Just a friendly heads up. I may be wrong about the % difference between our front and back tires.

Worth checking into.
I've run a staggered set up on my e90 xi for 132,000 miles. I've also changed out my transfer case oil with ATF like 40,000 miles ago....others said my TC would blow up. My front differential was leaking a lot of oil and it still functions and handles 475 bph. Great cars!
