XRS upgrades ?

[andys]

A few questions about the XRS / X10.

I've got a nice new XRS and have just aquired a used X10 to use to upgrade it.

Which bits should I swop over onto my XRS ? Obviously the rockers and steering metal bits, but what about the actual chassis / wishbones etc, are they really a different material, as the look the same ?

Are the shocks any different inside ?

Also, the diffs on the X10 i've got are shot, are the diff balls the same size as say losi ones as i've got some of those kicking around ?

Cheers.

Andy.
