Have a look at Si's (Foxspeed) car, he has got colour coded mud flaps and they look really good IMO. I think the problem of gravel rash is more from the crappy roads we enjoy over here! Every single one around me has been 'resurfaced' which involved dumping loose gravel on the road and leaving it for 2 weeks then pouring tar over it along with more gravel.
Needless to say Im not a happy boy! :swear:
