Jay, just seen this... Man up dude!
You can get some 2mm shim spacers from Halfrauds for about a fiver to clear your brakes. You won't even know they're there.
Also if funds are tight either buy some part worns for them until you can afford a full set, or sell your 370 wheels, and buy Tyres with the proceeds. You can then pickup another set of 370 rims at a later date when you're flush again (preferably before winter ).
For part worns, checkout eBay. I've bought 2x Goodyear eagle f1s off eBay over the last year. I paid less than £50 for one of them with 5mm tread left. I forget what the other cost me but it wasn't much more.
As for the refurb, I've seen BM's wheels and the finish is great - you can't go wrong for the price. And again if cash-flow is your issue, wait till winter when they're off your car.
...and you should deffo get the centres done in anthracite like mine.
