The only other thing I could think of would be to raise the chassis mounts up.

there are adjustable leaf spring shackles
for the rear mount point. they look like the stock ones, except they are longer and have
multiple holes.

if you cannot relocate front or rear mount
points or your rules do not allow the use
of lowering blocks, do this. get an old
leaf. cut it into 4-5 inch sections, as
many pieces as you need. torch cut a hole
in the center of each section. get a longer
bolt - the bolt that holds the leafs
together - and attach the sections to the bottom of the leaf spring.

techinally they are not lower blocks, just
very small leafs.

another thing you can do is get another
bottom base plate - the plate that
mounts under the leafs which also has
the lower shock mount hole. cut the shock mount hole arm off. add the plate on top of the leafs, such that you have plate, leafs,
then the plate with the lower shock mount point.

First of all: How much do you want to lower the car? Lay the spring flat and stick you a straight edge along the eyes and measure the arch. If it is a stock camaro leaf spring they usually have about 7 inches of arch. This is measured by using a ruler at the center pin location and measure from the main leaf out to the line you have made with the straight edge. Lowering the car will be directly related to this measurement. Take the spring apart and then using the same measuring technique measure the arch with just the main leaf. It is normally 1" or so less than the total spring pack. Get you 4 by 4 pieces and lay them 8 inches apart. turn the bow down and with a 5 or 8 pound hammer use the corner *don't hit flat down* just an angled blow at the center location between the 4 by 4's. Do this evenly, moving the leaf along back and for between the eyes. If you want to lower the car two inches then just take out 2 inches of arch. Continue with the leaves underneath being careful to match them up evenly down through the pack. stick your center pin in and clamp them together, measure your arch again to see how much you dropped it. Remember if you started with 7 or so you will need 5 inches to lower your car 2 inches. If you have the rubber pads in there throw them away and weld you in a center pin locator hole. If you don't have access to a welder then use the rubber pads!
If you want to lower the car more than 3 to 3.5 inches you have to move your rear hanger location backwards. remember the spring gets longer as the arch comes out. Hope this may help you. Arching is nothing.........I've arched thousands with a 5 pound hammer and an anvil. I was 12 years old doing this so I would say you have what it takes to tackle this job. MY2
