can one of y'all identify this caliper?

[jmz]

Are these from a 993TT or 965 maybe? These are on a 914/6 GT Race Car I just bought. ...believe it or not it has 16" rims that just barely fit.

wrong picture, i meant to post one with a better visual on the tape measure. ...13" rotors.

[jmz]

and these are the rears. ...I think these are maybe 944 turbo or 928s brakes?

That's a 993tt 'Big Red' the rotor shoud be 322x32mm(oe size) to ~350x32mm

also used on 964 3.6T and 993RS &Cup , black version used on 928GTS

Hard to say they are older small size Brembo used on 964, 928, 944t, 968 etc

there are several version, all the rears have 28/30pistons and are sized for 299x24mm rotors, there is a 964 version that had 30/34mm pistons and was sized for a 299x28mm rotor, but these are very rare. There were also some front version w/ 36/40mm pistons and sized for 299x28mm rotors.

I have never worked on a 914 but on a 911 you would want the 30/34 964t version on a 309x28mm 930 rotor

all the rears except the above have pistons too small for best bias on a 911, the fronts are too large for decent bias, better to have too small rear than too big.

I have a set of 930 calipers on the way... kind of like the idea of 15" wheels for "the GT look"
