Looks to take a standard stick pack straight down the middle so your battery should be fine.
The Mad Rat or TC02 parts should fit and the TC02-Evo parts should offer upgrade potential. Don't get confused with the TC02C or TC02C-Evo as they are not the same car at the back Front is identical and the TM2 has the same ftont end as well.
