A search for stabilizer bar didn't yield enough info so here's my question.

In the 94 gsr i just bought i found yesterday after crawling underneath that the rear stabilizer bar was the most rusted piece on the car. How important is this? The car seems to drive fine and I was hoping to wait until next spring before I replace it since I want to totally redo the suspension. The car seems to be well aligned.

thanks in advance,

Jeff
