Cheers for the offer PeterRST! It's okay though, had a look on caprisport and whats on my capri. Identified the front set up as as the GTR 280 system using Granada front callipers and RS Cosi discs, and the rear as a Granada/Sierra calliper conversion. Looks like someone has had a fair bit of money put into the brake system on this car (only a few quid less than I paid for the whole car!). You have both been a great help, now I can start saving for some new 15's with a bit of confidence. When she looks nice I'll try to get up the before and after resto pics (will PM you if I fail lol). Thanks again!
