There are several alternative suspension kits available for the MGB. The first on the scene was the Ron Hopkinson kit, from Derby MG parts specialist (now ceased trading when bought by Moss). Created with help from Harvey Bailey, a well-known suspension tuner, the kit involves the replacement of the front anti-roll bar with a thicker one, and adding one to the rear suspension. (A Mk2 version with improved link arms and joints is available)
