How do you know when your engine mounts are bad?
When I was installing my muffler bypass this week, I had the rear bumper cover off and saw my engine mounts. It made me think about how easy it would be to replace them--which made me wonder how you know when they need to be replaced.
How do you know for sure? My car has 63k miles. I know they stretch, but how much? Is there a measurement I can do to see if they're fatigued? Maybe the height of the oil pan off of the driveway?

Leaking? It's very stinky.
Exhaust tips even?
Excessive movement in the exhaust tips upon acceleration, braking, or throttle blips?
Just a few.

I found that when I changed them the car was much smoother switching gears under breaking and turns.

On my 997.2, I guess I had the good fortune of one mount getting weaker than the other first, so I noticed the gap between the top of the exhaust tips and the surround trim was getting larger on one side than the other. Like SoCal C2S noted, both sides came up quite a bit once they were replaced. Note that neither of mine had ruptured so there was no dramatic fluid leak or anything like that.

I did mine at 96K miles and have a DIY writeup on it. My one side was sagging just a bit. Was this "worn out"? I dunno, but I like a project. (pics of the sag in my writeup)
It is very easy work.. there are minor differences in 997.1 vs 997.2 .. different nut IIRC.

Also, watch out for the Corteco vs Porsche parts issue noted in my write up.
After I did the work, I may have felt a difference in that the car wagged less but honestly, it just could have been my desire to feel it. I never felt any difference in shifting before or after and while I don't dismiss what others feel, I can't for the life of me understand why these mounts would have any effect on shifting as the transmission/engine assembly is a solid system and the cables are attached directly to the transmission... it all moves as one.
Fun project and not expensive.

Haven't been able to drive it yet. To much snow and my new wheels & tires were lost by UPS after being shipped by the supplier. Had to re-order and now in my second 6 week waiting phase. Frustrated and cold here in Spokane!
I can comment on the quality however which is excellent. They utilize a nice thick 75A durometer bushing which is supposed to yield a great street worthy ride. I do know of one person who switched from the RSS mounts to NYPPD and said it was a significant improvement. His review is on the NYPPD website.
Also the coupon code "tenpercent" still works as of today which puts these at $251.99 and free shipping! Very hard to beat that deal...

Shouldn't take more than 30 minutes to install them so I would say under $100. I can say it took me under 40 minutes to do both including jacking the motor and taking my time.

Long story:
Company I purchased from realized last minute they forgot to add my new TPMS sensors to the wheels but had already created the UPS labels and had all 4 boxes qued up at the back door for pickup. Someone figured it out and cancelled the labels but UPS driver nabbed them before they could pull the boxes.
According to UPS a cancelled label is processed into a different DC and the chance for recovery becomes next to impossible. I've heard they auction this stuff off.
I was pretty bummed out and had to step away from it for a day. Ended up calling the manufacture directly to explain and see about getting the order expedited. Production manager assured me he would get it through in 2-3 weeks vs the normal 6-8. Won't hold my breath on that one...
Still had to go through a distributor however. Couldn't get the Mfg. to go direct. Ended up processing the order with original company vs swapping to another Dist. Figured they would likely baby sit the crap out of it the second time around.
