As someone who has owned four Miatas in the past 10 years, including a Spec Miata, I also concur.
I also instruct for several High Performance Driver's Education schools, and if you've never been to a track before, I promise you that I can lap you with a Miata no matter what car you bring.
As someone who has ridden a bike for 10 years, I can promise you I can beat you in a race if you have never ridden a bike before....
But seriously, I can't even fit into an MX5 (as they call them in Europe), I'm 6-2 and 260lbs. And I'm pretty sure if I did fit, I'd be lagging behind due to the power to weight ratio suddenly falling through the floor carrying my fat ass around.
My track car of choice is a 2002 Audi S3, spent quite a bit on it already. Running around 300bhp at the moment. Considering on ripping put the rear seats because if I get 4 people in the wheels rub, so might as well get rid of the seats!
As a 6'0" 175lb person, I can imagine...
Also, neat that there's two spec miata racers here! Did I bring you over from miata.net or something?
