Gee, I use CEN 1/8 scale buggy/truggy shocks on my Kyosho buggies. The CEN shocks are actually not bad and can be found on EBay pretty cheap. They are inbetween the old big bore standard (14mm diameter shock bodies) and the new Kyosho Big bore shocks (18mm bodies) the CEN shocks measure 16mm. The pictures show the difference in size between Kysoho and CEN 1/8 scale shocks.
