I run 500k rear diff and 1M front diff. I think your rear diff is way too soft. I run the car quite stiff running the new 39.5lbs hard springs. I've found that the GRP wheels rub the steering blocks at near full lock and you can't actually achieve full lock which could contribute to your understeer issues. Like I said I really don't like the GRP wheel/tyre for several reasons. Are you running the 0-degree steering blocks? These would also provide more off power steering.
