I have searched but need more specific info. I put Hotchkis 1 inch lowering springs front and rear. I need another inch maybe 2 for the rear and 2 or 3 inches in the front. What is the best way for doing this? I have read too many nightmare drop spindle problems.

as noted hotckis spring will only lower your car about 1" but coil overs would be the easiest way to get you car as low as you need. or you can go the old fashion route and cut the coils but you will loose handling.

In my 72 I have Year one drop coils in back with Hotchkis rear Susp. and Fat Man 2" drop spindles in front. It looks great but is very low (some times it's too low).

If you would like PM me your e-mail and I can send you a few pics:thumbsup:

I think the Eiback pro kit works great. Check my sig.

cheapest way is cut the coils just do a little at a time.

So what are the cons to cutting coils?

a weaker spring


Actually, the spring rate increases when you cut the coils as the number of active coils decreases. The spring doesn't get weaker, it becomes stiffer. There is no real drawback to cutting coils other than no longer accurately knowing the new spring rate short of testing them. Cut a little at a time, evenly, and DON'T put any heat into the springs. Just realize they will be stiffer than when they started.

As far as the rear, you can cut also but when you slice the upper "flattened" area off the spring no longer wants to sit correctly in the frame and they tend to move around. Your best bet is to buy some 11" single-pigtail circle track springs (which will get your car pretty darn low, it will nearly touch the factory bumpstops on the axle) and then fab spacers if you want it a little higher.

I have a spacer set up that bolts to the rear axle, it will raise it if necessary. Thanks for the input!
