Be a bit wary of what some UK alloy wheel resellers recommend right now.
With CV-19 TUV tests will have been scaled back along with everything else in the world of alloy wheel production, design, logistics etc etc.
A site such as felgenoutlet.de will have properly approved sizes for use on the German market which is the best guide you can get.
It’s early days with modifying mk8’s and Covid has thrown massive spanners in the works all round (stating the patently obvious).
I severely doubt whether some of even the most established UK wheel resellers will have even clapped eyes on a mk8 Golf Clubsport yet so wouldn’t be able to absolutely guarantee that the inside of the spokes would clear the brake callipers in certain offsets or whether wheel balance weights situated in the middle of say an 18” wheel would have enough clearance of those callipers either.
Until more people have physically attempted fitment or TUV publish results it’s all educated guesswork.
I’ll stick my neck out and say that anything that will fit a mk7.5 TCR will fit a mk8 Clubsport and anything that fits a 7.5 Performance will easily fit a mk8 245.
It’ll be a while before I fit my own 19”ers as I need tyres and in the spirit of lockdown it’s not right to drive miles to get them fitted (once I’ve decided what I’m buying rubber wise) whilst I have another car at my disposal for commuting.
In simple terms, the higher the number offset the more it’ll sit into the arch. But an offset of 45mm on a 7.5” wheel will obviously sit quite a bit further in than a 45mm offset on an 8 or 8.5” wheel.
