If you stick with 235 tyres, I don't think Devonports can ever look at their best without spacers. I'm at 25mm/25mm. It looks spot on imo, without looking too aftermarket(ish) or dare I say boy racer-ish
, which suits me. I user to have 40mm on the rears of my T5, which I liked for a while (call me Carlos Fandango), but after a while I thought it was too far away from an OEM style solution, which is now my preferred style.
