Guess I'll remove some more ballast and maybe add some functional weight in the way of a cooling fan for the motor.

Those geniuses at ROAR. 17.5 min weight is ok, for mod it should be max weight hehe. Those things are dangerous to marshals.

run yours yet Tom ? if so, thoughts ?

heard a few things about this front shaft popping out, but it seems to be isolated to the state of Victoria, Australia ??

no reports from Japan or US of an issue.

Victorians lol I sore 3 zx6's run well at the ACT states but.

For those of you losing your front driveshaft, have you checked your front foam insert? I have not yet lost a front driveshaft but I have run the car 3 times and all 3 times the front foam insert has gotten eaten away to nothing. I feel that this could be a design flaw. Next time I run the car I am going to try a shock o-ring in place of the foam. There has got to be a better solution. I like the way the car drives, but this is driving me nuts.

Well the foam was reduced to a flat ring and the plastic piece was pushed in. Replaced the foam with an o-ring.

Not sure what the ZX6 outdrives are like, but you might be able to also use fuel tubing of the correct diameter - just slice off your own segments - kind of like o-rings. They provide cushioning, and are cheap, you can make the exact thickness you need, and seem to hold up well. I do this with my ZX5 to space the main driveshaft correctly for the Durango diffs. My notes say the outer diam of the fuel tubing is approx 6mm. I'm pretty sure that is 'medium' size with 3/32 inner diam.

Does anyone have a base setup for a loose(low-med bite), rough outdoor track they could share or any tips? This is me first 4WD so any help is appreciated.
