Ive just had my 150 Sigma flat floored at PGM Motorsport in Patridge Green in Sussex. Car now feels a lot more planted and controllable on the road. A job well done.
However, the reason for my post is to find out if there is a cure for the Kangaroo effect at low speed and revs on my Superlight. I dont think having to slip the clutch is the way forward and the constant jerking backwards and forwards is not doing the diff any good. Therefore, have other people experienced this issue and found cures for it. It has been suggested that a plenum body and lightened flywheel may be a cure but im interested in the combined wisdom of the 7 membership. Thanks in advance. Todd.
