The manual on my 98 Firebird says to push it when starting out in icy or slippery surfaces. Living in Florida where it rains frequently, I use it when I'm at a red light on rainy days. It really does...
Yes it will. Any rear end from 1993 to 2002 will fit. All the parts are interchangable from 1993 to 2002. In 1998 the front end was changed a little but the rear end stayed the same.
