Thread: koni vs. bilsteins

Hi Tombraider,

Umm, I haven't faded any LTR's, never run them. (although I'm quite prepared to test some out )
I actually said that using a remote can/floating piston on a twin tube shock was how they would match a mono-tube in (fade free) performance. :wink:

For those that asked about increasing/changing the nitrogen pressure in LTR's, all it does is increase their fade resistance slightly, and increases the ride height marginally ('lifting' force is a function of the cross sectional area of the piston rod x the gas pressure. eg. 5/8 piston rod multiplied by 80psi = 24.5lb, by 100 psi = 30lb) this force isn't equivalent to or add to your spring rate, more like a light pre-load, known as a 'nose force' on the shock. This increase in 'nose force' used to be a concern to race car engineers using nil droop suspensions (spring and damper can't extend) It decreased the dampers sensitivity as it was an extra force to overcome to get the damper moving. In fact, it can be argued, and shown in a simple calculation that this doesn't happen with suspension droop, that the ride height increases slightly, and that the increase in nose force is cancelled out.

Changing the nitrogen pressure has no effect at all on the shocks valving.
