For all out drag racing with some Big Skat tires, anywhere from +6"-12".
Jumpers and bermers might want a +2, and a good allround might want a +4. It just all depends
Need one? No. Even with my 70+hp I was still able to do fine with the stock arm. Especially if you're trail riding, you're going to be spinning the tires anyway lol. It's just nice to have onekrbdog said:I do little jumping mostly just balls out trail riding here in Arizona.Do i really need one???
