Strano Springs--IN STOCK (for now)
All backorders have been filled, and we have springs available for sale on our website: www.stranoparts.com
Just click on you make and model car, go to the "suspension" section, and the springs are part number SP141 listed under Stranoparts.
Price is still $275 shipped to the continential US (not sure for how much longer given the price of moving these things around)....
Approximately half of the 100 sets we got have been shipped, leaving around 50 sets available currently. Many of you know the details, but for those that don't:
-550 lb/in front, 150 lb/in rear springs. Linear rate front, linear working rate rear because actively progressive rate springs are not able to be damped properly due to the variation in rate. You will not find progressive rate springs on serious performance cars, and never on race cars.
-Approximate lowering 1.2" (variable due to your car's original height).
-Both the spring rates and ride heights were specified using information directly from the spring rate and ride height I use on my own car.
-The Springs are made from VVS alloy that is 35% lighther than the Chrome-Silicon most springs are made with. A set of our springs are on average 13 pounds lighter on our ship scales than common lowering springs from Eibach and Hotchkis.
-While designed for handling above all, they are among the best launching lowering springs due to the fact we don't use extreme rear rates, or slam the ride height, both of which hurt weight transfer. 150 pounds is actually the average of the rates used by 1LE springs. Our rear springs are 25% stiffer than stock, but are also as much 12-30% softer than other lowering springs.
-Why are the rear springs not brutally stiff? Simply put they don't need to be, the rear suspension is not complex and is very similar to a pick-up truck. Like a truck, if you over spring it for the amount of weight you carry you simply cause the rear to loose mechancial grip. It will skip around more and just not let the tires stayed glued to the road as well. Also you hurt the cars ability to squat, which can and does help traction.
-Why not use stock rate rear springs if softer is better? Like anything you have to assess the total situation. If we didn't stiffen the rear springs at all, the car would be very sluggish responding in the back and not very well balanced.
-Are the springs streetable? Very much so. I'm a believer in the addage that you use as only as much spring as you need to get the job done, and no more. Anything more costs mechanical grip and ride quality unecessarily. While the springs are firm, when teamed with good quality dampers (shocks) the ride is considered by most to be much better than stock because the harshness is greatly reduced vs. stock despite the higher spring rates.
-Cost: $275 shipped to the continential US.
We realized our springs are not the cheapest out there. And that's because we don't use cheap materials. And if you consider the total costs after shipping I think you'll find the price more than fair for what you get.
Here are some pics of the springs on various cars (and thanks to those that posted these).

I am seriously considering these in place of my ProKit.
But I love my current stance. I have seen cars on your springs, and they look like they are maybe 1/4" higher. Sound right??
Are they any softer than the ProKit? I assume they would probably allow for slightly better launches as well.

Pro-kits vary so much that I can't tell you exactly how we'd compare. Some sit very much the same as mine, some sit way lower....
I can tell you that on stock OD sized tires, that most LS1's sit about 26" front, 26.5-26.75" rear when you measure from the ground to the top of fender/quarter panel opening. Most every car drops 1-1.2 in front, and right about 1.2" in the back vs. their stock height.
My springs are not softer, in fact they are 150 lbs/in firmer (550) in front, and my rears work @ 150 rate vs. 137 for the LS1 Pro-kit rears. And to a person folks feel they ride better. Simply put the LS1 Prokit is too low for the rates being used. When you get to the bumpstops (and you do, with mine as well), you hit them harder, faster and more often than with our springs. We still use them, and shocks are still a huge key in any good suspension, but in this last run I've had two folks put them on with stock shocks (not my choice) and both reported they car rides no worse than stock springs/shocks did.

It sounds like height wouldn't be a problem.
But since the ProKit is too low for the spring rates, would the stiffer but proper height Strano spring improve my launches, or make them worse?
It is a street car first and foremost, but I do like it to perform well at the strip as well when I do race it.
Koni 4/3's are the shocks by the way.
Thanks!! Really leaning towards picking these up while you have them.

this is probably my next purchase! you may mention that the pro kit is about the same price (sometimes more) so you might as well get the best springs . . . strano!!

Lowering the car hurts weight transfer. We aren't as low. We also stay a little more off the rear stops and you can hit those if you launch hard. The rear rate of 150 is not super stiff (purposely) so that won't hurt you.
I have guys with handling packs on cars (these springs and Koni's) that can cut 1.6's all day long without being "drag" cars. Could well be someone cutting even better times on the springs, I don't know as that's not what I meant them to do. But in the end I don't see the springs leaving any worse, and I suspect slightly better--but can't prove it.

When these are gone... they'll be gone for about 3-4 months (that's how long it takes to get more built and shipped).

The site does not take PP. However, if you would like to place the order via the site, and then just send the money via PP to my e-mail address we can handle it that way.

Last time around it took 18 days to sell 65 sets.... I can't know until they are gone, but they tend to evaporate.

Being that I'm closed tomorrow and probably most of Monday that shouldn't be an issue... unless I get flooded with online orders while I'm gone.
Closed because I'm off to a National event this weekend in New England.

My life is a- Ben Stiller movie.
what do the pounds associate with springs mean? and while you're at it...what's the difference between "progressive spring rate" and "linear" ?
