34 way damper adjustment, full independent height adjustment (doesnt affect spring rate).
weight only about 4.5kg each as they are alloy. this is pretty good considering the stock struts weight about 11kg each, 26kg saved
very good for street/track, not too uncomfortable but still handle very well.

these have done a max of about 10-15kms, a year or so old
