You'll have to wait a couple weeks unless you want a set for the 951 spindles.

I have another 1-off kit that I can build also.....Bigger Blacks would be an awesome short track autocross option.

To get everything ready, where did you get the 7/16" screws? They McMaster #91251A678 ?

I talked with Tim and he will post back if a 2.50" bolt will work as I tapped them as far as possible after pre-drilling to spec.

ACE Hardware has them as this is a common thread size. Get the black-phospho coated cap-heads and use Loc-tite. Very Happy

Ok, I've been to two Ace stores and neither had the bolts, I'll order some from McMaster Carr next week. Photos below show the updated adapters. I had to do some modification to make them work with the ABS sensor but that was easily done with a grinder.

Thanks for the pics. What is the depth of the arc from the bottom face of the adapter and it's base width?
I'll program in an arc on the next batch. Still can't get over the pad size on these. Shocked

I was at shop last night doing an M030 mock-up and have 2.5" bolts for it that I tried and they plunge the full depth without issue. The black-oxide bolts have never given me issues over the years installing directly into billet (But I do Loc-tite them). On yellow-zinc bolts I always use NAPA silver high temp anti-seize when installing in alloys with no issues.

Depth is 13.7 mm

my cut in no where near an arc, more vertical cuts. If you want a nice arc, start your cut at the inside edge of both bolt holes.

Thanks Tim, I updated the first post. I am working on the final adapter design to mount these to the 928S as it has to have Cayenne rotors as well for their hub/spindle offsets...

They clear the steering knuckle with the Cayenne 330mm rotors...
The trackers are using the inexpensive ATE 330 rotors...

Tim -
I just got my set of Wilwoods. Am I that drunk in the garage or did you also have a problem with the way the caliper was mounted to observe the rotational arrow, the bleeders were on the bottom?
Doesn't seem like a hard problem to fix, but just wanted to make sure I didn't get the british versions or something...

Some cars mount calipers leading the strut, others like our 944s mount them following the strut. The crossover tube and bleed screws can be swapped, setting the caliper up for the other style. I had to do this to mount BigReds (993 is leading strut) on my 944v8.

My beer fridge is in my garage, so I too often wonder about this  Shocked  Mine were set up backwards and I had to switch the bleeders and crossover pipe. While you are doing that, I would suggest that you replace the piston seals since you don't know when they were done last. They are $17/caliper, not $17/piston like the porsche parts. The bleeders are like $10 for a set of 4 from Summit. Not sure on the crossover pipe cost, I did not replace mine.

Spent the day at Taladega Grand Prix working on the brake system. In general I am very pleased with the Integra 6R setup/cayenne rotor setup. Braking was moderately better than the Turbo S setup that I was running. Again, the benefits that I am looking for are heat reduction, longevity of consumables (pads and rotors), and cost of consumables.

Tigpri is notoriously hard on brakes, lots of hard braking but not much straight running to cool them off. Coming off track rotor temps were 750/550 (front/rear) and front calipers were 300 (IR pyrometer). Need to pull the wheels and check my temperature indicating paint to see what max temps were.

Although I was able to get the balance where I wanted it using the DMC balance bar, the throw on the pedal is a bit long for my taste. I currently have 3/4 masters on both the front and rear (rear calipers are turbo/968 rears; previous setup with Turbo S fronts was 5/8 front 3/4 rear). If I race in three weeks I will stay with the current setup since it is tested, but at my first opportunity (DE), I will likely increase both masters to 11/13ths. This should fix the pedal throw but mean I have to push harder (manual brakes) to get the same pressure at the pistons.

Sounds right. Scotts 951 (factory vac booster and MC) runs these with early 951 brembos on the rear.

I programmed the ABS clearance on this last set.....

Thanks guys! I new it shouldn't be a problem, but was looking at it between sips thinking 'that's not right!'
Great to hear the feedback on how they are on the track. I'm really excited to get mine mounted up. What pads are you running? I'm sure I'm going to have balance issues also so that will be another challenge.
I have a strange 'problem' as I find myself with two sets of Wilwood calipers (maybe mount them on the rear?) Wink A rebuild also was in the cards for both of them and agree that starting fresh on brakes is a good thing! For others, the piston rebuild kit is Wilwood 130-5660 I haven't found the bleeders yet but will try to share.

Looking forward to trying them out soon, but first some chump racing!

All part nubers for the integra 6r's are at http://wilwood.com/Calipers/CaliperProd.aspx?itemno=120-5690-FS . Then just search the numbers. Summit has just about everything.

Don't put those wilwoods on the back, you will not be able to balance it front to back.

I have another 928 guy looking for a set of Integras. PM your info. I'll pass along.
he'll balance them with a set of Wilwood Dynapros 1.25" on the back.

Putting the extra set on the rear was just a joke. I agree it would be the wrong thing and be very hard to balance.

I've had good success with PFC in other calipers and will probably run them in these. I know I've seen a few sets come up lightly used. At this price, it's worth just playing around to see what you like the feel of! Something I didn't want to do with $350-400 sets of pads

xschop - if you have someone interested let me know what price they're thinking. I don't see any need to keep two around and don't think my other cars will migrate to these calipers.
