so i can't bear the steering wheel shaking anymore.. i have 20mm v2 ichiba spacers on all fours.. rotated all tires, flipped and rebalanced all four (no road force balance done), checked and torqued spacers and still the shaking persists on 60mph-70mph.. it goes away at 80mph ( none at 90mph-120mph :smile (2): ).. now i can't be driving 80++ mph all the time, so i took off the fronts but kept the rears on (vibration is gone).. any cons? awd but i know that it becomes rwd biased after 30 or 40mph.. never had this problem on my g35 coupe before ( i had 20mm on all fours as well).. i have stock 20's.. lowered on h&r..
