I was researching the diameter of the stock front & rear sway bars so I could purchase new bushings and come across this old thread. Those numbers didn't sound right to me so I did some more searching on other sites and come up with this:
Base / Rs / Gs / ESi Front: 16mm Rear: 12mm
GSt / TSi-Fwd Front: 18mm Rear: 15mm
GSx / TSi-Awd Front: 19mm Rear: 18mm
I just thought I would share this information for the sake of future searches. This was the only thread I could find on 2gnt regarding stock sizes and the previous stated information was false. 19mm sounded too large for a stock front bar on an N/T and 13mm rear just didn't sound right at all.
