For the front I purchased stock ST162 struts to use as a basis for the conversion. I cut the spring platforms off and welded adjustable platforms in place for 2-1/2" race springs. Toyota Levin Bilstein inserts were used, these had the stroke reduced and were re-valved to suit the GT-Four.

I was fortunate to buy rear shocks which had once been on a Toyota Team Italia rally car. This saved me the hassle of modifying the rear struts to take inserts. They are Bilstein competition units and were actually intended for a Group N Peugeot 205 GTI!! The knuckle mounts were all cut off and new ones (out of 5mm sheet steel) welded in place. They have been revalved slightly for a rally spec GT-Four, and I have since revalved them again for the street. I have fitted adjustable platforms.
