Looks like there's an "offset" issue with the passenger side rotor. The issue can be caused by a missing part or mismatching rotor hat to the driver side or somehow the wheel bearing goes deeper onto the spindle more on one side than the other side. The latter is the least plausible of the three but not impossible. Any one of the above will cause the rotor to be not offset correctly relative to centering the rotor to the caliper and the ball joint. The rotor looks like an aftermarket two-piece rotor with aluminum hat. The rotor friction ring may be of Coleman brand. With what little I can of the caliper it does look like a 993 Carrera(not turbo) caliper by the radial-mounting pads.

If I were you, I'd measure the driver side rotor hat and measure how the rotor is center to the caliper on the driver side and compare to the passenger side. A caliper adapter bracket is necessary for this brake conversion so measure the bracket to see if it matches the other side just to thorough(the bracket is responsible of offset of the caliper to the rotor, but not for the rotor to the ball joint). If it happen to be missing item #24 in the image then it will change the offset in an unfavorable way and more disturbingly render the inner(bigger) bearing to be not so effective, which I guess that's probably why the factory engineers designed this arrangement with a smaller outter bearing as a back up plan.

Good luck.

Bummer.

I lost track in all the car searching threads the particulars about this car. Powerplant?

What does it have for rear brakes if the fronts have been "improved" to 993 brakes?

Can't explain what is going on but I was one of those over the years who "upgraded" my SC brakes to 964 calipers and dealt with the annoying rotor size vs caliper size mismatching. While they were reliable and never faded, looking back, I wish I just got more air into the brakes and ran the slightly thicker 3.2 Carrera brakes instead.

At least you found this out now vs at the track.

More pics of the caliper, mounting bracket, back of rotor, and a receipt for some Coleman rotors from my Big Ole Book O' Receipts.

Shop does have the inner batting and a spacer, but didn't get a chance to pick them up, as I took the 997 to Dominion once the SC was a loss.

Its a 3.0 converted to 3.2 short stroke with PMO carbs - pulls nicely from about 4k...in the neighborhood, at least...

Yeah, I ordered all new front bearings, pads and rotors once I found the cause of the scoring and knew I wouldn't have it ready for Dominion - got ahead of myself with the rotors, though - ordered originals for the SC... Looks like I'll be checking out Coleman.

From the 2nd set of pictures it looks like the you have the right adapter. So my guess it's just missing the aftermarket spacer. It's used to offset the rotor for the very reason you are looking at.

From the other diagram #24 is visible in the 2nd set of photos. I think Renn Sport sells these kids and has a writ up on hoe to install/

Looks like that's exactly what it is. Driver's side doesn't look much better. Odd that just the passenger side inner pad burned off, though. *Just* enough clearance on driver's side, I guess.

Ouch! Tell me these Coleman's last forever with a proper spacer...

I think I'll be looking for a non-custom rotor solution.

Ha! Rotors are consumables. But hopefully with this setup they will last longer then rotors in a stock setup.

You gotta pay...

Not sure if these are factory 930 spec, but if so, the Colemans *are* the low-cost replacements...
