(You Must Read) Fixed Rate or Variable Rate Springs
Here's a quote from the new May edition Chevy High Performance Magazine:
Quote: Very few race cars run variable-rate springs yet marketing efforts have convinced the public that they are a superior overall setup. "A properly tuned linear-rate spring with properly valved shocks can ride and handle better than a variable-rate spring," says Kyle. "A strait-rate spring is consistant thrughout the vehicle's suspension travel. With a variable-rate spring, the shock valving must account for wide range of spring rate, which yields compromised ride quality and handling performance. Un quote.
Here's a spring chart listing what is fixed rate and variable rate. http://www.angelfire.com/my/fastcar/suspension.html
By the way, Sam Strano's custom springs are not listed here but his front springs are a fixed rate spring. I just wish he would release a taller spring kit that would give use street Fbody guys more clearence for headers, curbs, rough roads, etc...3/4" drop would be perfect Sam

Maybe you need better fitting headers?
My springs are what they are not because it looks good, but because I feel it's the best height for performance. Low enough for a tangible drop in center of gravity, not so low to leave you with messed up geometry and no travel.

I'm not going to make 3/4" drop springs. Not enough market, and there are two other ways to get that drop. SLP springs, which I also sell. Or stock springs using Koni's on the lower perch.
I can help, I do sell other products too.

Whatever you say my friend. My point was simply if you want to drop 3/4" I don't need to make you springs to do that, and I didn't make my springs 1.25" because nobody else did. I did it for performance, that what the springs are about.
Again, I'm offering my help in figuring out a plan for you. But we need not get into a bickering session about the springs. 3/4" isn't a huge market, it's a compromise, and there are already compromise things available.

i used to always think that 3/4" would be perfect, but then realized with something set up properly, I can get away with something like your springs and not worry about much.

I can see it now...this would be cool
Strano Level 1 street kit: .750" drop linear springs and matching shocks
Strano Level 2 road race kit: 1.3" drop linear springs and matching shocks
My car on left with stock springs. Someone elses with PROLINES on right. I need something in between...3/4" drop would be perfect.
RED Camaros have a higher resale value

Ok, did you actually measure that car on the right, or are you assuming it's 1.2" drop because that's the claim Eibach makes? Eibach's tend to drop more than the claim more often that not. And let me try this one more time.
WE CAN LOWER THE CAR 3/4" IF THAT'S WHAT YOU WISH TO DO, EITHER BY SLP SPRINGS, OR WITH STOCK SPRING AND THE LOWER PERCH OF THE KONI'S. Further, you could buy coil-overs and do it that way too. Again, willing to help, and I appreciate the fact you trust me enough to want me to make springs for the job. It's just that I think we have other workable options here. Which I'd pick depends on what a conversation between us tells me.

So a 3/4" drop is not possible? OK..I will have to use SLP's 3/4" drop variable rate spring kit.

You can name them Gollum Springs, or "the Precious"

Anyway...fixed rate springs are easier to dampen than variable rate springs.
