I'll probably try them out this weekend. However, I'm not throwing away my original bearings just in case.

Does anyone know how to reduce centre shaft wobble?
I just put another new one in, don't want it to turn ugly again. Actually, i looked at the pins and they were even twisted out of alignment! Is this normal? LOL...
(I'm using the stock Alu one...)

HPI's non-US bling
Does anyone know why HPI sells lots more bling and functional hop ups outside the US than in the US?
Take a look at the HPI website in Japan and you will see that HPI has graphite drive shafts, alu spring retainers for the shocks, alu shaft drive cups, alu ball ends, graphite top bumper plates, alu front and rear hubs, alu antenna holders, etc. Even in Eurpoe, most of the above parts are available.
Some of the above stuff is just bling, but some really does improve performance and/or reliability. Why would HPI not sell it in the US?
Any thoughts?

Maybe the bling parts you mention are just new and haven't had time to hit the US shores. It's always been that way with Tamiya as well- usually a 2 month progression

graphite shaft eh...
Incidentally, can anyone tell me whether its because my drive cups are out of line, or does the shaft just naturally do this? I just swtiched to running mod recently and i killed a shaft promptly. Might be a sad coincidence but does this just happen?
The previous shaft did "sing" at part throttle and on the stand at least practically roared at you on full throttle. I think it has a nasty resonance to it. The new one is very much better but still deforms on the car stand(no load) at full throttle.

Or maybe you can try this. If you run on smaller tracks with tight turns, the usual case is you must use a lower degree C-hub. Instead of 4deg, try 2deg. This way you have more off-power turn in on corners, this would help your car move faster all around the track.

I already tried the one-way and didn't like it one bit. It would oversteer and understeer. It was to hard to drive.
