I used pennies and random stuff from home depot. It pushed the pennies out and was too harsh until it pushed the pennies out, lol. Then i installed a 2J racing insert and its harsh, but it does drive with more response and better shifting, and I didn't shear a motor mount bolt at the track again the last time I went...
I'd like to fill the other mounts with something to help support them, then go down to a RMM that's not as stiff.
BreedT (I think) is making one that looks amazing.
I just has bigger fish to fry than to spend my very few personal hours losing sleep over the motor mounts for right now. But its on the list
