View Full Version : spring values of aftermarket anti roll bars for 2 E30?

08-03-2011, 10:06 PM
Does anyone know of the spring rates for the front and rear anti roll bars made by eibach or suspension techniques? Or would you have one and the means of measuring it?... Fix the one wheel, put a scale under a jack and jack the opposite sides wheel... Somethin along those lines...

As I am broke, and still in school, I figured I could make one for cheap, just need to know the 'k' value

search it up. E30tech has the diameter in it.

Thise are just sizes though, to get the spring rate from that I would need the material, and wall thickness as well...:(

I can get 1' tubing, just need a wall thickness, I'm sure its gotta be a standard value, just need some help with what it is, also I presume mild steel?
