Im posting this in the SC/TC section because im sure most in here have alot more horsepower than a stock Maxima.
I notice lately my motor moves so much under a heavy load that i can actually feel it rebound in between quick shifts at higher rpm's which worries me and makes the car feel loose and slows it down. I know the tranny mount is 6 months old and all the others look fine also.

I have the ES MMI's which need to be put in but need to do rad support before i do that. My old 03 had a NWP tourqe link which was perfect but on the new car the blower sits where the link would go.

Is there a stiffer trans mount i can buy ? Or should i man up and fix the rad support and throw the MMI's in ? I know there will always be some movement but look at the way the motor rocks back and forth at 0:25 , Keep in mind that's a 4th gear pull so i can imagine how much it's moving in the lower gears. Thanks in advance for any help.

 

I didn't see much movement but the front to back movement would be more like the front and rear mounts.

 

I was just looking this up and people change one or both front and rear mounts to something stiffer usually polyurethane inserts.
