uhhhhh...... Please tell me what these are, I'll pee my pants if they are what I think they are.

They are 930 brakes. Were you hoping for 917?

[thomschoon]

930, the picture looks like the one posted at www.autozone.com where you can order them rebuilt and with the core charge they are still only around $145 each. Only problem is that I tried ordering them a few times and they were never able to get them it, but I havent lost hope.

Yep, 930 brakes. So what gives? Do you have a source for them? I'm still in need of a brake upgrade for my '72. I've been holding out to see what DinFtown comes up with for 15" fuchs...

Yep...they be 930 calipers...

Is it possible that they are knock-offs, made the "same way" but using some cheap ass metallurgy more common in lawn furniture?

Josh, have you absolutely, positively ruled out Carreras on the front? Have you tried it and found insufficient?

There has been the concept of using BMW's 320 4 piston calipers on the front due to the pad increase AND ability to mount them on 3" ears. Anyone know how thick of a rotor those calipers accept? 'Teener guys, anyone...anyone?

I haven't ruled out carrera calipers. There are two things I'm looking for in an upgrade:

1) Increased thermal capacity on the ROTOR
2) Stiffer caliper (the aluminum S calipers are spongy)

The carrera/boxster calipers take care of #2, but according to Bill V, don't offer much more thermal capacity. The 930 rotor is 32mm wide and seems to be the universal fix. The carrera rotor is 24mm. I believe my stock rotors are 20mm (mine are 18mm now -- time to be replaced).

I've never run out of brakes at the track. I'm just planning for future upgrades to the car as I don't want to go through this more than once. A hot 2.7 or a warmed over 3.6 is in the cards (still undecided if I want a high revving screamer or a torquey, bulletproof motor).

The conversion w/specs is covered very well on Pelicanparts.com under the teener tech article part.

Looks like we're in the same boat. Seems like unless you go "the beemer way" it's still necessary to get the 3.5" ears (which I don't have yet.) Compared to the cost of a 930 system, it seems like it's worth to give the Carrera setup a try. (I'd rather spend $350 than $3500)

david,
thanks for the direction to the 914 pp article. It's thorough but still doesn't answer the question of whether the caliper will accept the 24mm Carrera rotor. They only talk about the 911 rotor, meaning 20mm. Since I already have the 20mm, unless the 320 caliper accepts something thicker, for most of the 911 crowd it's not really an upgrade. You just gain clamping force, but not any more thermal capacity.

Does anyone know whether the 930 calipers accept a "standard" pad or are they Porsche specific like the M pads?

I guess I missed the rotor thickness question. I thought you were looking for the slightly larger pads from the BMW as a stop gap to the 3” ear issue. To my knowledge no stock ’65 to ’89 911 caliper fits the 930 rotors except the 930 calipers.

What other manufacture/application uses the “M” pads
