if you think the 3 nm is enough for you defenetly go with a new wheel but i would reccomend you the 9nm base i have it and it has so much detail and with the 9m peak torque you can go with 6-8 nm for a long time without it getting hot but also some laps on 9nm but it gets very hot in my oppinion. in my oppinon i would upgrade my wheelbase if i were u. hope this helped ^^
