Car has very firm ride in the front,I have Bilstein inserts in Boge struts but the ride is really bone jarring to the point that I have disconnected the swaybar to try and soften it up a little which it did.
Previous to unhooking the swaybar I couldn't even bounce the front of the car with my own weight,needless to say the car isn't that nice to drive (IMG:style_emoticons/default/sad.gif) . Is there an easy way to check the size,are they marked on the ends? I strongly suspect they are too larger diameter or not setup right (indexing ?) maybe,any helpful suggestions guys,thanks in advance. PS front is only lowered a small amount. |

IIRC they were originally stock only 16 mm front & 15 mm rear on both the /4 & -6, or I may have that Bass-ackwards.
FYI - My `73 were stock, Boge struts with classic Koni Sport inserts, lowered an inch & all front bushings replaced back in 1980-83 resto/rebuild, & it rode fine without any harshness nor bump steer. So maybe the bushings noted above & proprer smaller sized sway bar with smooth yours out? (IMG:style_emoticons/default/confused24.gif) Here are the back-in-the-day Road & Track spec for my 73 2.0, but it doesn't list the sway/anti-roll bar sizes....  Good Luck!
