4 piston rear brake calipers

[marksearls]

This is a cross post as I am looking for a set to replace my 2 piston rear calipers:

WTB 4 piston rear 964 calipers

Is this a direct bolt on and are there any other modifications that I need?

Thanks, Mark

While it is a direct bolt on you may want to either replace the brake proportion valve (Part 9643553-510) or gut it.
I swapped out the 2 pot rears for the 4 pot and since I dont track the car have yet to change out the valve.

You can also use the 944 turbo rear calipers, you just have to swap out thebleeder valves to the crossover pipe...simple enough

I am sure BillV will come along and give his position and I would definitely listen to what he says!

I did this on our '91 w/the proportion valve. Easy swap and much better for finding brake pads for the track.

Thanks for the heads up to change out the brake proportion valve as well. I guess I will add that to the list.
