I have a SL 63 naturally aspirated with a wide body kit.
It also has a Programmer lowering device. I have a big almost dangerous
situation. Every thing is fine up to 70 mph, however when you push on
towards 100 mph the car bounces over bumps to the extent that you feel
you are going to loose the car. I suppose on a completely flat road it might
not happen, but even motorways have bumps and I am now scared of
taking it over 70 mph. Does any one have any idea how to cure this.:

Ride in the highest ABC setting you can when you are going over 70 mph.

Why don't you simply leave the car stock?

The cars from the factory drive very well up to 180 MPH and more...

Or is your car only for parking in front of the ice cream parlour...
