Huddie, depends what you are changing from. Also, why AVOs? Whats that wrong with SPAX or GAZ on the front of a 4/4?
As you live in Wiltshire, that's close enough to me (near Castle Combe) to try my 4/4 with the SUPLEX/Bilstein front suspension refinement system. Contact me on a personnal message if interested. Regards PJB.
