Doesn't believe in dynos????
I'm sure it would be a lot quicker to tune the car on the dyno, rather than on the road!
I'm not sure what twin plates are like for track work, though mine came over from Japan with a twin plate and a brake cylinder stopper, which made me think that maybe mine had been used for track. So maybe you can use them for that. They just bite really hard that's all, and I'm no expert but maybe would be able to withstand the power better than a single?
Feel free to correct me if I'm wrong!
