DONT fit wheel spacers, esp. that thick if you dont want to have to change your wheel bearings every six months...
b****cks. I ran 25mm hubcentric Spacers on the rear of my TT and 15mm on the front for over 20k miles and I didn't have one bearing let go.
I'll be going 15/20mm rear and 10/15 front on my 172.
Depending on wheels will depend on the size of spacers you need anyway.
In terms of wheels though... that's really a personal preference mate. I'm loving the Euro/JDM look at the moment and I know Rota's are hated but some 16x8 drifts (i think they're the drifts!) look superb imo and as you'll need pcd adaptors they'll act as spacers! Win Win!
I'm not too keen on many after market wheels atm tbh, some Keskin KT1's 16x7.5 and 16x9 rear would look cool.
As I say though, depends what you like! You might want 19" Chrome Spinners!
