Vector Sway bars

[Yamaha Vector LTX GT 2009]

So my brother got the 13 mm sway bar for his 08 vector ltx gt. He took out his old one and we measured it and it was 12mm. So I had to replace my sway bar plastic bushings on my 09 vector ltx gt and when I had my sway bar out we measured it and mine was 11mm. So my Brother put in his new 13mm sway bar and I took his old 12mm and put it in my sled. So what is the stock sway bars for these snowmobiles is it 11mm or 12mm? We got both of these sleds used so the previous owners could have upgraded them. Will My brother see a big difference in his 13mm sway bar vs the 12mm? He got it to try to reduce ski lift when turning corners. We both have the simmons flex skis on our sleds.

11mm would have been stock.

The 12mm bars came stock on the Vector and Apex with EPS.
