the df03 isnt a bad car when spend the money to upgrade it. its biggest drawback is the type of plaxtis used to make the thing. tamiya really used there cheaper sport hobby grade plastic on this chassis, and not the hobby/racing grade that is used on the ta05 sedan, or db01 durga. the plastic will strip easily, even when you switch over to hex head bolts.
you can always get the KM Koncepts chassis conversion like me. but i got raelly lucky on eaby, and got over 1000 in parts of just over 200. i run mine on a 4600 MM, and its pretty much as fast as i would want on a track.
heres a taste.
