The spool will accelerate the tire wear a lot. If you decide to run M/T drag radials don’t get caught in the rain with a spool, or if you do, keep the speed below 30 and STAY off of the thruway. You won’t hurt the axles in turns, the tire scrubs. 35 spline axles are a little stronger than rubber tires.
I know you like to drive your car a lot and only frequent the track here and there, so I really don’t think a spool is for you.
