stiffer than I currently have..

what you got that you've replaced.. wanting around 350 or harder

 

Give us a clue - what diameter and length and what do you have?

I've got a pair of 60N/mm (343lb) x 200mm x 60mm + 2x 50Nx250 + 2x 40Nx250 all 60mm id surplus atm.

 

got sum in the garage but i think there only 250 lbft

ill check later, got sum others that came with the coilovers from japan, not sure if theres markings on them but there rock hard

will see whats up with them and see if there marked

 

Duncan, I dont know, they are to fit an Avo Kit
