Spoken like a true Anorak! [] []ORIGINAL: Rodney Naghar
Did you know that the lightest part of an alloy wheel is where the valve protrudes out through the hole. Therefore Porsche has designed the locking wheel nut to compensate for the weight loss and should be placed at the bolt OPPOSITE the valve hole! I've read it in the 993 manual, although I'm not sure if this is still the case with 996/997s.
But that's only true up to MY1996. After that, it was optional. (Yes, I'm serious!)
No such requirement on 996 though.
