Progressive vs Linear Springs

I searched the forum, then googled this and read about them on numerous forums, but would like feedback from yaris drivers - Advantages/Disadvantages. Most posters on other forums said linear are better for track days/hard driving, and progressive are better for simple street driving. I know tanabe springs are linear, but what other brands of springs are linear and which are progressive? I'm assuming progress springs are progressive due to name/brand, lol.....?

I think progressive their spring rate progresses as they are further compressed which is typical of road dips taken at high speeds. So it gives you a near factory ride during round town driving and freeway speeds and hard corners gives you the benifits of a higher spring rate.

Linear spring rate never changes which is good for track but local town driving it will be a little unconfortable.

leaving the differences between one and the other on the side....

ALL the available bolt on springs for the Yaris are progressive.

If you want linear springs you will need coilovers or do some custom modifications to the suspension in order to be able to fit universal linear springs.

I googled, but can someone with more knowledge break down which springs are linear and which progressive? I know that the tanabe springs are linear and tein s.tech are progressive, but what about other brands such as progress, megan, etc?

I think so, but I've notice that more companies are popping up with progressive springs.

Most coilover setups use Linear. Most lowereing springs are progressive.
You can usually tell by the way they are shaped.

What shape determines what? Wouldn't most lowering springs *non coilovers* be linear since they post their rates, etc?

H&R are progressive springs. They don't publish spring rates.

.... as I already mentioned a few post above...



ALL, meaning ALL available replacement springs currently available for the Yaris are progressive.

The spring rates that the companies such as tanabe / tein publish are aproximates or average (not sure what method they use)


The lowering springs (Tanabe / Megan / Tein / H&R) are sporty springs... not really race springs. Threfore these need to maintain a decent level of confort. Hence these companies use a progressive design.


Coilovers on the other side use (must of them) linear springs as they have more agressive shocks.


My Tein Basic Coilovers uses a combined set up. Linear springs on the front and progresive on the front...
But then again, these are not race coilovers...

You can tell by the spacing and width of the spring. If the spacing and width are the same between every coil then it's most likely linear. If the spacing and width vary between coils then it's most likely progressive. Some coilovers have two linear springs of various spring rates. The soft spring rate spring is often a short spring, just a few centimeters tall usually.
