Not wanting to stretch this thread out unnecessarily but I got mine back from Pete today and I am very impressed with the finish - shame it wont be visible on the car! Even with 3 brand new engine/box mounts I still have some on-off throttle movement of the motor so hopefully this will sort the slight rocking out permanently. Will report back once its fitted next week.
Ive gone for the slight softer fast road compound rather than the race.
