I have a line on what is supposed to be 997 c2s front uprights which should allow for turbo calipers. The parts catalog shows that the uprights should be PN 997-341-157/8-25. The part number on the upright shows as a 997-341-657-05. When I look at other 987/997(non-c2s) uprights I see the same number cast in the part of 997-341-657-05. This part number does not show on any of the catalogs. It may be a casting part number and not an assembly part number. My question is short of measuring the caliper mounting hole distance, how would I identify 997 upright as for the C2s versus a standard 997 carrera upright? I simply want front upright that will allow for turbo 6 piston brakes without an adapter. Any help would be appreciated.

 

I have turbo calipers on my C2S. They mount right up. If I remember correctly, you need to bend the front hard brake lines and perhaps cut a small notch in the rear dust shield with tin snips. The calipers themselves bolt on fine.

Use turbo caliper bolts though, they're longer.

 

So you have pictures of the upright and mounted caliper.

 

No direct picture but try these, all from my C2S with turbo calipers
