We did mention this type of thing on another thread, think someone had guttedly kerbed a wheel. From memory nobody had any experience of them. From the link I see there are various adhesives and mechanical fixings, question is would I be happy applying those ti my 22" Black Helix wheels?? And if I did kerb one how easily are they replaced. I saw something similar yellow ones on a chavved up VW whilst on holiday last week......I think Stevie Wonder must have fitted them......they were wibbly, wobbly around the circumference. Think I'll take my chances and go bare and use my driving judgement and the cameras for anything closer.
