[QUOTE="hadronuk, post: 101710, member: 1866"] At this point, I would greatly appreciate all views on spring rates for the a Girdraulic coilover and [B]also suitable preload.[/B] CAD design work is now in progress, and it seems the greatest problem is fitting the spring in the available space. It seems certain the spring will have to be specially made and will need to be high quality. A spring with a fitted length of only 6" that will be compressed by 3" + preload is going to be very highly stressed. So I would really like to get the specification as near right as possible first time, as several iterations will be prohibitively expensive for what is likely to be low volume sales. My initial suggestion is 150 lbs/inch, but there is time to change this. Above there are several discussions of spring rates without it being clear whether this applicable to the Girdraulic or Brampton forks. I am happy to be corrected, but with the differing geometries, I question how applicable Brampton rates are to Girdraulics? Thoughts appreciated. [/QUOTE]
