Is anyone running Brembo F40 calipers?

Thanks,

No but I have a set to sell for $600. They bolt to 944 Turbo S Spindles.

And they look just like 928 S4 calipers.

Anderson and Fan both are using the F40-50 calipers on their 928s.

The clips that retain the pads are a little different, the offsets are a little different.

What rotor combination would you use with these to get the correct offsets?

hp18racer

993 Twin Turbo Rotor, 13" diameter. The car I took them off of used a longer bolt than stock to mount the caliper to the spindle and a stack of washers to get the offset right.

I have them on the back of my GT1 SP car

I would think it depends on the car the 928s use the 964Turbo offset rotors. (if the offset is the same as the bigreds). radially, when you use the larger diameter rotor you use the "washers" as spacers. Offset is different from how I understand it It depends on the spindle mounts and rotor config. usually, custom hats with replaceable rotors are required to get the 14" diameters that the F50 calipers deserve. Interesting enough, the calipers are near the same size at the S4's using near the same size pad too. The big reds use the big pad and are configured for the 322mm rotors.

Mark is right, my statement was incorrect. The rotors are picked to match the offset, the washers move the caliper out to match the rotor diameter. My example is for the M030 spindles on a 944.

Aren't the 4 piston F40 calipers the same as GTS-Big Red?

I know the F50 caliper is bigger & lighter, but uses a smaller pad like the 928S4?

mark kibort

The GTS calipers are the largest of the bunch, much larger than the F50 calipers. The pad difference is mainly in the inner diameter area.

I wonder why Michael is asking as he's obviously in the PFC camp?
Be interesting to hear what is available from PFC for people who want to move away from old tech Big Reds?

michael_mbsbrakes

The reason for my question, I have in stock some PFC 97 compound pads for that application. I kinda thought there were more Porsches out there running them.

Is that the 7780 pad shape? I have those on the front of my Boxster, and use PFC97's on it when I track it, which doesn't happen much with a race car in the garage. Now it's just a street car with too much brakes.
