Depends, stock bars with stock bushings can effect strait line performance.

The reason, The factory bushings are rubber that bind when moved from there settled position meaning that even unattached they will want to return to the position they were tightened. So as a result they tend to act as additional spring rate (ever so slightly) and will reduce weight transfer onto the rear axle. If you have aftermarket poly bushings with lube they will move freely no bind = no problem.

Ron,

Do you think it would be worth it to just purchase a rear sway bar?

Well, it depends on your setup I personally run a reasonably sized rear bar simply so I can reduce the rear spring rate and keep balance in the car.

I will say that it would be worth going to an aftermarket bushing even on the stock bar as it would eliminate any binding associated with the factory rubber body mount bushings.

Only track I do is the drag strip, and occasional "spirited" driving on the street. I know they have aluminum bushings but not sure about polyurethane.

Yea, I got no idea but I really never deal with drag racing.. I know the front bar can simply be removed but I have no idea of the advantages disadvantages of the rear bar size but from I hear they are generally helpful to keep the rear bar as it reduces twist/helps with wheel hop and keeps both wheels planted more evenly. I am going to guess though that in drag racing you can go to far with the rear bar size but I am not sure.
