To be clear I have two separate issues, likely with different causes.

The ABS failure/full lockup I feel might possibly be due to the diff. The Nismo pro 1.5 is damn near full lock up all the damned time. it's quite obnoxious. I THINK that under hard sudden braking in a straight line the rear is locked so the two rear wheel speed sensors are in sync, the resulting nose dive lightening the rear and the fronts getting the majority of braking force need only lock in sync for a millisecond for the abs to think all for wheels are stopped and not engage their pulses. Pure theory, didn't have this issue before the diff swap, stiffer springs might aid in reduced weight transfer, my suspension woes are another topic all together.

The "ice mode" issue, i did have before the diff swap, though disconnecting the yaw sensor had fixed it, it didn't. The MK60 swap again is not legal for the classes I compete in. Might not be a real performance advantage over a correctly working stock unit but I sleep better knowing I play by the rules.
