bought and installed the street/comp version. very nice peice. big and beefy. has nice welds and all. when i took out the oem UCA it has tons of deflection in the bushing. not that its worn out, just thats how its made i guess. the new peice is very solid and has no bushing movment. on the road it has zero increase in NVH and had noticable differences from the stock peice. i must say, way to go steeda on this one. although they probably arnt really the ones who make them lol.
