Non adjust panhard bar & Lca Not lowering ?

I'm playing around with the suspension on my newly aquired 90 GTA. New Sway bar bushings end links, wonder bar, subframe connectors.
I have no intentions of lowering the car ( it's fun enough getting out of it and my 01 ) Height is fine to me.
Would the non adjustable panhard and non adjustable LCA's be of any benefit? ( poly/poly)
Thanks ..

The standard npn-adjutable rear LCA"s & panhard bar would work for you. I have the non-adjustable Spohn parts as a upgrade from the cheap factory style.

My personal opinion is leave the adjuable stuff to the guys who like to turn wenches all the time.

Do you have any issues with binding? I have heard some say they have issues with binding due to the poly/poly bushings. I'm not running major horsies ( 305 TPI ) But just want a good solid suspension.

Zero binding issues from my UMI pieces.


On my GTA, despite my stock PHB having poly bushings & the car still riding at stock height (no lowering or worn out springs), my rear axle was offset to the drivers side by almost a full inch. If I had wanted to stay with stock 245-sized tires, that woulda worked fine. But to fit my 315s, I needed the adjustable PHB to get the axle centered correctly to get both sides to fit.

I was looking at the UMI stuff.
How would your rear axle get out of alignment almost an inch? Hard drivin?

No clue. My bushings look good. My mounts look good. My bar looks good.

So I dunno what was causing it. But my UMI piece sure fixed it!

Re: Non adjust panhard bar & Lca Not lowering ?

Not a problem. I used a string having from each fender lip (with a washer tied on the end) to see the difference & adjust the UMI piece square.

If your staying with 245s, you probably won't even notice the difference enough to bother you. I didn't until I put 285s on & was ready to do the 315s.

Shouldn't be a problem. There is plenty of clearance for 245s.
