depends what you define as best. Best to me is a b&m quickshift but they are rare as rocking horse sh!t and because of that quite pricey. Your next option would be a puma/zetec gear linkage. This isn't a quickshift however a good improvement on the mk2 linkage. The last option would be an adapter plate you can get from the likes of orbital Motorsport which moves the linkage slightly.
