My 2006 S is needing caster bushings. So, while in there, I'm going to change everything that is being R&R'd. So, comes my query...is my stock sway bar 22.5mm or 24????

 

Front s would be 24

 

Neither... The stock is a 16mm.

 

Stock is kina wimpy...
Us cars actually had a smaller swaybar than euro cars on gen 1
Not sure if sport option made a diff or jcw made a diff....but s to non s was a change...
with so many varriations in our cars, and so many mods done, be safe...just measure!!

 

You can identify the stock pretty easily. If you look at where it connects to the linkage and it has only one hole it is probably stock. If it has more than one setting then it is likely aftermarket and could be several different sizes.


Pretty picture to help.
