15" wheels with 11.75" Wilwood BBK
Got 'em on tonight. Team Dynamics Pro Race 1 in 15x7, 40mm offset:


I forgot to ask the shop that mounted my snow tires to not put weights on the inside of the rim right up against the spokes, so that's exactly what they did on just the two front wheels. *sigh* Clearance is tight but it looks ok, and I drove the car a bit tonight (for the first time in a couple of weeks! Woo hoo!) and didn't have any problems. I'll post another shot of the clearance between the weights and the caliper when I get a chance.
So, there you have it: proof that these wheels fit with the 11.75" Wilwood BBK!

I like that second shot, saved it to my photobucket site.
I still get some calls of confusion on these kits. I personally don't think Wilwood has marketed them correctly. The 11.75 is for 15" wheel use. They refer to it as the "race kit" and that's a bit misleading.
A TCE Plus 1 kit: 11.75 can be had in many configurations for smaller 15" wheels.
A TCE Plus 2 kit: 12.2 can also be had in many configurations and fits 16" wheels.
The options for both these kits are almost completely interchangeable. The only limitation is RED finish on a stainless steel piston shod caliper. That's on the booted version only.
So....I'm pleased to help you get a smaller kit in red for your street car and with drilled/slotted/plated rotors just as I can produce it in black with or without booted pistons on a GT rotor in the larger diameter. It's really all in what parts are put into the box.

The Pro Race 1. They're still being made near as I can tell; they appear to be a current product. The se guys have full-scale templates you can print out to check clearance. I did that with the Pro Race 1, but not the 1.2.

That's probably the only part of the wheel I really don't like. I think the shop that mounted 'em scratched a couple of the spokes on one wheel (*grumble*) because of that. Hopefully I never have any wheel-to-wheel contact.
I'm seriously considering the Wilwood 15" kit.
1. Has anyone used the Konig Rewinds with the kit? Will it work? If so, does it require spacers?
2. My street wheels are the factory 16s. Any issues with that wheel?

Your 16s will likely not clear this despite the fact that the 11.75 rotor fits within a 15" wheel. It's not the diameter that's your issue; it's the caliper body overhang.
In any case, do check your wheels before you move on.

The factory X-lites would fit over the brakes, but on my car the clearance with the face of the caliper and back of the spoke was so close that I occasionally had rubbing. I got a 3mm spacer and all is fine.
Thank you all for your input. I would especially like to thank Todd from TCE with whom I just spoke.
From my measurements, the Konig Rewinds will require slightly less than 5mm of spacing to clear the side of the caliper just as blalor suggested. I haven't measured my factory 16s since they are on the car.
I also have a set of Kosei K1s. I measured them too and they should clear without spacers - as was previously stated in this discussion.
I learned from Todd that the Wilwood diagram includes some airspace. The true minimum dimensions to clear the calipers are 6.57 inches from the center of the wheel out and .95 inches from the spoke to the hub face.
My measurement on the Rewinds (using a metal ruler) at the closest point of contact on the spoke was ~ 13/16". . . less than the .95" required.
For anyone else considering this kit, Hawk is releasing pads for the Wilwood DynaPro caliper any day now. Pricing for the race pads is $100 to $125 less compared to the same compounds for stock calipers. If you track your car a lot, this kit should pay for itself in a couple of seasons.

FWIW, Hawk already has a pad that fits. They and most others either don't know or were not catering yet to the caliper market.
The DP caliper can be fit with the HB100 pad. However...it needs to be the .625 thick pad and not the .490. They had limited compounds for this some years ago. Also, the older form of this plate does not accomodate the current quick release clip in the CENTER, but has the holes in the end. A few minutes with a grinder and you'd have what you need.
The real kicker is the .625 so please beware if you call around for some, you don't want the thin ones. Or of course just wait and see what they offer new.

I also see some vendors listing HB237 to fit. I'd not got that route. While it can be had at .625 and modified in the middle there are no pin holes in the ends and the pads will slip through the body.

I just got my black Team Dynamics Pro Race 1 15x7 et+35 and did a quick test fit. I have all kinds of clearance. Now to get my 225/45/15 RA1s mounted and see if I have any rubbing.
For the record (those who require smaller dia for the use of 15s;
TCE can supply you both the "race" kit as well as the dust booted caliper and or the SRP drillled/slotted rotor for this size wheel as well. You are not limited to only the more track duty parts. I'm happy to meet your needs with ease.

I broke down and ordered the 11.75" kit from Todd at TCE, and it is a first rate kit. TCE was a pleasure to work with - extremely responsive to email and voicemail, knowledgable, and priced fairly. There's no need to look any further than TCE if you're interested a Wilwood kit.
Here's my experience with wheel fitment:
One thing to note on this kit: the slotted rotors are really noisy for the first several stops. The noise subsided after the pads were bedded. Be prepared. When you make your first few stops, you may hear some noise that will have you doubting your mechanical skills. That was my experience with the BP-10 pads.
I'm off to VIR in a few weeks. That will be a true test!
Here's my experience with wheel fitment:
- Factory 16" from 2006 MCS will fit without spacers - just barely
- Kosei K1 15x7 will fit without spacers - just barely
- Konig Rewind 15x7 will NOT fit without spacers

Thanks for that feedback, abarks (if that is your real name...
). Which 16" wheels are you using?
I'm now tempted to go back to Konig Rewinds for street use. I'm pretty much opposed to using spacers on the track, but I'd be ok with it on the street. I have those Pro Race 1 wheels on, now, but I kind of miss my Rewinds...
How will you be using each set of wheels?

Sorry if it's not quite on topic of the thread, but since I have exact same Willwood setup on my car but never tried it with 15 inches wheels (have been running on 16 inchers for trackday) What tyre sizes are you guys using for the 15" wheels? 205/50?
Right now I'm using snow tires that are (I think) 195/something/15. I intend to run 225/50/15 for the track (R-compounds, eventually) and hopefully the same for the street. That size worked well with my Konig Rewinds and stock brakes, but the selection is pretty limited. I'm *such* a slave to fashion, though, that it's worth it.
Please remember also that if you choose these kits you are supplied in the bracket kits a spacer that allows for fit of either the 11.75 or the 12.2" rotor.
While I discourage repeated exchange of the rotor onto the hat, you could do either that or have a second set of hats/rotors for moving between both 15" and larger wheels to accommodate the two different rotor diameters. Or for example you could run an "el cheapo" 11.75 straight vane rotor on your snow tires for Winter and save the 12.2 GT rotors for track day or 12.2 SRP drilled one for looks on your 17" Summer wheels.
