Do you know if the stub shafts and gears are upgraded, that would make a difference.
I am not at your power level (850 and 640 NA) but have had no failures with Hoosier A6 335x30x18 because the car is so light it can't hurt itself.
I am quite sure drag radials would break something on a hard launch though.
I am running an aluminum Salisbury very similar to the Jag unit with 30 spline
stub shafts and 3:31 gears, stock half shafts with drag race U-joints.
