I would like to thank everyone for there comments!.
Huge HELP!!! THANKS GUYS.. 
I’ll take out the locked diff and use the other one I’ve got, I’ll also try a lighter sway bar and maybe some suspension adjustments..
I knew it was me / my lack of driving skills.
. but if this will make a better driver on the track then I'm all for it.
Thanks again for all of your time and comments..
Have a great day gentlemen..
Shaun.
