Default (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.

All current long tube headers will drag when lowered more than stock.

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

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.

BULL... me and others would buy. I read post all the time about Proline and other springs being TOO low for the rough streets.

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.

which is why SLP makes them to begin with


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 lowering my car 3/4" using the stock linear OEM springs is a wiser decision than going to a custom higher linear rate Strano 3/4" drop spring. I really like the fact that your springs are lighter than most all springs.

SLP's hang down further than most LT's I've seen. I ran Jethot's with a quality road race spring and never drug mine. I think it's a known fact the SLP's hang low. Just my .02.

I have Kooks longtubes and catted ypipe, with Strano springs and I'm not close to having them drag. Your SLP headers are probably the worst headers out there for ground clearance on fbodies. Hell you could even put sportlines on and not have clearance trouble with Kooks

its a well known fact that slp lts hang low. coil overs would be the way to go but not every when is rich. Or bags but those are expensive too.

Why are you telling him? You should keep that secret and make your own street kit. You can make the profit. Hell if they are a good rate, I'll buy a set someday if I get a street camaro again

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

That's the first time I've ever heard that to tell you the truth...it sat higher than every Pro-kitted car I used to be around in the Panama City/Ft. Walton Beach area.

BULLSHIT! All 4 into 1 long tube headers WILL drag especially over speed bumps lowered or not lowered.

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