You're talking to a non-mechanical person here PJB. You might as well have said 'fish, trumpet, penguin'.
Is the kit you've mentioned above, part of the same package and will it remove the need for any greasing?
I don't have huge confidence at speed in my Roadster - it wanders over undulations and is a bit unsettling. So a better suspension set up combined with no greasing would be very appealing.
