Difference between upper strut mounts ..stock vs X74?

[perryinva]

Besides the price, what is the difference between 996 343 018 04 (stock, $86 list, same part has been replaced with new part number 997 343 018 00 ) and 996 343 980 08 (X74, $181 list) strut "triangles"??? Trying to find out if there is an advantage to use the X74 one with PSS9's BEFORE I install them...

Bump...no one?

OK, finally got a great answer from Gert, the X74 mount has indeed less & stiffer rubber than stock, and works as a great comromise between stock and monoballs with PSS9s. He's installed PSS9s with both. Another poster on a different board emailed me that he upgraded from USA M030 to X74, and noticed immediately the more robust design of the X74 mount and felt that the difference in the upper mounts accounted for a lot of the steering feel, FWIW. He noticed little if no increase in noise/vibration transmitted to the driver, (of course that may be masked by the the stiffer ride) but then he also didn't have a stock suspension to compare it too. I'm going to go X74, and take good pics of it for future posters.

I'll be leaving the old ones on the original struts in case I decide to put them back in if I sell the car. You always tend to do better selling the upgrades separately. I may go so far as to assemble the PSS9's with all new parts and just leave the OEM strut assemblies together, if I can get them installed for enough less that it makes up most of the difference...Sorry. But, the stock OEM mounts are cheap from Sunset, like $50, or post inthe wanted sections..a LOT of listers have installed M030 sets and they come with new upper mounts. BTW, I'd be VERY careful driving the car with only 2 studs through the strut tower...one of the reasons I prefer 4 stud designs.
