Thanks guys
I do run a 6.5 but its massively de-tuned. No boost/turbo and only 75% on the transmitter. It's a real pussy cat
Tyres are low profile cut staggers up front and mini pins on all carpet, and some mini spikes on the carpet/wood flooring.
To be honest, I've got a little lost with messing with things, making changes but not really seeing any real improvement or major setback so just left them.
I was due to try some lower cst oil in the diff, but I'm in the process of rebuilding a ball diff, so had hoped to use that.
I dont have any major problems with rear grip, seems to get out of the corners as good as most.
Thanks for all the suggestions, I'll make the adjustments.
