I just purchased a 2013 i135 M Sport convertible. I have about 3300km on it so far. I have just added the JB4 programmer and am wondering what else to do. On the twisty roads I have noticed a great deal more suspension dip than on my old Z4M. Has anyone tried the cross bars and if so what was the end result? Did they help much or have you had to get a whole suspension?
thanks in advance for any help/advice
