    Are the stock plastic wheel bearings/eyelets from the AR chassis better than the regular ones from other chassis, the ones with the brass eyelets?

    Depends on the plastic type, if it's stock ABS plastic for A Parts then it's soft and will deform pretty quick even with an eyelet. If it's the CF-ABS (carbon reinforced) A Parts, then it's pretty strong and resists deforming much better. The middle ground is the PC+ABS which is neither here nor there, but is still better than stock ABS.

    So in summary it depends on the plastic:

    CF-ABS > PC-ABS > ABS

    The AR chassis as well as the MA and FMA come with POM A parts. This is a low friction type of plastic which is excellent for the wheel bushings as well as stick rollers. Ball bearings will obviously be superior and you may get some quicker wear with the POM parts, but if the only choice is POM, plastic(ABS/PC-ABS/CF-ABS) or brass, I would run the POM.

    If you are able to, its better to switch to the ball bearing types, specially if you will be racing.

    Thanks for the reply, I have cars with 620s or round hole bearings, my question would be more specific, like; if plastic eyelets are a 0, and 620 Bearings (te old ones) are a 10, which grade would you give to the fluorine coated? Closer to eyelets or closer to bearings? Thanks guys.
