live axle and spring rates

[John Gaines]

I purchased a set of the Avo dampers that Len was selling around 10 years ago. Driving round the Sussex roads with poor surfaces the car can be quite uncomfortable at times. Would it be worth going for softer springs and if so what rates would you recomend?

I thought that the std spring rate was 100 or 110 lbs, here is a spring rate calculator to see what you have now http://www.thespringstore.com/spring-calculator/spring-rate-calculator.html

I run 350lb on the front, but I have widetrack, so this is reduced to more like 250lb I think, compared to standard track.

On the rear I run 110lb, but you might want ot have a read of this - I had Avo rears and found them far too stiff on the damping: http://www.our-nest.co.uk/Caterham/html_files/2008_ProTech.htm

The old standard rears were 90lb I believe, but I may be wrong. You should be able to grab hold of the rollbar and bounce the rear of the car quite a lot - if you can't then I would suspect the dampers (but worth removing a spring and having a measure & calculation).
