Hi.... I want to lower my 66 Chev. I'm thinking of cutting one coil in the back and drop spindles in the front.
With stock BB rear springs, anyone have and idea on how much it will drop....1/2" or 2"? I'm hoping for max 2" at the rear....
Anyone who has done it chime in just to give ma an idea......
2" in the rear will almost put you on the factory frame bumpers, if they are still there. I used a 1" heavy duty drop spring from Eaton Detroit Springs. There should not be a difference between rear BB and rear SB springs.
Front drop spindles do what they say but will put your control arms closer to the ground as well. I wasn't thrilled about it but does not seem to be a problem for most driving. If you are using old front springs, you may already be lower than factory height and find you have some clearance issues, especially if there are headers installed.
Honestly it's difficult to say how much it will drop because age plays a factor. (which Dave eluded to and it is common)
I know you don't want to hear that it's trial and error but it sucks when you cut too much from the get-go! If you are really aiming for 2" drop in the back, *on existing springs*, then I think you can safely cut 1 coil and see what it gives you. I would not start out at 1.5 or more coils for sure. too aggressive IMO.
FWIW - I bought my rear springs from Eaton Detroit Spring as well and the rear of my car sits really nice in the back. The fronts are a whole different story with Eaton.
