Cheers for that mate ^
My back ones are a 9cm gap and the fronts are 8cm
So lowered 50mm on the back, 45mm on the fronts. I thought it was loads lower on the front.
If anyone has any (or could get any

) measurements for the centre of the centre cap to the arch that'd be great. Mines 31.5cm from the centre of the wheel to the arch on the rear, 30cm on the fronts.
