Driving on rough asphalt outdoor track! Bought aluminium replacements for most of the drivetrain + adjustable motor mount from yeah racing to enable me to use 64p gearing. Also got the metal gearbox joints so I can use the universal drive shafts (cvds) because every I hopped a corner a little or bumped my car the stock dogbones would literally fall out. And the racing steering of course. Also bought some turnbuckles because I didn't like that you can't adjust toe in , toe out and the steering felt 10x smoother replacing the servo arm from the fixed length link to a turnbuckle.
Really disappointed to learn that the tt01e comes with turnbuckles but everything on the tt02 is fixed
When I say 'lock up' i mean that when returning cornering it tends have a slight delay before returning to the middle when I steer left/right. I have a friend driving a tb04 and it doesn't seem to have that issue.
