Well i kno that regular carbon fiber hoods are sold but im looking for some with a vent or an extraction of some sort for a 1990 anyone kno of any sites??
Be wary of CF hoods for Miatas. Miatas have very light aluminum hoods as stock and most aftermarket hoods, even CF ones, will add a lot of weight to your Miata. Weight is the enemy in a low-horsepower, high-fun car like the Miata.
