"can you name this calliper on this 964?"

You guys got all helpful and technical.

I was just going to name it Grippy.

tcsracing1

here are some more pictures to help solve the mystery

The part number on the rotor shows it being 964RS and 964 3.3L Turbo

The brake pad part number is slightly different however than what goes on a 964RS and 964 3.3L?
Not sure where that gets me.

Do people here typically keep the pad sensors?

I run sensors on street pads but not on track cars. I would assume they are 3.3T/RS calipers then.

This pic appears to show the extended base that was only used on the 964RS & 964 3.3t front calipers


Here is a 964RS & 964 3.3t front caliper, note the extended base mounts


These 2 are normal 993 front same caliper and pad as above but w/ flat base mounts, ignore the colors



Not to be confused w/ the 993RS, 993tt, 964 3.6t, , 'Big Red' front that also came in black on 928GTS, besides a chunkier side appearance the tip off to these is the squared off area at the top of the pad box

And they are brothers from another mother.

would the adapter bracket for a 964 3.6L T and the 993 Turbo be the same bracket to install the calipers on a 964 C4?

cobalt

The 964 T and 993T hats measure differently. The 993 hat is 5mm shorter than the 964 so you would need a different adapter depending on which rotor you choose.

Bill Verburg

an adaptor bracket has to accommodate 2 dimensions
axial o/s
radial o/s

so assuming that the axial o/s is for 964 rotors(not 993 rotors which are different) yes, the same adaptor is used for any of the 3 possible calipers
but
the adapter/caliper combination must have the appropriate rotor
Big Red(taller) & 964t/RS front caliper(extended mounting bases) will want a 32x322mm rotor this is the rotor used on 928GTS(not drilled) or drilled 964RS, 964 3.3t
993 caliper on 964 will want a 32x304mm rotor used on 928S4(not drilled)

Of course no caliper adapter is used w/ the steel 964RS/t wheel carriers w/ 964 rotors or w/ the aluminum 993 wheel carriers w/ 993 rotors
