H&R spring rates?

Unique_Z · 10-04-2012, 01:19 AM

Hello guys, i'm going for a BC-Racing coils with custom spring rates, with that said i'd love to run the same rate as my H&R lowered springs. Thus, does anyone knows what is the spring rates for H&R? and yeap i've done my research and couldn't find anything except for the lowered height details.

Thanks in advance!

This is not published information. Even if you call H&R.

You can have it measured, with proper equipment.

Call up a university near you, just a hint

http://www.engineersedge.com/spring_tension_calc_k.htm gives you a pretty good, rough estimate, but to be more exact you'd need material sample for density (if they use compound alloy it will reduce the error if you know it).
