No gains there Trunk lid and doors are steel, might save a couple pounds there, but not 50lbs. Maybe 10-15. Fenders and roof are steel, but very thin, you can probably lose a couple pounds there too.

Point is, this car is very light as is. Throwing aluminum at it might not change much. Keep in mind also that this car is over a foot longer than the ND Miata, and that’s almost all in the wheelbase. There is nothing out there that is RWD and this size that is lighter than this car.

i like steel. it doesn't fatigue like aluminum can. the audi r8 had a significant problem with that...

Didn't the gen1 Cayman GT4 have problems with the aluminum strut tower too?
