A very simple and reliable way of advancing the cam timing is to fit this modified and adjustable cam sprocket. By simply inserting a precisely calculated offset disc, the cam timing will be securely advanced to the set figure on the disc. Quick and accurate changes can be made (without the need for timing equipment) to optimise your power characteristics either at the dyno or at home.
     Standard road cars are generally set at a figure which caters for all types of drivers, but if you advance cam timing it livens the performance for quicker throttle response, more revs and more power! Also when the cam chain stretches with wear this also retards the timing and reduces performance. If you skim your Cooper head on a rebuild this is a must to regain the cam timing and performance. This kit comes complete with the full timing chain set- 2 guides, crank sprocket, chain, tensioner, modified cam sprocket with a +2 degree and +4 degree discs. The most reliable method used in racing.
