OK,
My supplier sent me the following email in response to barries nuts question
First on the wheels, new normal chromed nuts are approx. GBP6 for 20
nuts, but I asked the supplier to include these.
As alternative, they can also buy these special light weighted forged
nuts. You can get these in red, blue, silver, titanium color.
These are GBP40 for one set.
