I think the FIRST place to start is to verify the tightness of all suspension components. On my Esprit, Lotus specifies that as part of a B Service, and I do that every couple years or so.
When I first got my Lotus, some of the control arm mounting bolts were not tight at all! At that time, I loosened them all, weighted the car with two simulated 'passengers' as the service manual says, and tightened them to specification. No issue since.
I know on Elises that the rear suspension especially, needs to be checked regularly.
Also, check for deteriorated rubber suspension bushes, and play in any ball joints.
