Finally got the '90 Mini out at the weekend and noticed with the windows down that the suspension is really squeeky over bumps! I haven't noticed this before, but this is probably the first time it's been out in decent dry warm weather. We're new to Mini ownership but I've heard this is pretty normal, is there anything I can do to quieten it down? Not sure if it's the rubber cones or some bushes somewhere (rear suspension has been greased)? Maybe a good squirt of something might help and if so what - silcone spray, Plusgas, WD40, something else?
Cheers,
Tim
