My Dax is a Sprint and Hillclimb car. It gets quite a bit of grief on track as I am very competative ! But not as much grief as a rally car or circuit racing machine. At the moment I am looking more to the Quaife based on the fact that they are pretty well proven and if I come to sell it at a later date it will probably have a better resale value. Also because its an engine out job to change the box I dont want to have to pull it back out to fix it too often ! I know some of the other makes are probably better but my budget is really around the £6K mark. Sprint and hillclimbs are fast and furious but range from around 37 seconds Crystal Palace to 94 seconds Goodwood so relatively low usage compared to other motorsports.
