67/68 vented rear brake rotors

[gled49]

Can someone post inside and outside pictures of new Porsche rear vented brake rotors, My dealer says they are available, but I need to see what they look like before I take the plunge. Gordon

hmmm heres on from the outside....have no inside one...but i think what you need are some measurements.

Moito, do you have a shot of the rotor from the rear so I can see the venting slots. Thanks again Gordon

Hello

Use Porsche 944 rear brake rotor (cheaper). They only should be reduced in diameter (3mm). An other drill for little the fixing bolt. And that's all.

See on my 67:

Hi Gordon
I've just dealt with exactly this issue on my car (67S).
This is my thread on the subject (incluing measurements):

The part you need is 90135204115 (not 90135204114 which is the vented disc from 69-83)

Briefly:
SWB vented rear disc dimensions:
dia: 285mm
width of disc: 20 mm
inner disc face to top of bell house: 70mm

whereas
later vented type 69 onwards
dia:290mm
height from inside face to bellhousing: 85mm
width of disc: 20mm
best
Will

I still need picture of Porsche new replacement, so I can see the end of the rotor with the vents. This is not a project that can use anything else. Gled

So are you saying that a non S car could have had vented rear discs? Also, are there any vented discs for the front brakes that are not S sizes?

the L and sportos had rear vented rotors, I believe.

I just bought a pair from Stoddard at a reasonable price.
