Default strange offset

I got a used JRXS from a guy a few weeks ago and I just noticed that the hex hubs that the wheels bolt onto are thicker on one side than the other.

Is this a tuning technique or just an oversight on his (and now my) part?

Also, for racing, what dimension is the 190mm referring to? The width at the outside of the rims?

Thanks.

Hey Dan usually I use the thicker hubs up front and the thinner ones in back. Having the thicker ones to one side may have been a tuning feature for oval?

The 190mm measurement is to the outside of the wheels. The car will have to fit into a wooden "box".

On the same topic, what's the effect of running offset front and rear wheels?


Mike Haynes,

I know your rubber setup that you've been lending out calls for narrower layout in the rear. I tried making this work, but ran into some problems with the drive shaft bumping into the diff nut inside the left outdrive. Lots of room on the right though. Is there something I'm missing?

If you use the inner hole on the arm for the rear hubs, you need to use an offset hub...they are sold seperately in 0, .5, and 1 degree toe amounts.

Sliding the regular hub into the offset hole on the arm will not work.

For the hexes, it was explained to me that a narrow hex in the front will make a car steer more, sort of like a tricycle...but a wider hex will reduce the rim rubbing on the shock bottom, and allow you to use more d/r. Try both and see what works for you. I try to run the front and back of my car at the max width allowed (190). Different brand rims have different offsets, so which hex you use may change if you switch brands frequently. With Parma, a wide front and narrow rear will be maxxed out. If you use Speedmind or Jaco you can use the wide hexes in the rear also, as they have less ofset to them.

Thanks again Mike! I assume these offset hubs are listed with the older XXX-S hubs (compatible I think)? Can't seem to find a part number for the Jrx-S.

By the way, I've had some front arms on backorder at my local hooby shop for what seems like forever. Looks like even Losi Parts House.com doesn't have any in stock. Anyone have some insight?

Cheers!

Go there for the hub part #s.

You would have to ask Todd about the arms.

Hey guys,
I am picking up a second hand JRXS and was wondering what would be a good setup for stock on a low grip tight ashphalt track. Would kit settings be good?

Cheers

Mike, I left you a PM. I had a couple of questions about your setup that you sent me.

Thanks.

You can either use differnt rear piviot blocks or you can use rear hubs with built in toe.

So if I have a setup that calls for a 0 degree pivot on the rear then I would need to use 2 degree hubs, right? I can't seem to find any of these hubs though. I even looked at xxx-s parts.
Does anyone have a part number for these?

One more question. This setup also calls for using the "offset" hole on the rear lower a-arm. But when I do this, I cannot get the top of the hub to slide in enough toward the diff to remove any postive camber. The axle is hitting the diff inside. What am I doing wrong??

Thanks.
