    Whats the difference?

    i'm looking at getting an UMI panhard bar, lower control arms and relocation brackets...

    i see there are non adjustable, adjustable, double adjustable, panhard bars...now what is really the difference and what is really necessary and overkill with these?

    same with the LCA, adjustable or not?

    The adjustable units are almost a necessity if you have a lowered car, or plan on lowering it in the future. This allows you to keep the axle centered in the car and wheels centered in the wheel wells. If you go with an aftermarket rear axle you can also compensate for any differences with adjustable suspension pieces.

    Our car will never be lowered due to our wonderful northern PA roads. Although I have an aftermarket Moser 12 bolt, I chose non-adjustable UMI hardware. The only exception is my torque arm which has an adjustment to set the pinion angle. I also have welded relocation brackets for more bite. FWIIW: The fit and quality of the UMI pieces is exceptional.

    This is what my setup looks like:

    From my understanding when using relocation brackets you need adj LCA's to keep the wheels centered in the wheel well because the mounting point has been moved back.
    As for the Panhard bar an adj. one is used to recenter the rear after installation of lowering springs but IMO it is a must because the rears are not centered correctly even at stock ride height. For the Panhard double of On car adjustable is preferred.

    theoretically the brackets should not move the rear back. the holes are drilled in an arc so that each one is an equal distance from the body side mounting hole. unfortunately some brackets don't fit quite right and/or people install them slightly incorrectly and it causes issues.

    Do you plan on doing it yourself or taking it somewhere?

    It's getting there. My goal is to make it half as nice as Preston's.

    It is our summer play car. I try to keep it out of the rain and crap, but living 1/2 mile down a dirt road makes it a challenge.

    Good luck man and if you need some help or a hand, hit me up on here. I'm not too far from you. I just got an adjustable PHB from UMI myself but haven't put it on so I'd be down for helping so I know what to do when I go put mine on.
