Martin, I did enquire with a couple of people.
Thing is the nuts, which hold the spring up (?!) were also corroded/rotten and actually came apart in my hands. So it would have been a lot of work to get them sorted.
I was also told by our resident suspension expert that they were probably bin fodder.
I still have them if anyone wants them ?
They are a bit of a mess (95k,10yrs).
I'm gonna chuck them soon, so let me know.
I'm well happy with the H&Rs though. I think the Teins (when new) are more suited to track driving (speculating).
btw. They are the Tein HRs which are not damping adjustable.
Cheers
