Just had my lower torque mount changed for the 'new/revised' one and it's made a big difference!
Notably the gear change is better and coming on/off the throttle is more precise in fact the whole thing feels kinda new and tight.
I used to get a mechanical 'thunk' during low-speed gear changes and that has gone now. Grabbing hold of the middle bit of the old mount it was really easy to bend it back just with my fingers so it's way too soft even though it wasn't actually split or anything.
Well worth the £25.00-ish for the mount, got my mechanic to fit it - he said it didn't take long, had to take the undertray off for access.
