Does anybody have the following Porsche Factory specifications for:

944 Turbo Front Brake Caliper Outside Diameter?

924S wheel hub center diameters, Front and Rear?

Bolt Pattern is 5 x 130mm. - Correct

Hey Tim its definitely 5 X 130 bolt pattern. I have Turbo brakes and could measure but not quite sure what diameter your looking for. I run 16" wheels to clear minimum and don't you run 17" or 18"? My car is late and the rims are like a 42 mm and a 50 mm offset if any of that helps.

Tm the hub size required is 72mm for the 944S2,951,968. The minimum radius from the center of the hub to the o.d. of the stock S2 or 951 ( non S) brake caliper is 180mm. Greg F

Thanks guys.

I do currently run 17" wheels but, I am trying to find a company that can supply a 15" wheel that will fit over the front turbo brake calipers.

I measured the hubs front and rear and measured 2.82" (72mm) for both and took a very rough look at the caliper OD using a tape measure and it was around 7" so the 180mm (7.09") is perfect.

Here is all the info I have compiled:

Hub Diameter Front and Rear = 72mm
Front Brake Caliper Clearance = 180mm Radius
Bolt Hole Pattern = 5 x 130mm
Bolt Hole Size = 14mm
Lug Nut Seat Type = Ball 14mm Radius

Tim if you find anyone please share, I run 16 to clear. I had talked to Diamond Racing Wheels last year about making custom wheels for us and he couldn't build anything with that much offset.

The only company that can mnake these for you guys is Kodiak Racing wheels. They can build the 50+ MM offsets in 15". They are 3 piece wheels, so they are not super cheap. Greg
