Cosworth brakes
Has anyone got a set of 2WD Sierra Cosworth discs either on a car or in their garage. Trying to identify whether these are what I need on my XR2,
which is fitted with Wilwood 4 pots.
I understand they should be 283mm diameter by 24mm disc width, but I really need to know the offset, and the thickness of the 'hub' part
to be sure before I splash out.
If anyone has a set they can get to easily, it would be appreciated if they would take a tape measure to them for me!
Cheers, Chris

Thanks Will. I need 283mm discs though. The 2WD Cossie had them, but I'm not sure if the offset is correct for the calipers I have!
Tom - excellent tip, thanks. Just a shame I can't work out what all the numbers mean, or find a diagram on the website. Have emailed them
though, so hopefully they will write back and tell me!

Not a very helpful reply, but I can assure you that the cossie 4x4 ones are different, so don't use the measurements from those. The 2wd ones
had a greater disc offset, but I scrapped the pair I had laying around a while ago unfortunately.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

Well, I've come to the conclusion that Brake World are in fact idiots.
What a wonderful idea to put the catalog online with all the dimensions so that it's easy to compare discs and work out which ones you need for
your application. Would be fantastic.... except half of the numbers don't seem to relate to the disc, no matter what I measure, and they have
completely ignored my email request for an explanation.
What's the point in going to all that trouble and then miss off such a valuable piece of information? 
Anyway... rant over!
Chris
