I thought that they got this sorted out after the mount problems in the 1G neons. I'm assuming you have a 5 spd, so I would suggest either getting inserts, and purchasing a filled front mount. I'm running a Deyeme firm mount as my FMM in my neon and it is amazing! it makes a little extra vibration at idle but is unoticeable at speed. [8)]
however if you really want to firm things up add filled mounts all round w/ a solid rear
