Geomaster 3 Rear: New improved version from Dec 2017 - Improvements in drop & kinematics. All new spherical bearings in place of bushes for less camber and toe deflection. Double brake caliper mounts, internal drum handbrake compatible. Improved overall rigidity. The new coating: We have chosen a zinc polyurethane process, offering impressive durability, and vast improvements in corrosion resistance. Please note: These are a racing part, and as such are not suitable for road use. The fronts require the top of the coilover moving forward to reduce castor because the tension rod must be shortened. This can be done by rotating a normal camber adjustable top mount by 120* (no drilling or modification required)
