Nothing pronounced...The PC style drivers do not ride on top of the metal clips...so there is no driver to clip contact... with the PC style...just rubber to rubber until it starts to ratchet and then the tooth will touch the clip.
A lot of people assume that when they install toothed drivers (AKA Extro or Combo drivers)...that the driver is causing the vibration.
That may not be the case....
Here are some other things that cause vibration when switching tracks/drivers
1) Taller lug tracks may clear the tunnel when sled is warm dry ...but the paddles slap at any ice snow buildup after running because of less clearance or stiffer lugs, this is more pronounced with 3" tracks... Less prevalent on the RMK models with the front coolers.
2) Because of the decreased lug tip clearance there is actually "pulsation" from the paddles pumping air and air/snow mix out the front of the tunnel.
3) With a smaller driver... the internal drive "nubs" on the inside of the TRACK can actually rub on the front swing arm...Especially when you are not running correct factory track tension...these nubs "buzzing" on the tube make for vibration.
Loose tracks loose performance... don't let anyone tell you that because they can pull the track around on a lift easier with a loose track that this allows for more power to make it to the track... a sled on the stand and a sled on the snow are two different things.:face-icon-small-win
4) If both the extro teeth and internal drive teeth are not centered in the windows and between the nubs... you will get vibration there... BE carefull and TRIPLE check that the drivers sit center between the internal drive nubs and are not rubbing on the sides of the track windows.
