Tire/wheel unbalanced effects

I've recently noticed on my Evo2 [and previously on my V1RR as well], that even after trueing the foams, a noticeable shimmy/wobble exists. I've even trued the sides of the tires/wheels and have come to the conclusion that it may be a tire/wheel balancing issue.

While on the lathe or the car, usually the right front and left rear tires [on both cars] behave the same way. I have checked the hubs and drive parts and replaced them with new parts and/or tires with no elimination of the shimmy.

Am I off on this? Could it be an issue of diffs being off set to one side of center? Is it tire/wheel balancing? Is there something I'm missing.

Both cars handle fairly consistent [unless the operator gets too frisky, stupid or daring on the track, LOL] and the settings stay right on mark.

You may have noticed the question in the Xray forum, but was looking for a fast answer [we should all be at the track right now, huh?]

Thanks!

Someone has to have some idea of what I'm experiencing.

Any wisdom to be shared?

If you see it at low speed its just warped wheels. If you only see it at high speed than its a balance issue. That said I have never seen a set of foams so out of balance that they vibrate. They just dont have that much mass to them.

Thanks for the response.

I'll check it out and check for characteristics.
