    Default RALT RT-5 front discs

    Does anybody know what the front discs on a '84 ralt rt-5 are off of?
    Have been told they are off of stantard VW from that era but unable to locate
    The dimensions of the disc are 10" diameter, 3 1/2" bolt circle, and 1 1/2" height from the disc to the top of the hat. Any help would be greatly appreciated

    Default Ralt RT-5

    My Ralt RT-1 used a (much modified) brake disc from (if I remember correctly) a 70's Audi 100LS, inboard front brake, automatic transmission model.
    Car only sold for a few years.
    I tried finding stock for someone else 10 years ago without much luck.

    If they are VW wouldn't they be metric ? We used a VW stock part on a Wheeler SV, they were free out of their scrap bin.

    Default Ralt

    These are a much modified brake disc. Material off of one face, some more from the hib face, pin pattern, etc. The rule only required it come from a part the VW used (Porsche, Audi included). Thus the later RT-5 use of calipers (4-piston?)and brake disc from some other obscure usage.

    Default Ralt brake disc

    That's fine for VW numbers, but I'm pretty sure it's a modified Audi part.

    I used the Audi 100 LS rotors on the Zink FSV and other versions of the Zinks in the late '70's and early '80's. Later I gave up and made aluminum hats and simple flat rotors to replace the Audi parts.

    If you can't find the proper rotors, you might give Richard Pare, ICP, a call. He can certainly make a substitute. He has blank rotors cast that can be made to fit a lot of applications.
