Solid Motor Mounts?

The urethane inserts work REALLY well.

And for the asking price, they're hard to beat.

Solid mounts are responsive, but they shouldn't be used without chassis modifications for strength. They are also very hard on aluminum bellhousings.

So, if you're running an automatic transmission, you might want to reconsider. If you are running a stick, you may want to upgrade to a scattershield for better driveline shock resistance.
