when i did my search i saw that the first batch was not that good but since they have corrected the problem. so if the first batch is 10mm the others would be? and whats the difference? was thinking bout skunk2's but heard they have had a lot of problems and a parts dealer stopped selling them and also recommended omni-powers. well i think its set i will in the sometime near future get the onmi-power coilover and the koni yellow adjustable struts. any price range info on the koni's? thanks.
