I still stand by my "slow cure" process.
I mentioned the vibration problems that were had with one install, because I figured it could be a problem on some cars. My car has been fine for 10K miles now with both mounts filled. I do get some extra vibration in the steering wheel and floor when the A/C kicks on while idling, but not "bad" by any means.
Chirping your tires in 2nd & 3rd is fun, especially when you can catch a streetlight race challenger off guard with it. Even with both mounts filled, I can still induce wheel hop on wet/snow covered streets, but not to the degree without them.If I had an extra mount at the time I would've done it your way - but it seems that less curing time is okay if your really pressed for time (never enough time to do it right, always time to do it again).
I still occasionally get some hop - but like you it's mostly on wet or sandy roads.
I have to keep the wife happy - which is probably what threw my level of NVH over the top with the filled rear mount - though it did get pretty darn noticeable at times even for me. Like you said though, maybe just some cars are more prone than others.
