I have a '05 AT Coupe with the Sport Package option. I am thinking about installing swar bars when I do the exhaust. My question: Is there an added benefit to having sway bars with the factory sport package? Or should I spend my money on another mod?

Thanks in advance.

 

yes there will definitely be benefit going with aftermarket sway bar, you will expereicen much less body roll with a good brand and you will have adjustability, can partly compensate for understeering or oversteering and general handling.

 

Does anyone know if the current sport package bar setup is the same bar size as the Stillen? If it is then what is the difference?

 

i'm pretty sure the stock sways are simliar in size and dimensions to the stillen. but the stillen is stiffer and adjustable i believe.
