fancy doing silverstone GP circuit track day but worried about running out of gears / revs, think we have standard ratio's in, what should we use (SR3 1550)

thanks

The fastest bit is Hanger Straight, where you will be getting 140+ mph, so the standard final drive ratio should just about be OK - but does it matter on a track day?

I did assume that if you reached peak revs before the next corner, you would lift off - easy for us as we have an analogue rev counter as well as the lights. Powertec do say, however, that you will damage the engine if you activate the rev limiter too often. We are getting 140 mph+ along the Hanger straight but you well might be faster than us, especially if you get a banzai exit from the Beckets complex.
