I have copied a few others here and made the following changes to my buggy. I've added a CVT filter in the cab which was a simple project and cheap to do and trying to keep the dust down in the cab I have started to cover up holes starting with the 2 holes for the seatbelt attachment points directly in front of the rear wheels, I also added a pleated primary filter in the cargo box for the engine and these 2 filter changes have allowed me to completely cover the back wall including the 2 unneeded air vents behind the seats with Thermo Tec which I continued to run under the entire length of the center console, I also copied NMK and installed a boot on the emergency brake handle, I installed the Super Atv full flip up windshield which I run open 90% of the time and a rear soft window from Pacific eagle with a zipper on the center section that will allow you to ride with the clear vinyl window rolled up, I don't but it is good for trailering vs removing the whole thing, this window is extremely well made and fits the Z6 like a glove. These changes have dramatically cut down on heat, noise, and dust in the cab, my biggest noise maker now is the front drive shaft, as others have said there is a lot of play in the splines and the rattle it creates drives me nuts, the Thermo Tec helped but it is still there. I also used jack nuts for the entire rear panel and center console doing away with the plastic push rivets, I used black oxide screws and flat washers so hopefully, rust will not be an issue. I also moved the crankcase vent to the top of the air filter box and it appears that I am getting a lot less oil accumulating in the air filter box and the intake tubes, I assume this is due to the mounting position being higher and I believe that there is less vacuum on that line being in the air box as opposed to the small tubing connecting to the throttle body and being mounted before the filter the vacuum on that line should decrease if the filter gets dirty as opposed to increasing when it was after the filter.
