what size swaybars are on the front and rear of my 04 ? and if i wonted to change them how big should i go?

 

Not sure what size are stock, but I've got the Callaway swaybars on my C5 convertible and they make all the difference in the ride and handling. You can type in "Callaway swaybars" into your search engine and it should give you an option to look at Callaway's website. This should give you specs on the bars and I'm sure that any reputable brand in that size would serve the purpose just as well.
