I don't know why I'd never thought of this before. For people who don't know, my car shoots through the gears at a fair pace. At the Pod, I'm at the brink of crossing the line in 5th gear.
Now, theres two options, one is to push the power band up the rpm range a bit and the other is to extend the ratios a bit.
So, apart from Quaife is there anyone who sell gears and what kind of cost is involved?
