Questions about going with 1" drop springs
 
I have been upgrading the rear suspension on my 68 Chevelle to include 12 bolt posi, upper and lower control arms, Lakewood shocks, control arm braces, sway bar, drag bags, and MT street radials. Now I am thinking of upgrading the coil springs and going with a set of 1" drop springs.

Can anyone tell me if this will cause any unforeseen problems, especially if I convert the front end to 1" drop springs as well. Are there any other issues with the front end alignment that I will create by dropping the front end by 1"?

Are there any particular brands of after market coil springs that I should consider?

Thanks

The Chevelle is 40 years old ... and most likely ... the original springs have already " LOWERED " themselves a inch ... maybe more. I have a friend who bought some 2 inch lowering springs and he got about 1/2 to 3/4 of a inch results ... because the springs on his 66 SS Chevelle had settled a decent amount over the years.

That is why you should always change springs in pairs :D

I see no real issues lowering the car a inch or two. Any more and you can run into driveshaft interference with the bottom of the car. :(

dropping an inch or so?
 
Deuce had good comments for you. You've got to keep in mind the age of the current springs AND whatever changes you have already made (suspension and all) and then realize that there is no way to answer your question for sure. You MUST take a good look and see what another inch or so would do to driveshaft clearance (as Deuce mentioned) and tire clearance (at the fender and inside the well). Also, how hard are you going to be driving your beastie? Hard high-horsepower launches will require more space for movement than the average street dirving. Just drop a few sandbags into the trunk until the bumper drops 1," take a good look at clearances and then guess how much more space you would still need under the pressures of your driving style.
Good luck.

Thanks for your comments.

It seems that just some good common sense and vehicle use may be the determining factors.

Looks like it got a pretty good stance to it right now.

The stance looks really good...I wouldnt mess with it unless your looking to improve the handling and and how the car rides. As old as the car is the springs have settled a lot. One thing you run into using drop springs is that you will reduced your suspension travel. New springs will definatly stiffen the ride compared to the old springs and bring the car back up a bit maybe. I lowered a 1990 GMC pickup and used 2" lowering springs in the front. Man did I regret doing that. The handling and suspension travel were crap. The next truck I did I used drop spindles which keeps the amount of travel the same...just lowers the vehicle. Just remember...align the car after you make any changes. Good luck!!

That's just the thing..........the stance is great right now, but I was thinking of replacing the springs since I currently have the rear end disassembled, and I am getting ready to tear out the front end and upgrade all the bushing, ball joints, etc. I would hate to change the stance, especially if a 1" drop spring actually raised the car. Since I don't know how much the original springs have sagged, even the 1" drop spring could give me results that I don't want.

Maybe I need to reconsider and put this money elsewhere. Thanks for the feedback.
