Tires I found some foams awhile ago at towwer hobbies made by Jaco for the Tmaxx there the largest dia foams I have seen but I dont know if they are still avalable?
Layout wise I found in my CRT conv everything fit and was ballanced running the 1515 motor forward and duel packs in the back? pic 1
On my CRT.5 conv I tied the motor mount into the battery mount that runs from the front of the chassis to the rear pic 2 I found this eliminated just about all the chassis flex and made the car alot more stable at speed vers a friends CRT.5 with a std motor mount? If you can incorporate a mount like this in the XTM with it's exessive chassis flex it will help keep the car going in a straight line at speed.
Weight? get rid of as much weight as you can my CRT weighs in at just a little over 11lbs RTR with 2 8000mah packs you should be able to come in under 13-14lbs RTR?
Just a few things to think about when you are laying everything out.
BTW What KV 1527 motors did you end up getting?

Running 2 1.5D's. Will be running 12S through each motor.....so both will be spinning WAY over RPM's.....probably not good
, but I will try it.
