I have a 1977 924 that will have Euro pistons, performance cam, and weber carbs.

I'm getting ready to put engine back in but I am looking for motor mounts. This websight has different types listed and one is a "competition" mount. While this is not a true track car I do plan on bringing it down a few days out of the year. Should I go with the stiffer performance motor mounts? has anyone tried these? will they make the car much harsher?

The non competition version is more than stiff enough, in fact some have complained its too hard/noisy. Competition for race car only.

Its pretty cheap to swap just the rubbers if you want to change your mind. Ive tried both compounds, and im now back to stock mounts filled with polyurethane instead, much better
