Hi, a mate has just bought a disco on a P reg and has put some doughnuts on the back springs to beef up the suspension, has anybody tried these, does anybody know anything about them, does it improve handling, is it better to do front as well as back?????? Regards Tots

they are called spring assisters. they were designed for use when towing caravans. theyre not a lot of use, all they will do is harden the ride
