I rode my buddies and expected more from engagement to where it really spools. He had the mta. I would save some money and just do the basic kit with gt2860. Supposed to be way better on bottom. Don't get me wrong, his ran good but was just lacking from right when it engaged to when the power really hit. If you were going 5 MPh you wouldn't even notice it but if you want to set sled without really going anywhere you will. Burandt took it off one of his sleds and put a GT 2860 back on
