It wouldn't match. 328x28 Stoptech and 328x28 Brembo have much wider rotors with about 8 mm wider annulus, and bigger brake pads. This means better thermal capacity, better heat dissipation and as a result lower temperatures and longer wear.

Hmmmm - The piston size I found for the JCW sport brakes (the Brembo style brakes) is 34 mm, but I don’t remember the source. Do you have a source for the size you quote?

I do know, however, that there is a MINI factor recoding of the ABS system for the installation of the JCW sport brakes in place of the S brakes and that it made a significant difference in how the EDLC system worked with the Wilwoods. The Wilwoods have a piston size that is just slightly larger than what I found for the JCW sport brakes (34mm)and the recoding match pretty well with them. Without the recoding I was burning out brake pads and, literally, dragging the inside tire around some of the turns on the track.

Well, crap, that just ruins my whole theory as to why MINI recodes the ABS module for the JCW sport brakes.

BTW - Interesting solution to the MINI brake heat issue.

Good info!
Thank you.

Which model BBK's are we talking about below... and what are the best 'street' prices of those kits?
Is there any info on actual brake pad AREA given by the mfgs?
As far as the diameter, which is very similar for the three mentioned, what is the actual swept area of the pad/rotor?

Elephant in the room.... Can the BMW/MINI ABS be coded for ANY bias...or only set to pre-determined parameters?... and Most importantly, will that function really well, overall, as package with the car/wheels etc? The majority of these BBK's are installed on cars that are street driven as well.... is there a significant consideration to overall brake system balance/proportion and function of the ABS system controlling them by the MFG's of the kits as part of a systematic-approach to the end result... or is it left to the installer/owner to sus that out??

Do these, IMO, crazy-expensive BBK's provide re-coding instructions with the car-specific kits they are selling??

Many mfgs offer total "cubic" inches of material, few offer square inch data. And most pad plate dimensions are for application purposes not for trying to calculate the square inch info.

Pad "swept area" (the amount of rotor, sq" covered by said pad in one revolution) can be a ballpark start to function but does not tell the whole story. A larger pad with more swept area can generate less torque.

To that point; a larger pad does not create more toque or "power" compared to the smaller one assuming the same piston area is in use.

At this point here...in regards from torque....more area further from the center.... that is where the torque is generated.... is that correct??

Good call. Sorta....
You're speaking of what's often called the Effective Radius or ER. The ER is the 'average' pressure point on the pad relative to the pistons behind it. On a 2.5" circle it's obviously in the middle. On say a DP6 which has narrower (skinnier) pads the pistons are smaller and thus that line of average is higher. So yes then the leverage point is higher even if the total sq" of pad were the same.

Sorry, but I am still going to push the TCE Plus 3a kit. It is 13" (330 mm) rotor kit and it, too, has a crazy big pad:
https://www.wilwood.com/Images/Brake...Large/7420.jpg

Although it is narrower (0.81" thick) than the brembo or stop tech, it has a lot of mass to absorb heat and it will be more wheel friendly.

As for the MINI abs, I am not aware of anyone doing coding on these things other than the factory coding. Those would be for the Stock S brakes, the JCW sport brakes and the GP II brakes. Maybe some one else has better info on aftermarket ABS stuff for these cars.

I'll second the ABS thing. I'm no puter wiz but been doing kits since 2003. Both Wilwood and I began a parallel path of products that work well for a number of needs. None of them since day one have required any such tuning.

Todd,
At less than $2000 for the front and rear 13" kit... it seems like a lot of bang for the buck with the Willwood.

Can you also provide, for the upcharge, the custom colored calipers from Wilwood.. and if so, what is the upcharge and lead time on something like this for the F&R?

I believe their kits (and mine) remain the best value out there and have been for quite some time. I'm aware of the others and can't say much bad about any of them but at the end of the day it's hard to beat the prices they offer and the more extreme deals I put together.

The 'retail' on a pair of calipers form the Wilwood Color Wheel run....$499 pair. I'm under that with an order by a modest margin but can't publish a price. Getting the rears done is a bit of a bend over....

Let's say that the $2000 price point will run you about $2800 and leave it at that.

Thanks!

These would look great peaking out from behind a set of Challenge wheels on a BRG R53... EH??

thanks to you and everyone else who jumped on this one! So update. I bought the dynapro 6's... currently saving up for the wilwood rears... because vanity. But life setbacks are definitely going to prevent me from racing this season (or at least most of it). When I get them in and installed I'll post the nudes for you guys! Suspension is just Koni actives with H&R springs until I decide on coilovers.
thanks again guys!

Do you carry the rear bbk for the r53?

I've got the 12.88 wilwood dynapro 6s in black... I like it simple. Now I've got to decide on a wheel to put over these puppies in a17in. Not going to make it this season. Debating on sending Jan my motor or just the head and doing the block myself. But I'm going all the way on this. So it's going to be awhile.

Did Todd ever get back to you about the Wilwood rear brakes? He does carry them.

Another option is to get the Gen II JCW rear rotor and brake caliper bracket. These have a larger rotor than what you have now and you can reuse your caliper.
