Chris can you do dry carbon or only wet lay?

'Dry' carbon, or pre-preg carbon looks better than shiny wet layup carbon IMO but pre-preg can also be lacquered to look as good as the Seibon carbon without adding too much weight. The lightest wet layup bonnet i've seen was 10kg, the same weight as a standard bonnet so other than looks, there's no advantage to fitting one to any race car. Prersonally, when i see dry carbon on a car i see 'lightweight' and serious competitor!


To explain wet and dry carbon: Wet layup is where the mould is coated with a thick layer of clear gel then a section of carbon matting has to be 'wetted out' with resin on a flat surface, laid into the mould and the air rolled out. All subsequent layers are done the same way and it's difficult to lay it up without using lots of heavy resin. Pre-preg is the same carbon matting but it is already impregnated with a heat curing resin - only just enough to do the job so it is much lighter. The pre-preg is laid into the mould and built up in layers then it's vacummed in a bag and baked under vacuum in an oven until the resin sets.

The difference in weight is like day and night TBH and although easier to make the parts in pre-preg, the materials and time to make a part are much higher than wet layup hence the higher costs.

The main defference is - wet layup bonnet 10Kg. Pre-preg bonnet 2.5Kg
