+3, me very interested too.
I recently put on the Brass C and D mounts in the rear and an Exotek Alum Wing mount on the rear to help with weight at the back to reduce the out of corner fishtailing for more forward bite.
I run the large brick square pack and have the Factory RC strap and will be looking at the Shorty packs.
But it is just competing with the Rear Motor cars out there on outdoor tracks.
