Well I am looking to upgrade the shocks on my 75. I autocross at least once a month and seldom drive it on the street anymore. I intend to do the trailing arm and chassis stiffening this winter as well as a 5 bolt conversion. The car currently has the boge front struts. Question 1, are the 914 front strut inserts compatible with the 911 units? Are the Koni struts that much better than the Bilstein ones? And last, do the rear Koni struts have adjustable spring seats like the Bilsteins?
