Yeah, i don't know where my head is at.. ;) I meant RPM..

I agree, though. They are strong rims and very light as well!

Hmm, I wanted to ask you about this. Some 40 I have seem to be wobblers right out of the bag.
I always thought they are damaged from crashs, but now I believe some are just bad when they are new.

I want some proper alu 40's one day.

Well, the chrome velo 6 seem to be made of a harder plastic (vs. the dish rims), so they probably won't wobble out of the bag, but the yellow dish wheels I have make my truck look like it is limping down the track! I like the smaller tires for racing anyways!
Aluminum 40 series wheels look sweet, but for racing, I will stick to plastic myself.

3racing make some nice looking 40 series aluminium wheels. Don't know how good they are, but they do look very very nice.

Well, I thought it's the stub axles, then I suspected the hexes, and I think I can rule out everything now. I made a lil device to true my wheels, and I have 2 Velo6 Chromes that wobble like crazy. They have no visible damage.

Did they wobble out of the bag?

Yes, they did.

Only two out of 12 are bad. But if I spin them on my "true-er" none of them is really perfect. But like I said, only on two would you actually see it when the truck runs.
And yes, I clean out the hex-hole and tighten them proberly. My observations were reproducable.

Well, you won't see me running 4 series wheels any time soon. Have you tested any Revo wheels?

The Revo stock rims are flawless, center-wise. But they are rather weak, I think. Also, the stock Maxx rims are perfectly even!

I'll be putting my crime fighters on stock maxx rims

I hear the proline mamba rim is the strongest plastic 40 series non 23mm rim. I've also heard that the sport maxx rim is pretty tough for the standerd size rim. Those cfim fighters should be the ticket just about every where.

ditto

What about the dace adapters? Or is this for the roller. I'm undecided as I only have a .18 and not sure if I will strip out hexes very easiler.

I doubt that you would strip out hexxes just have your tire nuts tight and locktited. It took a 10L and 16 cells to strip out standard 40 series bow ties i dont think that a .18 could do that even if it was eb moded. Stock maxx rims are just about the strongest rims out there IMO.
