoring.co...ns-on-r53.html
To answer questions on the MC upgrade, it is indeed just that. An amenity (not a necessity). The piston area of the 6-pots are roughly the same as 1 or 4-pot units they are replacing, which is why the pedal feel has previously been confirmed as unchanged with the 6-pot caliper upgrade. (pi*r-squared)

135i and GP2 calipers are not the same! They can be used, but they should be used correctly.
