My other car is a MINI!!!!
I must admit I was skeptical about the 'hard bedding in' method, and took it easy for about a hundred miles or so on my DS2500's. tehy were truly shocking though, so I decided to go along with the advice, and went out to the motorway late one night and gave then some abuse, the difference was incredible.
You literally need to get smoke pouring off the front wheels in order to bed them in fully, it's a pretty scary procedure, but so worth while.
If you look on the box it talks about bedding them in on a track, and returning to the pits for inspection! You know you're onto a decent pad when they don't mention road use at all!
