Cut springs vs. Lowering springs

[tunerdude]

I have a cut set of springs on my 67 camaro now. They are cut 2 inches. However, I have a brand new set of 2 inch drop springs in the box. Should I keep the springs that I have on the car since I know that it really is a true 2 inch drop, or try the lowering springs? I do believe they are the original springs that ore cut and on there now. I am also going to mount Edelbrock IAS shocks up to these.

Second question. I have a mono-leaf rear, should I upgrade to the 3 leaf multi rear or dearch my monoleaf. I want about 1.5 to 2 inch drop in the back as well. If I dearch, should I upgrade to a multileaf rear and then dearch or stay with my monoleaf rear and dearch. Or will dearching multileafs be a waste of time and defeating the whole purpose of multileafs. Will the 3 leaf rear give a lowering stance by itself without dearching?

I am running 17 inch rims all around with a 350 in it.

Thanks for the info.

Factory springs were designed to work at normal ride height, and with a 6" wide non-radial tire, if you lower the car you reduce suspension travel, you need to stiffen the spring rate to compensate for the loss of travel or you will be riding on the bumpstops half the time.

The mono-leaf spring is the same deal only the mono is REALLY soft!

Does shortening a coil spring make it slightly stiffer?

I'd recommend going with a purpose built spring. Or atleast get a newer spring and cut to fit like suggested on Pozzi's site.

I will have to check my records as to what springs I used on the front, but the stance can be seen here....
