Thanks for all your help people, I know it's a four-door, but I am considering lowering her a little now, some suggest cutting a coil off each corner, some say that spring clamps are also available, what's the best way to go? http://youtu.be/eaWnh44NRdU
Pretty sure GM did away with all kingpins (except trucks) by '59. The best, cheapest way to lower that '60 would be cut coils. If it were mine, that's what I'd do... at least at first. The rears have a pigtail on the axle side of the spring which holds it in place, so be sure you cut from the top/frame side of the coil. Start out with one full coil and increase from there to suit your taste. I think I took 2 full coils out of the front & rear of this '59 Cad and I like where it sits. 50's low not 90's low. Once the bumpers & interior go back in/on, it'll probably drop another 1/2" or so...Pretty sure it has the exact same suspension as your Buick
so then would it be safe to cut one coil off each of the rear springs? (I don't want to mess with the front springs..) https://www.facebook.com/photo.php?...01237739559.2186977.1556405416&type=1&theater
59 Cadillacs have a driveshaft with a carrier bearing (center support bearing). 60 Buick still has a torque tube, right? It wasn't till 61 that they were open drive? I remember a 60 Buick that kept having transmission leaks from the rear because it was lowered a lot and stressed the seal at that union. My memory is pretty fuzzy on it, it could have been an air-ride specific issue. Doesn't sound like you're lowering it much and just in the rear, maybe just keep an eye on it. Sorry I don't have very clear info here. I just thought I'd mention it and maybe someone else will jump in that's more familiar with this than me.
Just noticed that the original post was from a couple months ago. Did you cut the coils? How did it turn out? Great looking car by the way!
Thanks JohnJoyo planning on cutting them next week and then let you know.. I'm too conservative to cut more than one coil..
Cool more door, I'm cutting coils in my more door '61 olds next week, yep starting at a 1 ring first as well. Are you after a level ride or a tail dragger?
I've had cars with the same stance as yours and just lowered the back a hair lower than the front and left the front alone. Put some kind of weight in the trunk to see if you like that
i heated mine, more the rear than the front. then put new shocks on all 4 to be the right size. it rides just like factory believe it or not. ive put 100s of mile on it so far and love the ride quality...
Fatman Fabrications makes a 2" inch drop spindle for the front that allows you to use the regular brakes or disc brakes from a C-10 truck - http://www.fatmanfabrications.co/make/buick/1958-1960-buick-dropped-spindles/
