944 turbo front brakes - are 993 fronts the same?

[DavidL]

Do S and post (SE, 250 bhp, m030, call it what you will) cars have the stock 993 front caliper?
I know the 928 s4 are the same but are the 993?
I'm fairly sure they are and it opens up a larger pool of options especially as 993 owners upgrade to turbo brakes.
Thanks

I am pretty sure they are, but not 100%, they are not cast with the Porsche logo., but come with decals to save on cost, some will have been destined for other marques and their sticker will have been applied Ferrari etc.

I have 993 calipers on my car. The collars need machined down to fit and they are radial mount. So you can only fit them if you machine the collars down and you have M030 on your car with radial mount front brakes.

They can use standard 250 car discs and pads which is what I do.

928 are the same.

What do you call the collars?
We fitted a set with M030 hubs on a friend's '86 turbo and I can't remember any machining was needed.

I would expect that 993 brakes are not all the same,

My front calipers were off a 993 turbo. I am referring to collars as the part of the caliper where the retaining bolt goes through, at the mating end of the caliper and hub. This required some metal removing so they fitted onto the M030 hub.

IIRC - Ferrari 355 brakes are the same.

Although, they probably buy the Porsche ones to save money

993 turbo brakes are the big reds, same as the big blacks on 928 gts but a different colour. As far as I can surmise they seem to be the same thing. But they are different to the NA 993 brakes which may explain why they need a bit of fettling to fit. I'm going to compare my m030 brakes to a set of 993 ones in the next couple of days and see what's what.
Only problem is that I've got a new set of red rear calipers to go on so I need red ones for the front!

20.4692 is the brembo code for the front L I think on a 355 which seems also to be a stock 944 turbo code too. Interestingly used bits on ebay are much the same price. I can't decide if that's a cheap ferrari part or an expensive 944 one.

The mounting on of 993 turbo caliper and M030 hub should be the same. Any mod to the caliper will be due to the diameter of the disc being used i.e to ensure the pads are in the correct postion on the disc face.

Yeah that seems spot on seeing as a 993t uses 324mm disc and i am using 302mm discs, hence my machining brings the caliper back in line for 302mm discs.

You can fit the discs too, then you don't need to modify the calipers, (I think late 964 turbo discs) but you need 17" wheels.

I think the discs are quite expensive, can't really see the point in fitting the tt calipers and not the discs though. Unless the calipers were cheap.

 

[scam75]

£200 for the calipers in good nick. Wont be changing my 16" CS wheels anytime ever so did what was needed.

I think the 928 solid (vented) ones were expensive but the 964 turbo cross drilled were much closer to 944 ones in price. I need to look through my paperwork to be 100% they were 964 though.
My CS wheels are safely tucked away in the garage

Always thought holes cost you money....

I have 964 RS rears (crossdrilled)
