I just ordered Woody's 1.325 inch studs for my 2011 Apex. I called Woody's tech support and they said with that length I should have no issues whatsoever with damaging any of the components under the tunnel. They said that Yamaha makes a tunnel protector shim kit. Do any of you have that part number? He also said you could do it your self by drilling the rivets out and adding some washers and then re-riveting it with longer rivets.
