Hi guys,

Searched web without an answer to this.

I have caliper adapters, calipers, GT discs etc etc to put onto a Euro S2

Problem: S and S2 brakes have bigger calipers than original 928 (larger distance between mounting holes). The only caliper adapters I can find require to change the spindles for early (pre-S) so the caliper adapters can be used. This is fair enough BUT early spindles have no possibility of fitting ABS sensors !

I have searched the web but cannot find any caliper adapters available whereby S4 calipers can be fitted to S or S2 spindles. I don't know why this is.
The issue is only that the mounting hole spacing on S / S2 calipers is wider apart than pre-S as far as I can see.

So, for 84 S2 I need to find these adapters if they exist. The alternative is complete S4 front hubs / spindles but this gives another problem, the ABS ring on the hubs has more teeth on an S4 than an S / S2 and are not therefore compatible with the S2 ABS ECU. There may be big wiring issues involved !? Also the rear ABS rings would have to be S4 too and that means a whole load more parts, including rear hubs and all four ABS sensors as these are also different.

Does anyone have knowledge of how this can be achieved, or a source of caliper adapters for an S / S2 ?

Thanks and regards,
