RA28 5 stud front discs

**Bazooka** · 03-09-2010, 11:32 AM

I am trying to get all the parts together for a front brake upgrade to the RA28. I already have RT132 struts, MS65 5 stud hubs and Hilux calipers. I know the disc used with the 4 studs are the Peugeot items but does anyone know what can be used when converting to 5 stud?
I have a Hilux rear end to complete the 5 stud conversion with MA70 rear discs.

Cheers

I used the Peugeot rotors redrilled to 5x114.3.

That was a thought but DBA no longer make that disc. I am looking at a Ford Transit rotor which is close and 5 stud. This is also 24mm thick which will accept the larger Hilux/Surf caliper but I do not know what sort of wheel clearance I will end up with?

Unfortunately that rotor is too narrow and too large in diameter. Also at 26mm thick even the Hilux caliper would have trouble fitting over it.
I have ordered the Ford rotors so will post the outcome when they arrive.

Just to follow this up I have received the Ford rotors (along with the Supra rears) but as I ordered slotted discs the brainiac at the store ordered in all left hand side items.
Now as I am waiting another week for the right hand side rotors to get made I decided to fit up the one good Ford item.
I was pleasantly surprised to find that these rotors had all the required dimensions. The only thing that doesn't quite match up is the fact that the mount holes in the rotor are threaded. As the holes in the hub are also threaded all it took was to drill the threads out of the rotors holes and run longer mounting bolts. All fits up perfectly thus far.
I have not yet been able to test fit the Hilux caliper over this as I could not find my calipers. They seem to be buried somewhere in my shipping container. The only concern now is being 270mm the Ford rotors may be just that little too big being that the standard disc is 266mm.

Well I am pleased to announce that the above combination works a treat.
Using the Ford rotor I had the MS65 hubs machined and a spacer made to fit the 70mm centre hole of the disc. I found the S13WB Calipers to fit over these exactly without the need to machine them down and bolt up to the RT132 struts.
My only concern now is that these calipers having the fins on them do stick out rather far.

Does anyone know if these fins can be machined off to give extra wheel clearance?
