I wouldn't even know where to begin, but if some smart person wants to make an RF Miata, I have this one in the garage and we need one for Assetto Corsa. Actually the mirrors are body color now, this picture is old.
An ND2 in a "Step 1" version with better wheels/tires, coilovers, and a light engine tune would be great also. There's a surprisingly small amount of Miata content out there.
