Just had some of the AS performance gear linkage bushes fitted to the car and its completly transformed the gear changes on the car. The gear changes are so much more percise and the whole thing just feels solid. I've always found the gear changes on the subaru's have been a weak point on the car but these completly change that making the driving so much smoother and enjoyable. It replaces the rubber bushes in the gear linkages with solid nylon ones and it takes out all of the sloppiness of the linkage. Definetly worth doing for anyone £60 is a bargin for such a big improvement.
