Ok, I haven't driven my X-6 (yet), but based on
Elvo's website on RC Handling/Vehicle Dynamics I'd say you could try the following things (IF the basics of your setup are correct):
- Longer rear link (inner ball stud further to the inside) - gives more roll and more grip, especially mid-corner.
- Shocks less upright (mount further inside on shock tower) - it gives more sideways bite, but it is less suitable for big jumps than more upright shocks.
- Less Anti-Squat - haven't tried it myself but I can imagine this might polarize under- and oversteer between on- and off-power.
Also, I've got the advice from an experienced X-6 driver (oOple member janus) to have 3-4mm less droop on the front that the rear when driving on clay. So if you have plenty of steering perhaps it's worth a look what droop levels you're running?
That said, like Elvo said, a full setup would be really useful - if anyone knows the X-6 it's him and I'm sure he can spot what you need instead of getting 'non-specific suggestions' like I gave you
