Could it be a design / lead time on the parts? I'd imagine that such an important part would also need a fair bit of testing before being raced. They've probably concentrated their efforts on the problem end of the car with a view to then update the front as time / resources allow.ArchAngel wrote:A case of "if it ain't broke, don't fix it" thinking? Perhaps attributing the problem with their nuts in part to the specific temperature & mechanical stresses that the rear wheels are constantly subjected to over a race?Crucial_Xtreme wrote:Kravitz reports that McLaren are only using the integral wheel nut system on the rear tyres, not the front. Interesting.
