  • We recommend every 3-4 track days removing the pinion and  the wheels to check for any necessary maintenance needs. If the bearings feel gritty or have reduced roll, remove bearings and clean with a citrus-based degreaser & lightly oil with a premium high temperature lube/oil like our Rc Speed Secret's 2 in 1 SPEED LUBE Cleaner & lube all in one. Car brake parts cleaner will ruin your bearings and is NOT recommended.
