To be honest, probably more a reflection of the chassis and overall handling dynamics of the vehicle, than LSD and tyres alone. My Bogan special-R didn't even remotely behave like that - was very much more planted and well behaved.
I'm on an 8/6, 4/3 roster. Fly-in days are Tuesdays. Fly-out days on my 8 day swings are the following Tuesday evenings and Friday evenings for my 4 day swings. Currently up for a 4 day swing.
Reminds me of my old FG XR6T in the wet - roll-on in pretty much any gear and as soon as it got a whiff of boost the back end jumped out. Good times But yes, sounds like it's the tyres.
Oh really? See, mine could handle being loaded up ok. My old man used to have one of the really old magnas (which he thought was a really great car) and it was an absolute POS. I'm under no false pretenses about my own magna...but it served me well with minimal issues for like 5 years.
