Strut Mount help & sugguestons

[996C4SC]

Hi All, Looks like I need to replace my strut mounts. What is the Porsche part number for the front strut mount for a 1999 Porsche C4 Cab?  What is the different between C2 and C4 strut mount because I see the price are two times for the C4s.   I saw several after market parts but not sure would be going that route.  I have gone to couple auto cross events but not sure I can live with an after market one for daily driving.  Current my suspension is ROW M030.  Any suggestion would be appreciate!

I replaced the front strut mounts on my C4 a couple of years ago when the started clacking. The mounts for a C4 are completely different than for a C2 and they cannot be interchanged. In the case of mine the rubber between the frame of the mount and the center sleeve had deteriorated and given way causing the clacking sound. Look around and you can fine the mounts for under $200@, as I remember if was way under $200.

Here is a link to my thread on the problem with some pictures. Take a look.

That's exactly whats happening to my car. I updated to ROW M030 package 2.5 years ago and I was debating to change the mounts out but decided not to do it. Now it's failing and I have spray some silicon grease to calm the clacking and it kinda of work at this time but I really have to change it out. BTW when you turn the 21 mm bolt nut on top of the shock strut (#1 in the strut diagram) does it suppose to move or turn in free spin with the washer? I think the torque spec is 43 ft-lb. I used an 3/8 allen wrench socket and 21 mm wrench to tighten it. Correct me if I am wrong. Thanks for you input.
