Bearings
 

Are ceramic bearings worth the money?

If you're a pro/semi-pro level driver, yes. For club racing and bashing $1 bearings are more than adequate.

Almost always the answer is no.

ceramics bearings are useless in offroad racing and doesn't give any significant advantage at all. Even in circuit racing.
$1 or less bearings are adequate.

In what application?

IMHO, not worth it for the driveline. In an engine, most won't notice the difference.

A good steel bearing is better than a crappy ceramic one....

I was lOoking at getting some to pit on my diffs and use the regular ones in my hubs.

It's like many of the hop-up available for these scale cars. Will it make you a second/lap difference, or make you car noticably faster? No. Will the difference be noticable to a novice or someone who doesn't drive as much? No. Are there benefits that can be attained, that are noticable by someone who drives alot (someone who can notice small setup changes in the behavior of their car)? Yes.


Like ceramic bearings in the engine, ceramic bearings in the drivetrain will allow your tranny to spool up faster with less effort, and spin longer/freer off-power. It will make a noticable change in off-power turn speed, and you will see your efficiency and therefore run time increase a bit. There is also a small weight reduction -- especially unsprung weight in the hubs.

Again, is this going to take your racing to the next level? No, only practice can do that. But does it offer some small benefits.

BTW, for most I recommend steel, as they are low maintenance (throw away)...but for those looking to squeeze every bit of performance out of these cars, I recommend Ceramics for the drivetrain (everything except steering and clutch) and steel for those.
