Hi, customer dropped in a 1998 1.8 MGF roadster. When you drive it over speed humps ect the rear of the car almost takes off. Even small hump makes the car just up. It's fitted with hydrolastic suspension and not really sure how it works. I've had the fluid level check which was low but has been topped up now but still the same.

Does anyone know how it works or had a similar problem? Thanks Tom
