Huge difference for drivability/axle torture/rim flex/loss of steering when you try to run spool on the street.
If you run a spool on the street and have any fat footprint, you will have a "purpose" . A "purpose" is a wreck caused because you were warned in advance and you may kill me, my wife, my family membor or one of my friends. If you cause an accident with this feature, you should lose your license forever...........

Sorry I got hostile. KEEP THE RACING STUFF ON THE TRACK.
