I see the Hellwig pro touring swaybar doesn't have greaseable bushings like some of the other rear axle mounted swaybars. Would it be worth it to purchase greaseable bushings or would it be a waste of $ ? Also would the swaybar work better if you replaced the adjustment link to something similar to what HR uses (to eliminate any binding that may occur using poly bushings ) or at least replace the upper half, just a thought. What do you guys think. Thanks,Kyle.
