Rep Power: 388 Spring Rates
Is there a way to tell what the spring rates are on lowering springs/coilovers. Most manufacturers don't mention it on their site. I know JIC can have custom spring rates or even ones that you can change the spring rate yourself. Thanks.

Rep Power: 356 you can have them tested. Problem is, I dont know where. Many co's dont list spring rates because the average person who Purchases Sport/Lowering springs wouldn't know what do do with the Information. The more Reputible Racing suspension companys like H&R, Tein, Eibac, and Neuspeed to name a couple, would be more then happy to tell you the their spring rates, all you have to do is call them and ask.

We under stand LBS/In her in America. Metric tends to confuse us.
157lbs/in front and 291lbs/in on the back. not very stiff at all.
The SS springs are
336lbs/in front and 448 lbs/in back. More then twice as stiff on the front.

Rep Power: 356 when Racing is involved Linear springs are better to have then Progressive ones. on the street, Progressive will give you a better ride when your just cruzin but still retain some level of performance when pushed.

Rep Power: 388 That is why companies like eibach, progress, neuspeed, etc say it is x-x% stiffer than stock. They vary when they are compressed/extended.

Rep Power: 356 One of my friends estimated the rate of his springs by measuing the Diamiter of the coil, Simmilar to how you can calculate the rate of an anti-roll bar by knowing its thickness.
I'll ask him about it.

Rep Power: 388 most true coilovers are linear springs, most aftermarket springs are progressive. Sleeves are just aftermarket springs on an adjuster so they are usually progressive too. But flotsamm is right.
