are you getting one of those flyin miata kits. My dad asked me if i wanted a car to race i could take my moms 2000 mx5 miata and turbo it and install a roll cage and all and drag it or auto x it. but yea they would make good sleepers cause im pretty sure people arent expecting a turbocharged miata to pull up next to them.
I drove one of those mazdaspeed miatas a few years ago they only have 178 hp but man when that boost kicked in i was pushed into the seat lol. those cars are like go-karts
