with maranello, only interested in formula one, facetti and finotto decided to take on all-conquering porsche 935s, even though their facilities at archille motors was hardly equal to porsches. they chose the 3.0 liter ferrari 308 gtb as their base model. as group 5 was a silhouette formula, facetti know he could change a lot of things provided the car looked like the standard road version. this car they called carma ff {carlo facetti and martino finotto and the ff for facetti and finotto}.
