Ahh of course I forgot that bit, but chances are if you want a decent 4 pot brake upgrade you'll need spacers or different wheels anyway.

So why not the Sub8 brakes and spacers? I'm lucky enough to have got the sub8 wheels if not the Sub8 pack.
 
As said it has 19" wheels but they are different wheels. the OEM original Cupra 280 wheels wont fit big brakes behind them.
 
In pictures I always preferred the original wheels, but in the flesh I preferred the Sub8 wheels. Just as well as that's what the car had been speced with. No Brembos though :(
 
I'd of thought the sub 8 brakes would be the same caliper as the TTRS brembo's,you can buy the reconned calipers on eBay in any colour for £350

I'm sure the likes of AKS tuning will make a carrier to suit the golf R which will fit the seat then it's probably just a case of fitting the correct spacers
