Hi Brian,
I'm surprised at your bad experience, I've had mulberry bearings and springs on my last two mogs, a plus 8 and a plus 4 both were improved incredibly, the 8 was almost like it had power steering the difference was so great, lighter steering and nice and easy to drive.
The plus 4 wasn't as noticeably better as the front end wasn't so heavy, but the higher rated springs which spanner juggler fitted removed the front end crash which happened every time I hit a pot hole (inadvertently) in the plus 4.
Made the driving of both cars so much nicer for me.
