Default New suspension not so good????

Got the new suspension front and rear installed, and it looks like a "Bubba" ride (OK for my 4x4, but not the 1980 Vette...sitting about 1 1/2 inches too high;
The rear has adjustable end links, but not sure how to lower the front.
(cut the springs down?).
I put 255-60-15 tires on. The new front springs are actually shorter than the old ones by an inch.
The ride hieght just looks too tall for my taste.
Anybody know how to get this thing down closer to the ground by at least an inch or more?

Have you driven it and let it settle?
What springs are on the front? 460s? Some people cut an inch off those to get them to a more desirable height. 550s tend to give a nice lowered stance.

On the back, you need to get a 10inch bolt, and just don't put tighten the bolt all the way up. You can get a grade 8 bolt for it at any industrial supply house, and get nyloc nuts for them.

The front cut a half coil off at a time until you get your desired ride height.

Have not driven it except to move it...how much could be expected from a weeks worth of driving?
I've still got about 1 1/2 inches left on the rear end link on the spring;
But looks like the front may need cutting.
Not sure what the rating is on the front springs, but the whole thing was a kit. Also the rear sway bar would not fit between the wheels.

Did you wait to tighten the bushings until AFTER it was sitting on the ground?

Did you torque the control arm bushing bolts before putting weight on the front end?

Can this be done or redone after the fact?

You let a complete stranger work on your Vette ? Or was it a shop with national TV & radio ads?

Loosen the control arm bushing bolts, drive the sucker around and see if it settles. If it does, do not let that mechanic ever see your car again.

Re-torque when done.

Not complete strangers...they have been in the area for over 25 years and have a very good rep; the owner drives and has owned several Vettes over the years, and is currently into T-bucket hot rods.
Thanks for the input, I'll give it a try.

Also make sure that the front springs are seated in the lower a-arm pocket correctly. If not that will make your car ride high up front. What type of rear spring did you get? Did they run the bolts all the way up? If so back them off and the car will drop.

All aftermarket spring are shorter than stock so don't worry about that. The coils are wound tighter than the originals.

I got the "performance spings" from mid-america. I can see that backing off the locking nut on the rear will lower it enough, but it's the front I'm worried about. I don't know if the old stock springs in front are actually bad. How obvious is the incorrect seating of the front spring into the lower part of the arm-pocket?

1. The upper spring must be seated in the upper pocket(in the groove). Bottom doesn't matter.

2. Don't torque the CA bushing bolts until there is weight on the front end.

By you mentioning that it sits like a 4x4 is a good indication that the front spring may not be seated correctly. If you look at the lower a-arm while it's on the car the ball joint will be toward you. In the lower a-arm pocket, there is a dip in the pocket. That dip will be directly behind the ball joint(in the pocket. The end of your coil spring MUST be in that dip. If it isn't, thats the reason it is sitting high. Your probably going to have to take the front wheels off and turn you steering wheel all the way to one side and get in there with a pipe wrench. Put the pipe wrench on the coil spring and turn it until it is seated in that dip. A couple hard jerks should get it over.

BTW, coil springs generally don't fatigue. Leaf springs do, though.

Seems like some are saying that the spring has to positioned in the upper pocket and someone mentions the lower pocket. Lars mentions in his write up to install the spring so the end of the coil come right up against the water drain hole in the lower spring pocket.

So from reading all the info in this thread and in other threads, the spring has to positioned properly in both pockets and has to be checked so that it doesn't cover the drain hole. Correct??

Most of the newer spring are not cut like the old ones. I believe the original springs are cut 180 deg from one end to the other. The new ones are cut 90 deg from one end to the other. I don't know why this is but, it is more important to have the lower a-arm seated correctly. If the lower is not seated correctly than your car will sit high.

Let the car settle for 100 miles before final torque on CA bushings - this will reduce the chance of tearing the rubber.
