Just replaced my welded diff with a Quaife ATB unit on my ITS240Z. Last weekend at Sears Point I experienced extreme wheel spin on the inside drive wheel. I was leaving 50ft strips of rubber out of T2.

Quaife support suggested I am lifting the wheel off the ground (ATB needs some resistance to work) and I need to soften my suspension to get this working. Have others seen the same problem?

My setup....west-coast setup...:-)
Front: 325lb springs, Tokico illumina set to 5, "Big" sway bar (I need to measure)
Rear: 380lb springs, Tokico illumina set to 5, "micro" sway bar.

Any thoughts?
