    My 2012 Kia has a USA VIN since is starts with 5XXGR. But the struts I ordered for a USA optima did not fit my car, see this photo you can see the strut mount bracket on the new strut does not match my OEM strut. So can someone tell me does my OEM strut looks like a USA or a Korean Optima...

    was about to put my new KYB struts/mounts in.. and noticed the "bearing" that comes with the strut mount seems to be 2 plates of fiberglass reinforced plastic.. they slide smoothly, but without any actual metal or ball bearings. I know that there isn't a significant load on this part, but still...

    Hey guys. Just installed my front strut bar but the bolts seem a bit off. I can't move the bar and it's on there pretty tight so that's good but from other pictures, it seems like the bolts were screwed on further down. Used a torque wrench at 40lbs. Please let me know if this looks right...

    [Just putting this one out there, since I have not seen any recent discussions on the topic.] I just installed a strut tower bar on my 2013 Optima LX, and I have to say, the handling has been dramatically improved! You won't really notice much at lower speeds, but above 40mph, this thing...

    Has anyone here changed out the trunk lid opening to some struts? So you can fit a couple of infinite baffle subs on the deck? I realize there are other sub options but that's not what this thread is about, so please keep on topic rather than suggest alternate sub locations.

  18. Wheels, Tires and Suspension
    Can you guys please give me your two cents on which tower bar is better. I'm looking at purchasing one in the next 3 weeks. Ultra racing or kinetic? Anybody have experience with either? Feedback is welcome please. Is there more benefit with the kinetic because it bolts to all 6 tower bolts?
