I’m looking to upgrade my rear brakes with the JCW kit from WMW:

Question: Do I need to get JCW rear brake pads, or will my S pads fit?



My brake path for this spring is to get EBC redstuff pad set, use my stock S front brakes, and get the JCW rotors and brackets for the rear.

 

outmotoring.com says it's the same rear pads as an S. Just the rotor and caliper carrier are different.

"Factory genuine MINI rear brake pads complete and ready to install. Be sure to check the thickness of the rotor to make sure it is in spec and as needed purchase new rotors as well. This kit contains both the rear right and rear left brake pads. Please note JCW model REAR pads are the same as the Cooper and Cooper S for the Gen2. These pads fit all of the models listed below- as well as the JCW model."

 

Thanks.

I know the calipers are interchangeable, only difference being the color. However, RealOEM calls out different part numbers for brake pads between S and JCW sport brakes:

Wasn’t sure if the pads were interchangeable or not.

 

Our kit there just has the brackets to move the calipers out like the JCW. You will use your existing S calipers.
The Standard S and JCW rear brakes use the same pad so it doesn't matter

Here are the reds just select rear

Thanks for confirming. I’ll probably order the whole shebang from you in the coming month or so, for installation in the spring.

 

Am I crazy for wanting to use the rear JCW kit with my stock front S brakes?

 

I wouldn't say crazy but it may not be as much of an upgrade as you think. The actual surface area making contact hasn't changed because the pad and caliper are the same. Plus most of the braking is done by the front anyway.

 

Thanks for the response. I've been thinking about it more last night, and I might just pass on the "upgrade" to save the cash for other mods. Throw in a good set of pads and call it a day.

 

Just wait for a JCW front brake kit to pop up used. That's what I did, so now I have the 4 pot JCW fronts with stock Cooper S rears. I'll do the rear upgrade when I need to replace the rear discs just to fill out the rear wheels more, but that's just me.

 

I was hoping at some point to do a Wilwood front upgrade

However, I am in need of a brake replacement now and I don't have the resources for the front upgrade at the moment. So, I'll do the daily driver upgrade now, and the performance upgrade laters.

 

No I think it fills out the wheel much better.

And it actually fits and works right unlike the aftermarket kits the don't fit right or don't work right with the ebrake.

 

I just wish those brackets didn't cost SOOO much

 

I agree. My feeling is in the future they will discontinue them and make them only avail with the calipers. So right now they feel expensive, but if we have to get calipers too they will get crazy.
