@ Gus,it 1st happened to me over 15 years ago!!! I even put a post and pictures up on here about this problem years and years ago.No one back then had it happen to them,and that included Tim Butcher,Ollie out of NMS or Christian and Beccy.
I used to just keep replacing them as I broke them,and I never heard or found a cure,as I was the only one who drove a rst on track that was having the problem.I actually thought that maybe my front suspension or something was'nt right,as these guys with 100 bhp more than me never had an issue!!!
