I never had an FK04...but I'll see what I can do for you
Are you running foam or rubber tires? I will assume rubber tires
I would say if you have a multidiff in the back that might be your problem... you need to run a regular diff! If you have a multidiff in the back...set to a one way or a spool...then you're not going to get any true differential action and as such it will be very difficult for you to put the power down.
Without knowing the rest of your setup it's really hard to say what you need to do ... I would make sure your suspension is free, the sway bars aren't bound up, etc.
Check the camber... try 1.5 or 2 degrees of camber in the rear
Make sure the sway bar is not too stiff... I'm not sure what size sway bars that car had... but I wouldn't run bigger than a 1.4 mm sway bar in the rear...in fact I'd try running something smaller for your situation.

I have changed the position of the rear shock and has made a small improvement but still keeps spinning out of corners it has a a oneway diff in the front and a multi diff in the rear thanks
