I'm biased for Fiero X mounts, very strong, easy install, and simple. Cradle bushings should be poly, aluminum is not necessary and more pricy. Poly is plenty hard.

I disagree on the cradle bushings, they should be aluminum, you already have bushings for the motor mounts and control arms, there's no need to further isolate the car from vibrations, you just add another part to move and wear out by using the poly, on top of that, they aren't expensive in aluminum.

After personally witnessing serious fitment problems from a few local Fiero owners who bought the Purple Rain mounts, I would not recommend them.

The urethane cradle bushings may be stiff, but they're not solid. They still do flex. ANY flex in the cradle mounting is bad for handling. That's why the cradle bushings were deleted (the cradle is solid-mounted) on the '88 Fieros.

Depends... Auto or manual? If manual, I go with Rodney's poly mounts at all three corners with a fabbed front engine mount. If auto, I've used Fierox's mounts. Had good luck with both and no need for a dogbone. -Jason

I mean both are very stiff, aluminum is obviously stiffer. It's a street car right? I guess I'm using mine as a DD plus poly is cheaper that's about it.

All mount brackets use only one bolt for the connection to the mount. No matter how thick the steel is , the engine and trans sit connected by them. Do your mounts use heavier larger diam. bolts?.

On fiero x mounts, the front mount under the crank is held by 2 bolts.

I just bought a set of WCF mounts. all three engine/trans moutns, and their Poly cradle mounts. Worked great, slight mod to the cradle to center the engine.

Pics attached.

10.9 bolts and mount studs > 3/16 and 1/4 mild steel bracket. You'll bend the mounts before you break the bolts

All hardware and mount studs are M12x1.75, so yes, bigger.

Buy your self a nice mig welder and make all your own mounts and brackets that way every thing will line up properly with out elongating holes. It will be cheaper this way and you will still own a nice mig when finished. Dan
