Hi Tony. No, no changes to the suspension at all. I think it was just down to using an old and very worn set of 888s that were pretty much slicks. They had been stored for the last 6 months or so in a garden so were somewhat weathered as well as badly worn.
When I swapped to the Avon ZV3s it performed perfectly and the balance was spot on allowing me to really take liberties, especially through the kink/chicane onto the main straight.
