Acer sells excellent products. You can try rc4less.com for other bearings that are supposed to be even better.

Default Acer Bearings

I recently purchased Niftech outdrives and rings, Installed Acer ceramic balls and now have a ULTRA smooth diff. I'm very happy with the purchases.

Does it free up the drivetrain and make it free wheel longer?

Default free spin

I don't have ceramic's where it would matter for "freespin" I have ceramics balls in the diff which makes the diff very smooth. I'll prabably get "slammed" for this, but I don't think free spin matters that much in racing. As long as there is no binding, 2-5 seconds of "freespin" is fine. (In my opinion)
The diff is what allows the outer wheel to rotate more then the inner while while in a turn. Mine was kinda rough before I rebuilt it. After the rebuild, my car had more steering and was easier to control throughout the turn. I also it didn't drift down the straights.

Well, a bearing is a bearing, but ...
I'm using ACER bearings, phenolic ones, with great success.
Just keep them clean and well lubrifacated.

My theory behind the whole free wheel thing is, the longer you car free wheels, the easier it is on the motor. With less friction in the drive train the better, because it does not strain your motor as much, thus making it run cooler, longer. Now when you build the drive train you want to build it as light as possible, then you want to make that free wheel as long as possible. Anybody can make there car free spin for a long time, if they add all of the steal this and the steal that, but now you have a ton of rotating mass and thatís bad. Thatís the reason why Iím looking for smoother bearings! I know of this guy who has this car that free wheels for 18 sec. and he always has the fastest car! So if you ask you me, I think it does make a HUGE differnce.
But hey thats my theroy.

What do you mean "More Maintainance"?

I thought they were sealed, so how would you lube them?

Are you leaving them off or putting them back on?

I currently have the ceramic Acer kit for my TC3. I have run many other types of bearings...from Acer, Boca, RC4Less....
The Acer Ceramic bearing are the best I have ever used. They are virtually maintenance free and I have yet to blow one out after a year and a half of racing on the same set....unlike the bearings in the other kits I have used. The RC4Less Ceramic kits are nice. They may be a "better" grade of bearing but they have the metal shields which will cause more resistance than the red seals that Acer uses. I like my Acer units much better...I don't have to clean them out, lube them or spend hours pulling carpet fibers out of them.
In my opinon, buy them they are the best I have used.

They will help your car free wheel better. It took me about 10-15 battery packs to break them in. But depending on the car you have, it will take more than a great set of bearings to help your car free wheel. On the TC3 you have to remove a little material in the diff cases where any bearing will rest. How much material to remove is up to you...for me the test is as follows: I will use a dremel sanding wheel to remove small amounts of material at a time...they fit the countours of the TC3 diff housing perfect. I will put an outdrive bearing (just a loose bearing) in the case and screw both halves together. I seat the bearing iun the case and rotate the diff case 180 degrees. If the bearing falls out of it's seat then that is all the material I will remove. In doing this, you will make sure that your diff cases are not pinching your bears causing any unnecessary friction.
My car never free wheeled and now while using the Acer ceramic bearings, Acer Ceramic diff balls, a composite drive shaft, composite dog bones, composite outdrives and IRS aluminum input shafts, I can get an honest 10 seconds of freewheel...I could make it free wheel much longer if I used heavier parts. I am not convinced that a car that free wheels has faster lap times. I have NOT noticed a difference in my laptimes.
I feel that it doesn't matter how long your car free wheels...BECAUSE THERE IS NO LOAD ON THE CAR! Under all driving circumstances, there is a load on the drivetrain. This is the area I would concetrate all my efforts...just becase the car's drivetrain works well with no load, doesn't mean it will work well with load...or under driving conditions. I would concentrate my efforts on this area. You didn't mention what car you had but in my case for a TC3, I made sure that the grear mesh in the diff cases was not tight and played with the shims in the diff and the input shafts.
Sorry for the long reply...hope this helps.
Joe
