The manufacturer ask me to not give the price I paid (because it was the first he made and we had arrengment, so he must set the real price)
you must look with him and it will depend of the option you choose
mine is fiber/carbone for road use, so reinforce like the original bonnet and with all the original fixations
you can have lighter and cheaper one but you will need race stile fixations
you can also have one full carbon but more expensive
in any case it's realy good quality product ! (the under part is just amazing, actually I think of make varnishing on top for final perfect look)
