No I'm running the SP. only due to not having access to split packs from my Primary sponsor. From what I understand those having these fit issue's are cutting the body about 1/4" off the bottom cut line to allow a bit more room under the body. This mounts the body slightly higher on the chassis giving the room you need to get some of the bigger packs under the shell. Also some have put some shims under the battery mount posts and using a longer screw to get more room for the packs.
Please let us know what you come up with to get the fit you want.
