Hello mate, this is a tad random as I had my cars MOT on friday and guess what I am also running the H&R cup kit, and I had an advisory for the front offside shock slightly leaking oil, weird as I bought the kit roughly about two years ago brand new and havent done much mileage on them,other than that the car flew through ok. Think Im going to ring H&R uk directly and see what they say to be honest or its coilover time.
