I'm just running JWT so 850 would have been fine.
I run 1300 because it kills off the vortech rattle and makes my ATS dual clutch more forgiving. I could get by with 1000 rpms, but I like 1300 a little better. Actually I'd probably like to lower it to 1200 next time I go to GTM

it just sounds a little louder and more aggressive
sounds somewhere around a billion times better than the 'broken rocks in a can' sound the vortech and my clutch will make if the idle is anything less than 900 rpms. Going more than 1000 rpms actually makes the vortech sound quieter and smoother at idle
stock Z's don't even sound like they're turned on to me when they idle

The solid motor mounts are... Well lets just say that you know a car that has them when you drive/ride in it. I built my car for track purposes so the increased vibration is acceptable to me.
It seems there are people on both sides of this fence but I would agree with those who would probably not recommend them for a daily driver. On the plus side, now that my car is like a giant vibrator, maybe I will be able to pick up more girls in it

i think most of the guys that have the solid mounts got them from me when i was making them, so kinda interesting to see the different opinions.
i built the first set for my car and i really didn't even notice a difference when i put them in. most other cars i built them for were V-8's, and because of the firing order, you really feel it then!! but to me, that is kinda bad azz to see the car shaking at idle, haha. little intimidating really. for f/i Z/G's, the plumbing is so tight in the engine bay that keeping the motor solid in relationship to all the other parts gives a touch more protection of the hoses coming loose. i personally made the mounts shorter so you can fit a taller plenum spacer and get a lower cg. i am able to run a 5/8" spacer and still have about 1/8" off the stock strut bar with no chance of it ever hitting.
for a track car, yes, all your throttle, decel, and clutch inputs are now solid rotationally. personally, i would not have it any other way for my own car, even if it only sees mostly street driving. i am VERY much in tune with my car and like to feel every single last thing it is doing.
imo, the benefits far outway the slight negative of a hardly noticeable (atleast to some) gain in vibration. i would be rocking a caddy if i wanted plush, hahhaa.

oe knock sensors are calibrated to oe motor mounts and solid mounts increase the potential for false knock counts.that being said the previously listed benefits cant be denied.
