Thanks for the post, what shock oil, piston and spring were you running or did you leave the same set-up as you were using with a long pack? As for mounting your esc in the middle, i did this on my b4.1 and ended up not liking it, it might be different on a t4.1 but on my b4.1 it felt unbalanced front to rear and to get the feel right i had to add a lot of weight under the battery and even then it didn't feel right due to the added weight and now i'm back to standard electronic mounting positions and i'm way more happier, more steering and same amount of rear grip as before plus the car is a lot lighter since i dont have to add weight. Not saying you shouldn't play around with it but just giving a heads up.
