Or a 2-way. IIRC

Spools are the BEST way to go. For any car.

For the street, or lots of turns…very very bad. Axles shoot out. Chew the shit outta your tires, wheel/axle bearing. All kinds:)

Every tried pushing a full drag car with a spool? Next to impossible to move by your self. That’s straight, never mind turning! HA
