I thought about using those HPI post extenders from my Sprint2 on my TT-01 when I cut the posts too low but I found that the TT-01 body posts arent as wide as the HPI ones and the extender wobbled around. I managed to get rid of the wobble with some electrical tape but in the end I just bought a new set of posts for the TT-01 because I didnt feel like cutting bigger holes in my bodyshell and left the posts long for whatever body I throw at it later on.
