Set of thin shims/washers will sort out the slop, although no SCT is without it for long
All the 2wd's are plastic, bendy where they shouldn't be and have loose bits borderline on how the hell does it go in a straight line/round corners/respond to setup changes... but they are cheap, strong and bloomin awesome to race
Save your cash for a Durango 2WD, add the price of bling to the secondhand value of your Blitz and you'll pretty much be there and have a shiny new contender rather than a worn out basher with orange metal bits
