I just had the TSB driver update completed on my 22 Khaos and I'm concerned. The new updated drivers have drive lugs on both sides of the track windows but my track only has lugs on the inside portion of the track. That means the track will only be driven off the one row of lugs per side and the open windows. I've noticed that the newer 2.75 tracks have lugs on both sides of the track windows. I could use aftermarket drivers to drive on all four rows of track lugs on the inside portion of the track but I heard the polaris kit was smoother and it was no cost. What has everyone else ran into.
