Rear end help...

[chodjinn]

SD1 axels are pretty easy to convert to discs from drums, I'm running a pair of Sierra Cosworth calipers on the rear with built in cable handbrake - they are available off most sierras/granadas.

I would not recommend you plan to start with a RV8 then Chevy, stick to one and go with it, for ease and expense reasons if nothing else!

What discs did you use? Presumably vented if for Cosworth callipers?

Dave,

I believe they are Mercedes discs that were ever so slightly redrilled to suit.

And they are solid discs, only 4x4 cossys had vented rear discs.

Ah. Most SD1 rear disc conversions use modified stock discs - not racing parts. To keep costs sort of half reasonable. When I looked at it, racing discs and adaptors would have cost about £400 including the necessary machining, before even thinking about callipers and brackets.

'Racing' discs are not that expensive per se. I'd speak to someone like Reyland who could produce some bells relatively cheaply, they all you have to do is replace the actual discs rather than the whole thing.

Well, that's what I'm planning on doing long term anyway.

When I looked into it, plain bolt to a bell racing discs were about four times the price of a similar sized production car type. Before the cost of the bell. That was from Burton.

From what I remember there isn't as much depth on my brake rotors as those bells. I'll have to check but I'm away this wkend.

Hi
Having said to avoid 9" axel in the first instance, there is a 43" wide 9" ford case on eurodragster at the moment for £100, not much said about it but if it is a factory case a bit of bracing might be needed for anything over about 850 bhp otherwise a cheep way to start you collection of bits
Best regards
