Post your verified spring rates here

[cburkart]

You know, I've been thinking about why some of these companies refuse to publish spring rates. Could it be that their quality control is so poor that they're afraid of someone actually measuring their springs and finding out how far they are from the specified rates?

I really can't think of any other explanation; as stated before, if a competitor wanted their rates, they could quickly and easily buy a set of springs and get them measured.

I know my H&R rates for my MK3.

800lb fr
515lb rr

Oh yeah these are Group "G" race springs.

[Martinus]

What ??? 800# front springs ?

Can anyone post rates for Shine's Mk3 VR6 GTi rates? I've only seen Mk4/2 rates, no Mk3 support.

300 front

I think someone should put all the rates together and then ask the moderator to make it as a sticky on top. This would be a very needed thread.

sorry for pointing out the obvious!!! I'll try harder NOT to help in the future

[f1forkvr6]

You know, I did a quick check and there really aren't many posts about MK II spring rates (other than Shine, other than someone using MKIII VR6 Shine springs on his MKII, and a post about skunk 2s with rates that are much too high for a daily driver). Mostly MKIII and MKIV stuff (and my B4 info )

Which MKII rates have I missed?

Thanks, I'd like to know about neuspeeds, h&rs, and eibachs mostly. Any others would be helpfull.
You just can't stop can you wolf.

Sorry to bring this back from the dead, but I now have verified spring rates for the Autotech Clubsport (1.8T and 2.0L). These are progressive springs custom made for this application, you cannot buy them alone. Looking at the working rates there is a striking simialrity to the Shine setup (Dick will probably flip that I dare compare his linears to some progressive spring, but too bad!).

FT initial rate: 120lb/in
FT final rate: 265lb/in
FT working rate: 200-250lb/in

RR initial rate: 100lb/in
RR final rate: 180lb/in
RR working rate: ~150-180lb/in

[SRSVW]

Einsig if you put these springs in a tester and measure them at the installed lengths you will be shocked at what you find! They are linear!

I just bought 337 suspension set and am curious about how good they are.

The reason I did not post that picture myself is because the spring tester may not be accurate, which makes this result "not verified", therefore does not belong to this topic. Once the spring is tested again by a different tester, a more modern and accurate one, then it will be safe to post it.....

What would be a good spring to match up w/ bilstein sports on a MK3 GTI VR6

I know lowing the car too much will not give optimal performace, but i'm not racing or auto xing....just having fun driving on Long Island roads...looking to lower 1.5-2 front and rear matched w/ a rear sway bar...

so what would be good springs to do this...and what would the rates be?

[GTI.TECHNIK]

Bilstein Pss9 spring rates are 400fr. / 315rr. ... I just wanted to clarify that cause someone had put the wrong spring rates for the pss9's earlier...

I verified with Eibach on two separate occasions regarding the spring rate… It is 131lbs. What makes the car not bottom out is the fact that it is linear rate. I know when I had the H&R sports on the car, it was lower although the springs are technical stiffer. Also, the bump stop acts as a secondary spring to prevent the suspension from bottoming out. I have an Autotech lower tie-bar and I haven’t had any clearance problems with the Pro-System.

Not to dig up a dead horse...I thought the very definition of bottoming out was when you hit the bump-stops.

[JeffMk4]

can someone please explain in detail what spring rate is????

[f1forkvr6]

You'll find an explanation on the first page Here

Many companies don't publish the rates because typical street application type people don't need the information, and don't know what the information means.

Many people will simply look for the spring with the highest rates and buy those. Obviously any spring can easily be measured for spring rate, so there's no hiding the facts, but some companies cater their springs differently, and it isn't always the rate that's most important.

warning ... [rant=on]
But - should a potential customer request this information, it would be much better from a customer relationship standpoint to release this information. Why take a hard stand against releasing spring rates, when as you've stated, they can be easily measured? I'm sure it's policy, and has nothing to do with quality control, but it seems to be a pretty silly policy. Folks who could care less about the spring rate won't ask, and others who want to make an informed decision, and are capable of doing so, should have unfettered access to the details about the product they are about to buy. [/rant]

Potential story ...... A guy just tested his Stock front Golf springs and the result was about 150 lb spring rate. Then he wants to enhance the handling of his car, by lowering it and stiffening it. He reads that a company called H&R sells their "Sport" springs. He reads on the website that their "Sport" springs are xx % stiffer than Stock and about 1.5" lower than stock, this way to stiffen the ride and lower the center of gravity, so it is all win-win situation ...... so, he calls them and asks about the springs rates, just for curiosity, as he already knows his Golf's stock values to be 150 ....... the answer he gets is: 130 lb/in Front and 137 lb/in Rear! .....

So, I guess it will be very difficult for the rep. to explain how exactly the new, enhancing-handling, stiffening-the-ride "Sport" spring is actually softer than the one it replaces..... Yeah, the guy does not really understand much about spring rate values, but he would surely know that 130 is less than 150......

At that particular point the rep. has to explain that it is all good, because those "Sport" springs have to be installed with those "Sport" dampers, which have very stiff bump stops, and because the spring is too short, the car sits nicely on the buffers, which do add a lot of spring rate, so TOGETHER with the low rate "Sport" spring, now we sure have higher than stock spring rates, so "stiffer" ride is now understandable....... But try telling that to a potential customer and see how many would gladly accept the news that they have to ride on their buffers all the time as to get the "enhanced" handling.

I agree wholeheartedly.

Well, I think LOTS of people will ask just for the sake of asking, then have no basis with which to compare to. For example, people are always asking what xyz spring's rates are, without even knowing what they're got on the car to begin with. At that point, the spring rate isn't very useful.

In any case, most professionals serious about racing and performance run a standard size, 2.5", 60mm, or whatnot, which becomes a moot point, as all those rates are typically released.

[hayden]

Looks like these have come to the market. Not exactly verified, as the info is just from their site. Nice to have more options though.

Manufacturer: Tein (S.tech lowering spring)
Vehicle: MKIV Golf 4-cylinder and VR6 models
Lowering F/R: 1.5"/1.6"
FT Rate: 196
RR Rate: 179

[f1forkvr6]

Those rates seem a bit low for that amout of drop.

[SlvrBllt]

I thought the Eibachs were supposed to be progressive rate?

[fritzner]

is anyone planning on putting this great information all together in one table or something??...

great work everyone..

[abog24]

so what is the stiffest (or one of the stiffer) springs that lower the car at least 1.5, 1.6 or 1.75 from stock ride height? THanks
