So I just started WOT tuning my car using my LC-1 wideband ( which has made tuning much easier for carb challenged me) and I've managed to tear the brand new mounts after two or three launches. I plan on getting a set of interlocking mounts, but am unsure on using rubber or poly. I had poly mounts on my other car and they drove me up a wall it rattled so much. Mancini sells poly and rubber mounts with an interlock, anybody used either of these? I am particularly curious about the rubber ones because they should dampen just as good as stock and lock up solid on accel. I also plan on running a torque strap as an additional precaution along with the new mounts. Also, I have the screw adjustable pinion snubber and seem to have lost the poly bumper for it. Anybody know where to get this, or a decent substitute. Thanks again for the help!
