Spring rate and length questions
Posted: July 9th, 2009, 11:06 am
Hi,
Currently I have 6" 2.25ID 700lb/in springs on the rear with a 2:1 ratio but want to experiment a little without it costing the earth, has anyone had experience with different spring manufacturers (are there any to avoid?)
I have a couple of other questions (Appologies if they are basic, elemetry questions but I am very new to suspension setup/tuning)
1) At what point when increasing the spring rate should you change the bump:rebound ratio and how do you work out what it should be?
2) at what point would you use a shorter spring with 2ndary "helper" springs?
3) does a 25lb rate change effect the handling substantally?
My current dampeners are single adjustable but I am unsure of the valving ratio (I will have to try and find the dyno plot for them). Initially I am looking for a "fast road" setup, but next year I would be looking to purchase another set of dampeners and springs (plus slicks) for track/sprint use as the Shelsley only qualifies in the "sports libre" class
Thanks
Chris
