I already run a pair of these on the car but bought a second set in full black gelcoat and they're no longer required. The holes for the door blades are cut ready, but otherwise they're untouched. They are super lightweight and strong. Weighing only 4.4kg compared to around 30-35kg per door. Making a total saving of 51-62kg overall. Sadly, they're based in Sweden where I live...so may not be interesting to you UK peeps! £400 the pair without shipping.
