Hi, looking people's advice/experience on what gearbox or gear kit is best suited till circuit racing, currently have the uk 6speed fitted and running a 450bhp 2.1,but worried the 5th and 6th gear ratios might not be ideal, will mainly be competed on a "power track" with just the odd sprint type event, Thanks for any help in advance

6 speed all day ,but use on online gear calculator to see what ratios are ideal ,ie wheel/tyre diameter ,box ratios, final drive ratio (a 4.4 6 speed is avaiable )and engine set up, as in shift points /revs .
