I'm looking at Todd's P1 Track Kit with the 12.19 rotors in front and the Wilwood Parking Brake Kit for the rear. I have two sets of OEM wheels (R121 Conical Spokes and R110 Pace Star), both of which seem a little too shallow for the calipers to clear. 5mm doens't seem like lot of difference, but I guess they only need to clear by a bit to work huh?

Even with careful measurements it feels like a leap of faith to just order and hope all will fit. I've got a buddy who owns a tire / brake shop who will do the install, so I've at least got some pro help there.

 

That is a great kit. Had that on my '07 S. A lot of stopping power.

Do I assume correctly that you intend to track your MINI? Then the added 5 mm of a set of spacers would be helpful for tire wear. The 48 mm offset that the stock MINI wheels have results in a fair amount of rollover of the front tires in corners. Less offset, which the spacers will provide, helps to improve that. Yes, they only need to clear a little bit. 5 mm is just over 3/16", you could that amount of cardboard and set it on the wheel hub and measure the clearance again. Also, if I remember right, the template that Wilwood gives is a little conservative as it doesn't have the rounded corners of the actual caliper, although that too is a leap of faith.

Good luck with it.

 

Duaflex,

I have the Wilwood 12.19 rotor and Pace Star wheel on my Clubman right now with the 5mm spacer and they clear fine. They are required since interference occurs at side of the spokes nearest the rim, there is plenty of space in the diameter. Rather interesting that my Enkei RS+M 16inch wheels clear with no spacers.

 

It's my daily driver, but Northwest MINI hooks customers up with a few track days each summer, so I'd like to get out there and drive it without cooking the stock brakes.

It sounds like 5mm should be enough extra for the R121's and definitely for the R110's.

Thanks for all the help!

 

I've got a beautiful set of black conical spokes that replaced my Pace Spokes when I bought my Clubman and I'd love to find a way to run the Wilwood BBK with them. Second choice would be to have my Pace Spokes painted black and run those.

Thanks for the info. I appreciate knowing the Pace Spokes will work with 5mm spacers.

Cheers.

 

The 12.19" Wilwood kit fits under my 16" Bridgespokes without any spacers. I've had them on all winter. Please excuse the dirt and salt.

Looks great!

Is this the race or street kit which retains the dust boots?

 

This is a real good representation of how the spoke clearance has such and effect on the brake kit. This is a 16" wheel and fits, yet larger 17" wheels don't; not because of the diameter but the wheel design.

 

Thanks I'm hoping my infinite streams will fit next week when I get new tires mounted on them. They fit the JCW brakes, so I'm hoping it'll fit these too.

It's the street kit.

Infinite Stream fits the Wilwood12.19 setup as well. Plenty of room to spare even!

TCE 13.1" Kit with FNSL4R Fit over XXR 527 et25 17". No spacers

 

Nice look. Those brakes fit well in those wheels. Also, that is a great track setup; especially useful for the amount of power your car has and top end it will produce.

 

Is there a list available that would show what 16" wheels would work with Wilwood 12" And 1" drop?

 

There's a list of wheels that will fit in the OP, and others that aren't accounted for throughout this thread (even one on this page). The drop won't make any difference.

Hey All, just wondering can 15" wheels fit onto the JCW R53/R56 MCS brake? Thinking about using 15" wheels.

 

Guys what brake kits will fit under Enkei RPF1 7*16 ET35 wheels without spacers?

 

I just put on the 16" Enkei RPF1 with the Wilwood 11.75. Purchased this week from Tirerack and I'm running 5mm spacers but I really think I could make it without the spacers but it would be VERY close. I'm also running Megans with this setup.

 

Thanks for sharing, although i think the 11.75 kit is not worth the money compared to the R56 S brakes i am running now, because it has thinner than stock rotors and almost the same diameter.

 

Gotta agree that the R56 brakes work better. I had a 04 MCS with R56 brakes and they were much better stopping wise than the Wilwoods I have now.

 

Sounds like you may need a different pad.

--Matt

 

First time I've ever heard someone state that. But we all interpret things differently.

 

I may be in the market for new pads if that's the case. I have heard nothing but good about the Wilwoods and was disappointed with my experience. Pad suggestions for daily driver?

 

Just a guess, you are wasting your time with the 11.75 kit. The disc is thinner than the OEM (20.6 vs 22mm), the "leverage" is virtually the same as there is only 2mm difference in the disc radius compared to the R56/JCW disc (294 R56/JCW vs 298mm disc diameter), and because of the design of the disc (larger than the OEM disc inner diameter of the contact surface), you have less surface per revolution of the disc too. (to be more precise, you have 12% less friction area per revolution of the disc with the Wilwood 11.75 compared to the R56 brakes) The only real advantage is the reduced unsprung mass, but nothing more.
The 11.75 is an upgrade for the standard 276mm discs, but not the 294mm

 

Here is at least one MINI that didn't find the 11.75 Wilwood kit a waste of time:

Trust me, that is not a slow time around that track and yes that is a street car.
I do know the owner of that MINI and have ridden in the car and can attest the the capabilities of the brakes. They are much better than the single piston R56 MINI brakes, which I have run.

There is more to a set of brakes than weight and diameter of the rotors. There is the ability to through repeated high speed braking applications without fading. Even with the same high end race pads both setups, the Wilwoods perform better, I've been there, done that.

I suspect Todd is right (what would he know??? ), putttn just needs a better pad and if he is going out on the track, a good brake flush.

 

Gotta love that run in a street car, and the view out the sunroof was just an extra delight.

I've had the Wilwood 12.2in with BP-10 pads on my Clubman for almost a year and they are far superior to the stock brakes. From what I calculated the 12.2in Wilwood pad area and piston area are only about the same or even less than stock, but they perform much better. I wore out the stock pads and rotors at 18k, and always had dust on the wheels. I have driven the Wilwoods the same for almost 8k miles now and can't detect rotor or pad wear, likewise the dust is hardly there. The brakes do not fade like the stock setup did and most importantly in a particular panic stop the grip was phenomenal - I'm sure it saved me an accident. The only difference I see between the 12.2in and the 11.75in is the extra leverage so if your not satisfied with the 11.75in I would simply try the more aggressive pad.

It's also not trivial that the unsprung weight savings is more than I got with lightweight wheels. Needless to say I'm never going back to stock.
