Mr. Lee is right,
theres no point in getting the carbon upper deck. the tt01e comes with an upper brace while the tt01 does not. basically convert your superior tt01 type E to a regular (modded) tt01. It kinda defeats the purpose. i suggest a solid rear spool diff and a front one way. also if you havent found a motor, i highly recommend the tamiya sport tuned motor. it is still 27 turn brushed but more power than stock can and way less energy consumption than a tz. However, if yourgonna keep your esc and use sport tuned, Keep the 61/19 spur pinion combo or you risk damaging the esc (This happened to me).

you can find tt01 parts on ebay or rcmart
