hello everyone, a question bought some 19" range rover sport alloys, they fit on my 1999 P38, and now the whole car has started to vibrate, i have balanced all 4 wheels tyre pressure at 32psi (now) i have also put fronts to rear and rear to fronts but still this vibrating, is there maybe a fitting kit? when fitting the wheels i needed to buy sport wheelsnuts as the P38 ones where slightly bigger,can anyone help? will be appreciated thanks
