just had this done to my rs mk2.made 400hp and 440lb ft of torque.could do little more but jamie at jamsport left it a little shy cos clutch and flywheel would need upgrade to maintain reliability.they also did bushes on front arms,torque link and adjusted geometry.figures dont say much but i can say rs is mindblowing on road.simply pulls like an express train and handling transformed by changes.pay these boys a visit.they are just ace!!!!
