I don't know about Jax but most tyre franchisees don't do squat when they do an alignment, caus care factor = 0
If you want the best alignment, advice on how to get more camber, suspension setups etc, its worth travelling to Centreline Suspension in Thomastown. They are 2 mins from the Western Ring Rd, just off Mahoneys Rd
