Stance coilovers and 1.5 or 2 way clutch type diff

I'm no expert, but miata's with their short wheel base are kinda horrible cars to drift. they're great fun in the rain, but you can't keep the back end out real easy.

didn't they make a 240sx convertible?

miata's are great for the amature drifter, and yes they made a 240sx convertable.

I had a great time drifting, I suck but it was fun. The Turbo helped, But there was an NA who was really good. The best guy was in a nice 240 the second best was the other miata. Atleast I can say I made the most smoke.
