Carbon: Ehh, depends on a car as well..
try to hold open the hood of a mkIII supra T...its heavy...
now a stock one on (92) Miata... ...feather
so depends on the car...
Rice: Hmm...so 17s+ on your car is "Rice" ? since there is no real function, (not the 13-17lb racing ones) but it looks a helloafa lot better than stock. (well you could be running 18s to get the BBK to fit)
In the end it comes to opinions, what YOU like, and what YOU think.... and if you have someone to agree with what you think that does not make it a definate, just that you're not the only one that thinks that.
just some thoughts
