*1 24.5 the wheel scratches inside the body, but was still better than 27.5mm. Check with fresher bodyshell/try someting in between maybe *2 15mm because of the super low front body. otherwise maybe 18.5mm *3 used tires: 1 deg only. Maybe even less. New tires with 2 was quite safe to drive. maybe try 1.5 *4 try soft instead. Had it in the car from last race *5 bumpsteer on used tires 1mm. 2mm was quite safe on new tires.
