Nik Links Spring Rates

[Martin B]

Just wondered if anyone knew on here what the equivalent spring rates are for the soft, medium and hard Nik link bars for the front of a Clubsport/Prosport/PR6 are?

Thanks

I guess that is a no then!

Yes they should have, it is still a spring after all. The rocker ratio still needs to be accounted for to get the wheel rate though but that is the same for the main spring too (although different rocker ratios for ARB and main spring on Radicals).

I will have to measure the ones I have (only have medium and hard) just haven't got round to taking the one off the car yet.

Thanks for replying though Bert

I think the roll stiffness should be a combination of the main spring rate and the anti roll bar rate (ignoring roll centre influence here of course), so if I want to maintain the current roll stiffness but soften or harden the suspension for other reasons, knowing the roll bar rates will give an informed head start on the main spring rate revisions. Both main spring and roll bar rates need to be calculated to wheel rate to do this though.

I was also after the anti roll bar rates as I have a design in my head to do away with the bendy bar and replace it with coil springs with an additional element to provide the 'third' element which comes into play when aero loads increase as per proper race cars.
