I've been wondering lately about how practical/manageable a spool would be on a powerful MR car like the GT40. Now I know what a spool is and what a spool does. I know that it makes parking-speed maneuvers a pain, and that it acts as a yaw damper and induces corner-entry understeer, but I wanted to hear your first-hand experiences with a spool. It would also be interesting to discuss if and how one can tune out its undesirable handling effects, or if necessitates a different driving style. Finally would you say that really high power/weight ratios, on the order of 600bhp/ton, justify using a spool?
