I have the same setup as Andy but I installed the early 911 e-brakes on the rear.
It wasn't too bad had to measure alot to get things just right with the lever mounts.
I also had to make a small cable to attach to the 914 e brake cable.
I took a look at my caliper pistons like Aaron brought up . The rear calipers bolt right up ( small piston to the top ) as for the fronts they need to be flipped ( right now larger piston is on top ) .

So here I go digging up an old thread, and digging into minutia.

I know that the calipers that start with 996 are newer than 986, but does anyone have an idea on the next three numbers?

Rich said to stay away from the .352. calipers but I can't for the life of me see a difference when I have them in my hand. I'm on the hunt for:

986/996.351.421
986/996.351.422
986/996.351.424
986/996.351.425

Everywhere I turn, I'm finding sets that have 1 or 2 .352. calipers in the mix. Can they really be that different?

I just checked my calipers and this is what I have for #'s.
Fronts are : 986 351 421 & 986 351 422
Rears are : 996 352 421 & 996 352 442

Why stay away from the .352 # ?

I have the standard Boxster calipers but there's also a Boxster S calipers which is different from what I hear.

Hmmm...

I've got another set on the way. So I'll have to see what the part numbers are when they arrive. I KNOW the last set was wrong. (They shipped 3 rears and 1 front.)

Thanks gang.

Don't try to run one of the collapsible spares with the Boxster calipers. The offset is wrong and the caliper locks against the wheel (BTDT)

I bought a Boxster spare rim so I don't have to worry about it.

I got a full size 7" cookie cutter as a spare wheel, so no problems there.

Andy, can you pass on Rick Johnson's information, his adapters look so much "beefier" than the other adapters I've seen.

(IMG:style_emoticons/default/agree.gif) Better than what I've been trying to work out. If he's making sets, I'd be in for some.

What happens if you use the 996 part number rear calipers (still non S) ?
i.e. part numbers 996 352 421 & 996 352 422, (rather than 986-352-423-01 & 986-352-424-01 as stated below) ?

I see Luke asked this question way back then but I don't see an answer. ( I have some of these 996 part number rear calipers and need to know if I can use the adaptors and whether to use SC 20mm rotors or 24mm Carrera ones on the rear.
Regards
Andrew

Andy - did you flip the link lines and the bleeders on the front brakes so that the larger cylinder is at the bottom? Recall that on the Boxster the calipers are the other side of the strut (inboard).

I've seen some expensive 911 builds where people have forgotten (or were unaware) of this. Not sure it makes a huge difference to stopping power, probably just uneven pad wear....

Anyway,

- Tony

PS. Looking back through the thread, I see the issue has been brought up already; oops.

I just put this setup on my car yesterday:

- Carrera front rotors / Boxster front calipers
- SC vented rear rotors / Boxster rear calipers

The front calipers are swapped left to right and vv.

7X15 and 8X15 Fuchs easily fit.

Someone mentioned bolts not mounted in shear... all are mounted in shear, yes.

I set up the rear E-Brake with 69-73 type 911 shoes. Cables will run to the bottom, not through the trailing arm nor with a lever mechanism. I welded parking brake brackets in a new location. This alteration was easy.

Anyway, I highly recommend this setup.
