Hello

I got a set of front and rear Boxster calipers to upgrade onto my 914.

Was told by the seller they are the non S versions.

Having issues with finding the correct front pads. The pads for the base Boxster dont fit correctly.

Spent a lot of time cleaning & refinishing these.

Wondering if I actually received S calipers. Is there a way to confirm what calipers I have?

Thanks

David

start with posting photos and part numbers

are they already installed on car?

pulled this info from a thread on the bird, in summary, S rotors are larger diameter and thicker. The S pad is larger. The caliper should be slightly wider to accommodate a 4mm thicker rotor.

Non'S':
F Disc 298mm, Pistons in Calipers 2x40,2x36 mm , pad area 216 cm^2
R Disc 292mm, Pistons in Calipers 2x30,2x28 mm , pad area 196 cm^2

"S":
F Disc 319mm, Pistons in Calipers 2x40,2x36 mm, pad area 254 cm^2
R Disc 299mm, Pistons in Calipers 2x30,2x28 mm, pad area 196 cm^2
