HIGHLEY RECOMMENDED BY ME!!! Not only do they look unbelievably good(especially if the color of your car matches the two available colors, black and red), but they serve a great purpose. I have a polyurethane tranny mount and these mounts made my car feal great. At first it brought some exhaust rubbing to my attention because it transfers engine vibration to the back of the car. Once i got that worked out, i can't say anything but good things about them. It seems as tho they stiffened up the front end of the car, sordof like subframe connectors but it uses the engine. The power feals like its going straight to the ground. Well more than it did before, but i have a lot of mods done........Sportline Springs, Adjustable Shocks, Panhard bar, torque arm, lower control arms, 480 RWHP LS1(heads, cam, pistons, intake etc.). Anyway im trying to say they work really well with heavily modified cars that would ruin stock rubber mounts like mine did!!! Spohn gets props from me. Im a fan!
