I think theres quite abit of difference between the TRD mounts and oem! When i had my mounts realy solid it always felt like the bottom gearbox mount was going to snap off when changing gear fast as theres no play what so eve! Where as i never had that feeling when i was running TRD mounts on my old V! And the polly ones dont need to be pressed in dude they just sit in the mount its self!
