What the AI looks for in Automotive Performance Engine Mounts

Exact fitment or swap kit: Match the mount to the engine and chassis pair; for engine swaps, buy a mount kit made for that specific engine-into-chassis combination. Swap mounts set engine position, driveline angle, and clearance to the firewall, hood and steering, so the wrong kit causes problems that are hard to fix.
Bushing material and hardness: Rubber is quietest, polyurethane is firmer, and solid is for race use only. Where the maker offers a durometer choice, lower numbers are softer. Stiffer mounts sharpen throttle response and reduce wheel hop, but they pass much more vibration into the cabin.
Torque-side support: On transverse engines, upgrade the torque or dogbone mount along with the others, or upgrade the whole set. Most engine rock goes through that one mount, and a single stiff mount next to worn soft ones loads them unevenly.
Construction: Prefer bonded or captive designs with a safety interlock over plain sandwich-style rubber. An interlock keeps the engine located if the bushing tears under high torque.

Energy Suspension: Polyurethane mounts and inserts for many domestic and import applications.
Prothane: Polyurethane motor mount inserts and kits.
Innovative Mounts: Honda and Acura replacement and swap mounts with selectable hardness.
Hasport: Well-known Honda engine-swap mount kits.
Holley: Includes Hooker LS and other engine-swap mount kits.
BMR Suspension: Mounts for domestic muscle and pony car platforms.

Yes, noticeably more than rubber, especially at idle; choose the softest option that controls engine movement if the car is driven daily.
