R53 to R56 JCW Brake Conversion
#28
I know r104 and r90 along with challenge fits. My pace spoke does not.

Just did this on my 04 the other other day. Sadly they were from a wrecker and when they shipped them they did not wrap the calipers. Needless to say they were chipped to hell and back.
I had to refinish them. No luck finding a JCW template to put the logo back on. Looks like I will have to get creative.

Yes everything bolts up just fine. I was able to locate them using a junk yard parts finder. www.car-part.com is great to use. Just make sure you ask for images of the parts or a better descriptions just in case they catalog the items wrong.
In fact I just picked up a JCW airbox for 90 bucks shipped to my door from a yard in Florida.

Question, curious if folks are still able to monitor this thread after 10+ years! :-)
I have R52 S, about to do the R56 BBK install having gotten the calipers from 2nd hand.
I want and have already bought 316mm rotors for the front, 280mm for the rear.
A friend of mine is telling me that if I'm going to do the 316mm, I'll need mounting bracket extensions. He points out that the Brembo big brake kit includes them (which they do). But no matter what searches I do, I can't seem to find any indication that I need them.
So question is: do I need to do anything different for the R56 BBK kit if I'm using 316mm rotors on the R52?
Thanks!

I am collecting parts for this upgrade. Everything I've read says the R56S calipers use 294mm rotors. Can you confirm you're using the R56S calipers? Thanks

R56 S caliper with 294mm rotor
________________
Some confusion often comes up due to the various brake systems from the first two generations, especially when referring to the “poor man’s JCW upgrade” for a 1st gen.
The first gen came with 276mm front rotors and the upgrade available was the JCW kit with bigger front calipers, bigger upgraded front pads, 294mm front rotors, and upgraded pads only on the rear. The regular 2nd gen came with calipers the same size as the first gen JCW’s, but only with 280mm front rotors. The S came with the same calipers, but with different carriers/brackets to fit the 294mm rotors.
This is where the main issue lies with many of the brake upgrade threads. People often refer R56 brakes when they really mean R56 S (not you ). With R56 S calipers you should be using 294mm rotors. Unfortunately, some people end up with regular 280mm R56 brakes because of the leaving off the “S” part, and getting a separate set of carriers to make them work with 294’s can be almost expensive as getting “S” calipers in the first place.
This thread is referring to the 2nd gen BBK upgrade which are 4 piston Brembos and use the 316mm rotors.
There used to be a really thorough thread here on NAM, along with the same info on a separate website page where a member posted all of this info in detail and lot more on the various stages and options for upgrading MINI brakes, but unfortunately it’s gone now.

+1 the jcw four pot is a huge upgrade, if you are a gen 1 MINI period correct person the single pot works but you will not feel the big difference like jumping to the four pistons. https://www.northamericanmotoring.co...-calipers.html

Yes or i think you can also notch the round post but it might not hold tight.

Yeah, I went ahead and notched it, but then the cable geometry is such that it bends towards the shock strut, brake line, end links .... not exactly a good solution.
So I said "forget this ..." and went ahead and bought the R56 cables. I've done everything else as I should, so why should I take shortcuts on this one too ... 🤔
Fits just right, bends just right. (... that's what she said. 🤣
