Hi guys,
Can someone tell me/confirm if these rear calipers are for a 914-6?
Thanks,
Bill.

Yes
4's are smaller with a "bump"

Please note that Mark is our local 914-6 caliper expert as he has his fair share of them

Thanks guys.
mepstein, where exactly would the bump be on a -4 rear caliper?
Thanks again for the help in confirming.
Bill.

Lol. No way, just 2% of what Eric Shay knows. Maybe less.
Probably less.

Don't mean to hijack a thread but I think the OP got his question answered. I have a similar question. Can anyone tell me what I have here? NOS units. I thought they were for a 914 (4?) but now Im thinking they are not.

Those are front calipers

Thanks. For a 4? 6?

Eric can tell just by looking. I can't. But if you measure the mounting holes, six (M) calipers would measure 3" from center to center. 4's will be less.

Thr fronts are -6. You can tell by the spacers. They are late model because they have the cup pistons.

I thought the spacers were only for vented discs. And the 914-6 didn't have vented discs from the factory. So they're not -6 calipers. They're 911 calipers.

Even if they were front 6 calipers, they aren't special. They're just 911 calipers, you can get them all day long relatively cheap and the spacers can be added if desired.

The rear 6 calipers are unique to the six and command a higher price because of rarity.

especially how to spell his last name

Actually they also are used on the Fararri 308 with spacers and twice the price.
I know where you can get a set that has already been assembled with new parts by PMB, if anyone is interested. PM mikey914

sent you a text about that

The 6 didn't have vented calipers from the factory ?

Apparently they did. Actually, now that I think about it. I don't think I've ever had a six with stock brakes in the shop. Still learning new things everyday, just like everyone else.

I thought stock 6's had solid rotors and GT's were vented.

Six's came with the same brakes as a 911T in front. . 3 inch bolt spacing calipers, vented rotors. .
Rear brakes were solid rotors and calipers had a smidgen bigger piston the the 4's.

Interesting. Thanks for info. I had purchased and installed some M calipers on the front of one of my 6 conversions. They are solid rotors. I wonder if they came from a 912.

I think Eric told me that the Ferrari unit had something different in the bleed valve. Something in its position. Eric said he could change it.

We went over it when I was looking for rears from 6s for my 74 -V8 car.

I'm pretty sure the difference is the bleeder screw. The Ferrari caliper is 'upside down' compared to a 914. On a 'normal' caliper you could just flip left and right. But since the eBrake is integrated, you can't do that. The eBrake arm and the bleeder need to both be in the right place. But as you said, I'm pretty sure Eric got himself set up to drill a new bleeder screw.
