I know I have said this before, but the BMW bolts tend to loosen up at track events, I have gone back to standard lotus lugs, I used lotus lugs torqued to spec on rotas, JL audio jim clayton used the bmw bolts on the same rotas torqued to spec and we both got on the track, checked wheels after cooling, lotus lugs did not move at torque, several of the bmw wheels bolts had loosened, requiried to be retorqued. I know that it is proper procedure to check after each track session, but many people do not. Just a heads up, anyone who feels that I am wrong show me some real world data as I have used the bmw bolts on ssrs; and stock wheels and now rotas. I do not know or care why they do this, just that if one of my wheels came off or a problem occurred it is too late. If stan can or will read this I am not an engineer, I am just a track/ lotus guy and I do not want anybody to have problems. Additionally I have sheared several of the bmw bolts, while torqueing them to spec, they might have been a little bit warm but it is not like I put a 100lbs on them just 75-78lbs.
