Prothane vs Granatelli for lowering motors, which is better and why?
I'm looking to lower my engine and wouldn't mind any performance benefit either of these give because my longtubes are rubbing a bit. Also I'm interested in knowing how the increase in harshness feels as I don't want it too make the car vibrate too much.

I'm wondering which is the better choice. The long answer please.

Ok there is a serious misconception going on here with LT's. They run over the steering shaft, which means you want to RAISE the motor slightly, not lower it. Lowering it will make it worse. OP- you want the regular Prothane mounts, not the shaved ones. Polyurethane is much stiffer then the factory rubber mounts so when the motors weight rests on the mount the poly doesn't compress as much as the rubber, which is what gives you the extra height you want for clearance.

I was told the red and black prothanes are the same?...can anyone verify that?

Yeah they are, the colors are just for looks. I know steeda makes multiple durometer motor mounts, one set for street one for strip. And true, the OP didn't specify if he was rubbing the shaft, I just assumed. Just thought I would clear up some misconceptions.

Another rule of thumb (Running prothanes btw) is to replace the transmission mounts as well. When you do one and not the other you are risking shearing the old ones due the the added stiffness and vibration caused. Personally I love them

I've looked for a long time for a tranny mount. Carr to share where you found yours? Only thing that's close would be the CHE Torque Limiters but it's more of a bandaid.
