It's time to replace the strut/shocks on my 85 GLH.

I found Sachs Super Gas struts/shocks and KYB GR2 strut/shocks.

I don't have good experience with GR2 as they lasted a very short time on the Daytona and the current strut/shocks on the GLH is GR2 (probably less than 20,000 miles since they been on the car)

How are Sachs Super gas struts? Any feedbacks?
