Ally wheel nuts

[grahamb]

Ally wheel nuts: Are these outlawed? Cant find the regulation in the Blue Book myself, but have been advised that they're a strict NO for Racing.

Just converting from bolts, to studs-and-nuts, to ease wheel changes, and came across alloy nuts on 'that internet.

Technical Regulations

46. All Sprint and Hill Climb vehicles must comply with
the following:


Wheels and tyres
54. Nuts securing road wheels, except those of centre
lock type, must be made of steel and have a thread
contact over a minimum length of 1.5 of the bolt/stud
diameters. Extended or composite wheel bolts/studs
are not allowed.

I machined some nuts to get within the 1.5 rule and got pulled the first time out and told to get it sorted before I came out to play again. Cost me a set of longer studs, could have been an entry fee and travelling money.....

Try not to think of it as just extra mass.

Think of it as extra downforce!

Happier?

Red, i am suggesting reducing the waste diameter, (grooves etc) but yes its totally over the top and best left as standard,
