    I need to replace my right rear caliper soon, so i am looking at potential upgrade options. I have a late 2006 with the JCW brake package. Since I’m only replacing the rear brakes right now, would the R56 JCW rear calipers and rotors shift the brake bias to the rear too much? Am I better off just looking for regular R56 rear calipers? I put new MINI rear rotors and pads on about 3000 miles ago, and I might have a lead on some used R56 calipers and brackets, The JCW parts would have to be purchased new, unless somebody has a pair for sale.

    No they will not shift the bias that much.

    Thanks Dave.

    Is the R56 caliper actually different (aside from color and part #) than the JCW caliper? I know the rotor is larger, and I think the bracket is different, but I have not seen anything in person.

    That caliber is the same if I recal but the bracket is a little larger.

    Thanks for the info Dave. My lead on the low mileage R56 calipers was a bust. But it sounds like I can get the same setup and save some money by using regular calipers with using the JCW brackets with larger rotors.

    If you are still looking for the rear calipers, I can help. I got an R53 w/ the 2nd Gen JCW brake upgrade installed in for parts today. The JCW rear calipers do have a larger carrier like Dave mentioned, and they are nice and red.

    I am interested. My brother had a massive heart attack several weeks ago so all projects were tabled. I can’t seem to find the PM feature while using my phone. Please PM me a price shipped to 80911. Depending on the price, I may also be interested in a trailing arm upgrade as well.

    Thanks!

    I forgot this site now uses a conversation feature, so you now have a new message.

    From what I have heard rear calipers are really not worth the upgrade. I thought about it when I went BBK (poor man's JCW) but most were saying to spend the money elsewhere.

    rear upgrade: brass/stainless guide pin conversion, stainless steel hose, good pads and new rotors. Paint caliper red for extra performance. Done

    I did this exact same thing on my first R53... they held up beautifully w/ the 4-pot Wilwoods up front. I ran several track weekends through green, blue and early yellow rungroups and racing slick tires. I had to upgrade to the highest-temp brake fluid I could find, but once I did that, they were bulletproof (and I was probably cooking the fluid in the fronts anyway). I got the 4-pot calipers cheap from a serious track junkie (red run group / instructor) who was upgrading to the Outlaw calipers up front. I got a rebuild kit for the Willwoods and applied a quick coat of flat black BBQ grill (high temp) paint and they were perfect.

    I did the Wilwood upgrade for my new R53, front and back, but did the rears more for aesthetics than anything... that and it was a complete package that took care of all of my wants in one pass.
