Question Motor mounts preference

My exhaust tips are hanging about 1.5 to 2 inches below the body lip. I believe the engine mounts are original. I may track 2-3 times a year. I enjoy winding country roads. I also feel that when having the trans in neutral and shifting into 1st with a little clutch engagement, 1st gear engages as it should, might be due to worn mounts. Semi solids or solids and what brands should I consider? Please chime in !

964rs mounts are a known great mount to use.
Had mine for a couple years and did a stock 997 transmission mount at same time to tighten up the drivetrain.
Use longer bolts and you can lower the engine to the cross member and still have the motor supported by threads should you need to more access the top of engine area in the future.

Question

911MHAWK,


Are the 964RS mounts semi solids? I'm a little concerned with regards to cabin noise / vibrations. I have seen plenty of folks vouch for these. And I'm leaning towards them. Thank you very much!

I'm not sure if they're considered semi-solid but I'd say no as they are rubber.
The rubber in the rs is stiffer with less ability to deflect because of how it encapsulated by metal vs the OE ones that have the rubber "floating".

Go with the rs and do the 997 trans mount at the same time you'll be happy.

I'm running RS mount also in addition to a 997 tranny mount and have just installed the powerflex tranny mount inserts. Great combo of parts all around. I say don't overlook the inserts as they've made a significant difference in tightening up the driveline slop and I swear the car even handles better now, feels more crisp.

The Porsche RS mounts are a bonded rubber disc. Bonded to the mount on the outside and to the sleeve on the inside. It then uses a set of concave washers to capture the bonded rubber and make sure the inside sleeve can never be ripped out or have excessive movement. They do transmit transmission noise. I never noticed it with my 2.5" Kline exhaust, but when is changed back to a stock exhaust there was a definite whine. People ride in my car and don't notice it, even if I point it out. But being an Ex-porsche mechanic and now a mechanical engineer, i analyze all the noises. I changed the transmission oil after i put the stock exhaust on just so i could verify the stuff on the drain plug and that my trans was not chewing itself apart.

The RS mounts are and awesome upgrade and they are Porsche parts. That was the clincher for me.

How difficult is it to replace the manual trans mounts ? I will do the 964 RS motor mounts based on the feedback. Thanks !!!

Not hard. First time may take like 1.5-2 hrs? The most annoying part of the whole job is working around the coolant lines to remove the two 16mm bolts that go through the mount itself, but overall you just need to drop the two rear-most belly pans, remove a support cross beam, remove the metal protective/support shield, remove the two bolts going through the mount and then two more actually holding up the mount. As mentioned before, don't skimp on the powerflex inserts either.
