Wish I got them fitted as your right a lot of crap thrown up from road with 20's. Not convinced does anything for the looks though, as nothing else except tyres match in colour.
Enjoy you motor it looks cool with those wheels Need to look at upgrading mine, as I can see laquer peeling already, argh!! >:(
Looking through some of my old pics and came across my E53 X5 4.8is. Loved that car. Only mod was M3 Steering Wheel with flappy paddles.. Worked well!!
