solid motor mounts, what do you think of this opinion Options

this is from PMO's ad in the october '03 panorama.

I was thinking about solid motormounts for my racecar but this article makes you think. Maybe the 911 clubsport mounts are better.

Tim...interesting...that exactly echoes the story I was alluding to here in SoCal. 914-6 3.2 race car that had PMO's. They couldn't get it to run right, even with significant pro dyno tuning, so it was converted back to Webers. Makes you go...hmmmm....

Andy - I think on the 914 the trans mounts make the biggest difference in keeping things "in place" when shifting and under accel/decel forces; I am not really sure how much benefit the front mounts add to that. The main place the added stiffness can be felt IMHO is when downshifting under decel and especially also under g-loads; like those turns where you are going uphill, downshifting, and turning sharply all at the same time. With squishy mounts the gear you are looking for tends to "move" from its normal position on the shift linkage. I guess the trans is actually moving a slight amount on its mounts, which is exaggerated by the looong 914 shift linkage.
