moroso solid motor mounts... good or bad?

i was really looking into these mounts because i need new mounts and solids sounded like a plan to reduce torque loss, but my question is, are these good for my daily driven car? what are the pro's/con's? thanks

Most people would say to replace them with stock rubber or even poly. Solid i understand is way too uncomfortable for daily driving.

another piece of interesting info is a lot of times your motor will sit higher with newer mounts

On an old Impala street car I had years ago I put a solid mount on the left side, and a regular mount on the right. It was a good compromise.

It'll raise the motor for the same reason new poly's raise the motors, the old ones are just flat worn out.

I dont think I'd recommend solids for a dialy driver, you get a lot of chasis vibration/feel through the steering wheel and car itself "feels" rougher. It took me some getting used to last year when I installed mine, at first I thought something was seriously wrong with the car, but after some buddies rode with me, they said their's were the same way with solids.

I liked my Poly mounts I used in the past and would recommend them, unless you hve alot of HP. The truck I race was built using Poly mounts for some *** awful reason and against my wishes, but it's not mine, anyways it dynoed at 555hp/505 tq and this thing wants to jump out of the engine bay with the crack of the throttle, we ended up fabbing a engine limiter so know the engine is rock soild again. 5/8" rod ends bolt to a bracket on the chasis and a big bracket we fabbed to bolt to all the accessory hols in the head to distribute the forces, works great and easy/low buck solution to buying/installing solid mounts that you really only need on race day. You could even make the limiter on a quick pin system so removel/installation takes seconds instead of 1 minute.

I've had the Moroso steel mounts on my 92 (upper, lower and transmission) for four years. You feel the engine/drivetrain vibration a little more, but for me, it's not unpleasant. I've run them on every Camaro, Nova and Chevelle I've had.
I've never seen them wear out or break, and they free up a little space around the bottom of the motor in a tight engine compartment.
