Dr Mini has stated that he used to cut down the pads for the Honda setup to fit inside 10" wheels, but he's decided that it's not a good idea and won't do any more sets like that. That's good enough for me! Beyond that, most setups (not Camira) use the standard drum CV's, which could have problems, and there are only 3 x 5/16" bolts holding the drum backing plate onto the hubs. I've heard that Engineers up here in Queensland often don't consider that a strong enough connection for the caliper-hub plate to have. Don't know what they're like in SA. Those were enough reasons for me to decide that it wasn't the option for me.
Beyond all that, even if you could get around those problems, would you really want to machine down the diameter of your rotors every time you have to replace them? It might have been attractive back when Mini rotors were dearer (I once paid $175 for one 7" Cooper rotor - to make matters worse, I ordered two over the phone from one of Australia's biggest suppliers (at the time), who told me he only had three left, no more were being made at that point, and he'd send me two. Only one arrived, he called me and told me that he'd sold the other two to someone else. He wouldn't accept the one back. His excuse was that he'd never sell one, my position was that I couldn't have a car with one disc brake. I never bought off him again.
), but they're not that bad any more. I looked through the DBA replacement rotor database, and I couldn't find anything in there that wouldn't require machining. So the easiest solution is to run the S rotor, and, if you're running the S rotor, you may as well get the rest of the setup... You can get it for around $1480 ex UK (including freight).
Plus the rear slave cylinders, etc. Still a bit better than the local costs. If you get import it all in one hit, you'll have to pay Import Duty and GST, just like the local sellers (which is why their prices are higher, plus a little bit of profit, though they're pretty fair, there doesn't appear to be much in it for them). So the trick (not that I've done it yet) is to get it sent broken into a couple of packs, with a time difference between the two packs. I've asked an online seller over there about doing that, and they're willing to split up the pack.
$1480's still a lot of money, but it's not really that much more than discs for 12" wheels (but you don't have to buy 12" wheels), and it's not that much more than an engineering-approved alternative would cost - one which would either require machining or 12" wheels. And the higher cost has the advantage of being 100% new components.
