    I am sure it has been covered before but cant find anything. What is the best way to drop it down 3-4 inches. its got the coils on on all 4 corners. do i cut em buy the jamcos or is there another coil that will work. if you got pics with what youve done post em pleases. also how low can i go with out messing up my driveline as it is the closed style with the 3 speed.

    Cut the fronts just slightly......78 el camino rear springs. Should get your car pretty low. Don't cut too much from the front. A little goes a long way. Good luck.

    Remember each inch cut at the spring = 1 1/2 or so at the fender plus makes the spring ~10 pct stiffer.

    Ok I took the Chevrolet Springs and added 600 pounds front end weight.
    The stock BOP spring ride height in that era was 10.375. I uprated the springs for the Buick weight and I see a couple that should be close. If you took the springs out and measured the height, diameter of the wire and the number of coils I cold give you something pretty exact.

    Styleliner I'll work up something for you too.

    Styleline, here are some springs to check out, I used the 50 Chev standard spring, they had more detailed spec than 49.

    The spring info is from Moog. I took that and then estimated what the weight would be in your front end and then calculated the load that way.

    Most people think the BOP cars work best around 9.5 loaded spring length. Take it easy and go mild if you want to avoid issues.

    Once you measure your springs we can be more accurate.

    I bought the Jamco 2" lowered springs for the front of my 52 Super. Looks good and rides great. Still trying to figure out something for the back...

    Remove your rear springs and block the frame at the height you want. Then check the ball socket on back of Trans for adequate room to move with susp travel then look for rear springs or cut I would be conservative at first. Too drastic a change can take all the fun out of yer ol Buick just my .02
     
  19. Contact Yaril. He can tell you how low you can go without a drive line problem. Here's the contact info. He's also on here but you'll get a quicker response this way. The link also includes a phone number if you want an answer really fast. He's got a Buick that ran a static drop before he bagged it. He had it pretty low before the bags.

    51 Special,
    This is the way to go, I did this same thing on my 50 Super and it worked out great. I have yet to cut the fronts, but that is next, running as a slight tail dragger right now with now problems with the driveline. The 78 El-Camino springs jump right in like they belong!
