Default Aftermarket Bearings

Does anybody use the ceramic nitride bearings, like the acer ones? I am curious as to whether it's going to make the car any faster for the $100 investment per car? What has your experience been if any?

I have two identically prepared cars except one has Acer ceramic bearings and the other has the standard bearings. I donít see any discernable difference in speed between the two. Maybe the ceramics will last longer but the standard bearings last a long time too. Ceramic bearings in your diff might be worth while for longer life. No I donít think it is worth the $100 upgrade but psychologically speaking it is kind of cool to have.

That is kind of what I was thinking. Maybe the pros can tell a difference but for us common folk
Thanks

might give an unnoticeable increase in efficiency, but not enough to justify the cost. also, it depends on the sheilding the bearings use. for RC you want non contact steel sheilding, as the contact or rubber ones increase rolling resistance. and with no sheilding they get full of poo.

Just ordered some like yesterday for my 501x.
Belt drive may have better luck with the Acer bearings.
In my B44 im keeping the stock bearings in it due to being shaft drive.
Onroad they are awesome I need a website link so I can see 'em? thanks
