I've got some tokico illumina 5 way adjustable struts on an LS Integra. We can't figure out where the stiffest and softest settings are because the little adjustment piece spins full circles and doesn't stop. Has anyone ever used these/have these? Would be a great help, Thanks.

 

I have them. 5 is firm, 1 is soft. I'm running 5 in the front, 2 in the rear. Personally I wouldn't buy used illuminas as I think they wear out fast. I started with a 4 in the front and after about 2 months the 5 setting was about as firm as a 3. Oh well, maybe yours will be fine.
