Yes, the Boxster brake kit I listed above shows fitment for 912 (1965-69).

The only problem is that stock 65-68 front brake calipers have 3" spacing; 69 had 3.5" spacing...

I gave TRE a call to actually figure this out for anyone interested. We will be updating this info in the catalog.

That kit will work for the 65-68 912 only when you install the later model struts (911 S model struts) that have 3" inch caliper mounting spacing. This also means later control arms, torsion bar adjuster caps, ball joints, etc. will be needed as well.

Spacing info:

65-68 912 and 911 utilizes a strut that has 3" spacing.
69-74 912 they went with a different strut design, 2 available - 3" spacing and a 3.5" spacing which was standard for 911 S and option for the 911 T and E.

Before purchasing you need to measure the caliper spacing to confirm.

Haul,
Those kits will fit 69 LWB 912 cars with 3.5 S struts. You would have to convert to a LWB S, SC, or Carrera front suspension with a 3.5 bolt pattern for the 65-68 912's. I think TRE has made a adapter for the rear SWB brakes.
These E21 320i BMW ATE calipers (see below) can be used on your SWB car. They are like 911SC A calipers but with 3.0 bolt spacing. They are set up for solid rotors and use the same pads as my Brembo's and the SC A caliper. Much bigger pads. If you can find a set of Euro E21 323i calipers they will have spacers and are like the Brembo's I have but are made of cast iron instead of Aluminum. There are folks who took they're early Aluminum S calipers off and put SC/Carrera cast iron calipers on as they felt the Aluminum ones flexed too much. I'm curious enough to try the 323i calipers to see if that's the case compared to my Aluminum Brembo's as they are the same caliper in different metals. I found a set and will have them rebuilt. When apart I'll have my machinist quote me a price to reproduce the spacers. That way if someone buys a set of E21 320i solid rotor ATE calipers they could convert to vented rotors using the spacers.

M caliper with pads. 911SC, E21 320i solid/Euro 323i vented, and Alfa Brembo pad slipped in between M caliper pads. The bigger pad is inserted upside down and is resting on the caliper so it's a fair amount taller also.

I just bought a set of the rebuilt Brembo's off of an Alfa forum and should be shipping out today. Even came with a new set of pads and hard line adapter. Just to double check before I purchase rotors... any SC vented/drilled/slotted rotor will fit? Thanks

For the early 65-68 cars. You will need the complete front suspension from the 69 on cars. Also the wider space calipers are for the vented rotters. Where the very early cars had solid rotters. The advantage of the later suspension is the ball joint availability, cost and the 930 tie rods.

Any of the 'M" series brake pads will work for the "M" series brakes including the early 912s. They have for mine over the years. The thickness of the rotters from the early to the later cars is the difference from the early and later calipers

If you go for the bigger brakes like the S brakes. You will have too much braking in the front and could lock them up very easy for the lighter early 912.

Everything is 69' on the car, except for the engine which is a 68' and the trans which is a 71'. But as for the suspension, it's the stock 69' struts with the 3" spacing. That in mind, the Brembo's should bolt right up. But as for the rotors, will any year (78-83') SC brake rotor fit? As an fyi, the rear brakes will be updated in the spring, just before starting the driving season.

Brent,
Yes any SC rotor will fit. I bought Zimmerman rotors and had them cryoed. 12000 miles and they still look new with no visual wear. Use SC ATE rebuild kits and pads when they need to be serviced in the future.
You'll like them and they shouldn't give you the fizz.

I just installed my Brembo calipers today. There are two bleeder valves. Just curious which is recommended to remove and insert the banjo bolt?

Here's a pic of what I have so far. Should I place the banjo bolt in the low/central bleeder valve or in the top bleeder valve?

Most folks replaces the front suspension with a newer year to use newer brakes up to 1989. For a 912 they have gone to 911SC front suspension.
That is what I did, fairly easy if you have all the bits.

The hard line goes in here as I recall. No Banjo bolt. Just metric lines I bought from Napa and used a tubing bender.
I'll try and shoot a couple pictures tomorrow and post.
As I found these calipers to be WAY TOO HEAVY I just bought 10 (need 8) 10 mm Titanium alan head bolts to get another few ounces off each caliper. Kidding on the to heavy part. As I have one of only 2 sets of these Brembo's in the world with the 910 U shaped brake pad pins (Pete Stout being the other after he saw mine) I felt there were way to many like mine so the bolts where purchased. Of course I'll send a picture to Pete and he can do the same if he pleases.
I suspect you bought these from Rob. He's 10 minutes from my shop. I bought the Titanium bolts from him also. He and I built up about 5 sets of BMW 323iS calipers. 3.0 bolt space and they use the same pads as the Brembo's. The red caliper on page one of this thread is the 323iS caliper. Ours are gold zinc and like new. I'm going to use a pair of the 323iS calipers on a friends 69 912 2.7 POLO

Hi. I just wanted to report that I bought a set of the calipers from Rob. He is a super guy. I haven't put them on my car yet, so I'm closely following this thread.

Hope this helps.
I just noticed you have RSR bushings also. I have Clint's first SWB set for the front suspension.

I'm sure you are on this by now but, you want the bleeders at the top of the caliper as the air bubbles rise to the top. Duh! AIRC the stock ATE fronts are reversible, L to R depending how you mount the bleeders and individuals have found out it is impossible to bleed with the bleeders mounted at the bottom.

I have 3 sets of BMW 323iS calipers for vented rotors. One for my car, one for a friends 912 I'm puting a 2.7 POLO in, and a spare set I might part with if somebody wants them.

oh hi

Not to threadjack, but this is all very useful information - do the S calipers / 323 brembos bolt onto 912E's as well? I'll be refreshing by brakes soon, and this would be great to know "while I'm in there"....
