Oh Jesus Christ, there is so much room in my Works for a BBK (Work Emotion CR Kais 17 x 8 ET 25) its unbelievable.
Obviously the Street is no problem, the Sport kit still has probably 20-25mm to the inside of the spokes, so it's apparent a Race kit would fit with ease.
I think I could have Lee build me a 330 x 32 mm custom kit with 6 piston calipers and still have no problem fitting them underneath those wheels. Although that would be completely unnecessary.
I think I'll save my money up for the Sport kit, so the brakes don't look so cute and tiny behind the wheels like they do now.

OKay then. So I received an Autocad file of the drawing for the 1.3 and I was quite excited to open it up and see what was changed from the previous versions.
The Pro Race 1.0 was a true race wheel. It was very light and was designed for big brakes. Indeed, the small barrel was quite large which made installing tires perhaps a bit more difficult.
So, here's the draft of the 1.3
I have highlighted the recess that seems to be made more for ease of installing tires, than to accomodate big calipers. Look at the circled portion. This is where it will interfere. My first tests show that the tips of the caliper still interfere radially by 1.5mm
I will later surimpose all three versions so that everyone can see the evolution of that wheel.
I drove to Mosport yesterday (300 mile drive each way) and met with Lance and Allan. Allan had a mint 1985 MK Motorsport 325 with M52 transplant and Sport kit. Lance Webb is a rally guy whom I crossed at Targa Newfoundland and just bought a 1988 racecar from Jason Legger to do some regional racing and 3 hours enduro events. We did some pad testing with Lance's car. He runs the Sport kit (300mm x 21mm blank discs) with Team Dynamics Pro Race 1.2without any spacer, on Hawk HT10s initially, then Wilwood's high friction endurance H compound. The pictures below show a direct fit - no spacer - no filling required. The tips of the calipers clear the barrel by about 2mm at the closest points.
BTW I highly recommend Wilwood's H pads on racecars. Much higher friction coefficient than HT10, wider temp range, friendly non-corrosive dust, very smooth on discs. They don't squeal, ever. They reach full friction very quick too.
One other recommendation, DO NOT use air ducts until you really feel some brake fade. Or you will keep the pads too cold, they won't be able to soften up and they will grind the discs faster than you wished. On such long track such as WGI and Mosport, no ducting needed for sure.

A shop that will also be selling Massive brake parts once our site is finally completed. :p
You should have your ARC-8 wheels tomorrow, and we all know those have great clearance :pimp:
