Not great. Pros. light weightm made from Durralium, they are about a 75% weight saving over std Choice of colours Okay design of locking key Cons Expensive £100 for a set Paint colour chips way to easily To soft for motorsport, twice I have had ones strip. and thats not using air tools Locking nut too easy to defeat I change wheels and tyres twice at most races, these just dont cut it. They are style over substance
