I agree. I was curious about the weight savings, and weighed the following stock (on a GT) then their carbon fiber replacements to calculate the savings (all replacements from CarbonFBR):
Three GT heat shields: -297 grams
Mid heat shield: -143 g
Left radiator upper trim: -43 g
Right radiator upper trim: -45 g
Front fender: -35 g
Front fender supports (combined): -65 g
Airbox trim piece: -107 g
Final drive heat shield: -44g
Total savings: 779 grams
Meanwhile, replacing the catalytic converter with a Werkes exhaust dropped ~10,400 grams.
As for carbon wheels, well, every friend I've had who installed them shattered them. No thanks.
