I agree with IROC. Those changes will do a few things for you, but nothing that you will instantly feel as a performance improvement.

Poly bushings will tighten up the reaction of the bar, but will also squeak. Not much gained there.

Tarett's drop links simply afford you the opportunity to reduce any preload on the bar and thereby allows you to better corner-balance the car. Also their adjustable length makes it easier for you to hook up the links to the bar.

Factory mounts tear on cars with fully stock suspension all the time. So don't think that you're safe from mount failure by sticking with stock torsion bars and sway bars. Reason being is the high amount of body roll loads the sway bars so much, due to softer stock main springs (torsion bars). Even with fairly stiff torsion bars and stock sway bars you can still tear the stock mounts. This is because the car still has a fair amount of body roll.

The stock mounts fail two ways. Either the base tears away at the 90 deg. bend, or the nuts pull thru the base. Stock mounts are good enough if you reinforce the base by fattening up the 90 deg bend (or support it with a triangulated piece) and by adding additional meat to the base to keep the nuts from pulling thru. That said, they're still made of thin sheetmetal, so they're a little touchy to weld (easy to burn thru the thin metal). Nowadays the factory upgraded butterfly mounts are around $75 ea. For slightly more money you can get the Buckley Racing plate steel mounts or the Wevo cast steel alloy mounts. Both are very sturdy mounts that should last a very long time. They are both much more beefy in the base than the stock mounts.
