If you want to play short wheelbase car, the best way is to go with either Atomic or PN motormount, some of these motormounts are mid-motor mounts and can allow you set up 90mm or 94 mm wheelbase. I have a MR03 with PN 90mm motormount, powered by an Atomic AD stork motor which is pretty fast and is fun to drive and is fun to be watched.
Yesterday, I try a new setup of my MR03(wide) with PN 90mm motormount, I put a 911 GT1 body on it and powered by a PN 39 turns motor. After several runs with very little changes in setting, it was fast and stable. I will put a handwind motor into it next time.
