420 Wheel Specs

[ianashdown]

Hi,

 

I wonder if anyone knows the inset/offset dimensions for the Caterham 420 13” diameter, 6” and 8” wheels.

 

Also, what do we believe are the lightest 13 x 6” & 8” wheels available in the US?

 

Thanks,

I assume you do not have these wheels to check the marking. I think it is 23-24mm offset (23 or 24ET marking on the wheels) for a back space measure of approx 4.5f/5.5r.

 

Lightest in CONUS? Probably aftermarket 3-piece with magnesium centers designed for no lug cover at around $3500/set. Cast or forged 1-piece with minimal center mass (spokes), 13x6 all around with less rear offset (near zero?) on the rear (bringing the tire outside edge to the same position as the 8 inch rim) would be much more practical and probably cost about $1000/set.
