Help with exiting corners

[barry]

Hi,

My Tamiya TA-05 spins very easily coming out of corners on my local asphalt track. As someone who has been away from the hobby for a while, I could do with some help. I've altered droop, toe-in, and camber, but still can't seem to solve this. I've heard of people changing to a lighter grease in their diffs to make it less likely to break traction - can anyone tell me if this is worth the effort? Is it possible to 'loosen' my rear diff somehow?

Many thanks,
Barry
