I accidentally purchased (who knows how) 911 rear discs (SEB-205195C) instead of the 914-6 discs (SEB-105184C) I typically use. I run late 914-4 front calipers on the rear with a bias valve. I assume there is no way these will fit... Correct?

911 SC rotor
Diameter: 290mm
Type: Internally vented
Brake Disc Thickness: 20mm

vs

914-6 rotor
Diameter: 286mm
Thickness: 10.5mm

You would need an M caliper or simular. What are yiu3running on the front?

911M 3" caliper in front. I decided it makes sense to just return the 911 rotors and rebuy the 914-6. Expensive (shipping) mistake on my part.

Hi Aaron, I thought I was the only one putting front calipers on the rear. I run SC calipers on the front and braking is very balanced. My rear rotors are 914 solids redrilled for five lug. Best, Mark

and the offset is different as well
