I've been through their shop - impressive facility. They do a lot of specialized fabrication work for aerospace industry. Great guys too. I trust they'll get the thing sorted quickly.

Cfjan...my 2007 7GT3 has the solid cup car engine mount illustrated in this thread plus the suspension is completely solid. No issues with the electronics at all and so far not a lot of other things being vibrated loose.

I do it all the time in very tight corners. I ran at Buttonwillow last weekend which has 2 tight turns, one with a declining radius. In order to carry more speed into a tight corner I turn-in while still in 3rd and allow the car to coast a second in the taller gear. I then downshift after corner entry and start getting back on the throttle for track-out. I wouldn't let out a clutch with a high rev load mid corner, but as described above you're in a low RPM stage and feel little effect if any from the downshift. The net result is a much faster corner entry than downshifting to 2nd....

Update:
Spoke with folks at Rennline and they made the necessary modification on the solid engine mount to fit our GT3/RS. I should have the first set in about a week or two. Stay tune

911SLOW, I also have the 993RS semisolid ones on a 997tt that has the full cup/rs susp components. Do you have experienced vibration and/or stiffness issues with those that you are hoping to solve with the solid ones?

The car feels as one with them and I can’t really feel anymore the rear mass moving independently and with a delay compared with the rest of the car.
No apparent added vibration from the semi solids. And they are lighter than oem about 2lbs.
I do consider them a maintenance item and will change them when rubber on them starts to let go. Like the transmission mounts I recently changed.
I was very surprised that Mike reported no vibration with them, it goes against logic since there is metal to metal contact and zero isolation but I take his word for it and besides vibration feeling is quite subjective.
Just want to see how much lighter these are. Maybe I give them a try down the road.

Thanks, I guess I ll check the rubber in mine. I just wondering if the mounts are responsible for the hashness in the back when I hit a pothole.. Or it could be any (or all) of the dog bones, toe links, sway bar, droplinks, cup lower control arms, dymags..! Am curious what P installed on the GT2RS from the above list since ride is apparently pretty decent for the handling characteristics.

I have a set of new wevo ss mounts in a box awaiting completion of this thread before I get them installed... thinking I might just go straight to solid mounts...
