I have see what a spool will do to a car on the street. A friend had a Vega with one in the rear, coming from a car show he was following me, and I needed to stop for gas, giving a turn signal and turning end to the station he followed with a little speed and his car started to bounce snd jump off the ground in the rear, not a pretty side, scared the hell out of him. We were running about 35 when I slowed and turned .. Just beware of the spool on the street . PS he got ride of the car a few weeks later
