Default Rear spring ride height-----

How low can you screw the rear ride height adjusters?
Can the spring touch the knuckle?

Dont screw past the hole as it will become a weak spot on the bolt and could snap it.. They have long bolts that are about 20 dollars from
Ecklers for doing this..

I was thinking about doing this myself, getting the lowering kit that is. How hard is it to do this?

Default lowering kit

What I installed is the full VBP suspension kit.

How far can you screw the bolts down?
Can the spring touch the knuckle?

I saw that you asked this twice, but I don't quite understand the question. Help me out here.

I don't think the threads on the new VP&B bolts are threaded far enough for that to happen.

Now, I see. Thanks for the photo.

Actually, lowering the rear moves the spring away from the knuckle not toward it. So you won't have to worry about clearance there.

I dissagree.
Look at the rubber washers on the top/bottum, and the width of the spring.
If you screw it all the way down it will tough the knuckle under the centerlink.
My question is-Is this a problem?

I have all new VBP suspension. Installed rear first as it was the easiest then went at the front. When we set the front down the car is VERY VERY VERY Low in the front and the rear looks jacked-up. Just curious how far I can go on the bolts-------

Then your rear suspension must be dramatically different than the suspension on my 86. I can take the NUT completetly off, allowing the spring to drop all the way down. The only thing is comes close to is the bottom of the wheel.

When I lowered the passenger side of my rear, the spring moved away from the knuckle, not toward it.

You are talking spring to knuckle clearance, right? Am I missing something here?

I agree with Jake. Your set-up must be different than my '88 as well.

Is everyone here turning that nut in the same direction to lower the car? I'm not so sure.


PS: Chuck - your hand looks too clean to have done any real work when that photo was taken!

To lower the rear you turn the nut counter-clockwise (to the left), as if you're taking the nut off the bolt. Down, down, down toward the floor/ground.

As you back off on the nut, the spring follows, lowering the rear.

Default spring clearance

It just hit me.

The new spring has a square end, the original is angled at the ends.

The part that actually makes contact is a corner of the spring.
