A buddy of mine got a set of H&R springs when he bought his used R53. How much would it cost in labor to change all 4 suspension and can he use stock Mini Cooper S shocks with H&R springs? My recommendation will probably be to change the shocks since they're probably quite worn out by now. What shocks do you guys recommend for an R53 with H&R springs? Koni FSD, Koni yellow, Bilstein Sport? Thanks guys..
