Default Ceramic Ball Bearings

Can I get some opinions on whether ceramic ball bearings are worth spending the money on? I was looking at the ones Acer Racing offers. www.acerracing.com

Is the new prototype RDX going to be strictly a pavement car or both carpet and pavement?

Opinions vary quite a bit on this subject. I used them in one of my cars and didn't feel any improvement and they were more fragile. I was able to get my regular bearings to spin just as free by keeping them clean and lubed. I do use ceramic diff balls and they feel much smoother than carbide or steel and they seem to last longer. My suggestion is to save the money on the ceramics and just order regular bearings from avidrc.com. They are $1.00 a piece so if it gets gritty you can just replace it.

So now you know what working on a T2 is like all the time...

That is exactly what I use on both my RDXs. Usually get at least a season out of them on my asphalt car and longer on my carpet car.

The Corally ceramic balls for the diffs are really nice too.

You don't hit as much stuff as some other people do. I've had the same hexes on my RDX since it was new, the Mrs. goes through them like they were Pez when we run on carpet. When we run on asphalt, she doesn't hit as much.. magically the hex breakage goes WAY down. They're not overtightened, the narrow ones just don't seem to like repeated blunt trauma. That's the older black style hexes, haven't had a chance to try the newer style yet.

Interesting stuff in those pictures. It looks like the existing roll center blocks are pushed into a new piece and then mounted to the chassis independently of the bulkheads. If that's the case, it will allow for easier rollcenter changes AND we can use our existing blocks, which will make me love Corally long time.

No center steering, huh? I guess it's not so great? Quick release bulkheads all around will be nice. The rear diff looks offset and the front looks centered, which probably means new diff/one-way/spool parts. I kind of figured they would center the rear so they didn't have to retool their spool and one-way, but what do I know?

It's interesting how the topdeck attaches to the bulkheads. We kind of saw signs of this in the other pictures, but it's confirmed now. It looks like it slides into the bulkheads, almost. I suppose that's one way to lower it other than pocketing.

Will be new diffs and one-way as the bulkheads are suppose to be about 5mm narrower. Quick change roll centers with the same arms and geometry of the old car. Need a chassis and upper deck and this car should be good on foams also. Sounds like the center steering has been working with a spool and rubber tires, but for anything else the standard setup is prefered.

Oh, interesting. Even though the bulkheads are narrower, you can see where the outdrives extend out past the bulkhead, sort of the round looking piece. I guess that would keep them from needing to use different/longer CVDs, which is nice. The front pulley definitely look centered, though. It looks like a different piece that inserts into the bulkhead and supports the outdrives beyond the bulkheads, sort of like a modified bearing holder or something. Neat stuff from the Corally camp. I can't say I've seen anything like it before, but I'm sure someone will correct me there.
