Price about to be released. There is nothing that difficult to fit the system as it is all bolt-on, no new holes if the car has a damper hoop except may need holes for the Panhard cross member. Access is needed below the car ideally and care is needed to make sure the axle is true and the corner weights are OK. So DIY is not that difficult, but I am sure dealers selling the kit to a customer would want to be sure of the customer's abilities. Regards PJB
