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......


TIA

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.

Welcome to the Team!

I might add that when I installed two inch drop springs on my Impala with over 330,000 miles on the clock it rose an inch higher that it was with the worn out springs.

I have a 66 Impala SS 2 door

I used global west (S-87) front springs for a BB and stock springs on the rear with Aftermarket ebay front tube arms
(with ball joints replaced with MOOG K6035 and MOOG K6034)

and bilstein shocks on all 4.

Also used C3 corvette Spindles in the front for brakes but I don't think they lower at all.

I have 15x8 steel wheels with 4.5" bs and a 245/60r15 tire on all 4.

My car sits pretty level not too low but I would guess lower than stock.

I am running a Big block Chevy motor.

Here are some pictures:

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.
