Brake Rotors: S I-V

[Sunbeam Canada]

Question #1: Anyone able to confirm if the Alpine brake rotors are interchangeable.?

Question #2: In particular, will a S-V rotor fit a S-I?

Question #3: Finally, any information on modern rotors that will fit a S-V would be appreciated. Ideally, for racing.

I'm pretty sure they are all the same. If you do interchange rotors, they need to be checked for run-out. I think the tolerance is a few thousands only.

The Rootes Part catalogue states as follows:

Part# 1201249 S I and II
Part# 1206249 S III and onward.

The manual does not explain what the difference is. ??

I want to donate as set of S-V rotors to a local S-I owner however, before he takes on the task, we need to be sure of the match.

I was under the impression the SI/II rotors were smallewr than S3-V, thought it was 9.5 vs 9.75 or .85?

Ohan, there are several alternatives listed here.

Thanks for the link Jeff.

Is there not a modern/alternate vehicle rotor that can mate with an Alpine ?

As in a bolt on over the counter rotor from some other car?

Not that I have ever heard of, but Bill B. made a set fit along with different calipers.
