Bearings

One of the most critical, yet overlooked parts of your racing kit is a set of precision bearings.  Massive performance gains can be made with the use of quality items such as ceramic & stainless steel.  They don't rust, they stay true, they don't need lubricating and most of all they are FAST.

Remember, the only link between your car and the wheels on the track are the bearings - don't cut corners, attack them.
