I have driven my car on the street with a sure grip, detroit locker, and its current spool.

The sure grip went by by as it wouldnt hold up with the power i have currently at the track.

went to a detroit locker and absolutely hated it. Getting on and off the gas was downright creepy with that thing, it comes in last place of the three, for sure.i hated it on the street, even compared to a spool.

I currently have a spool, and dont drive the car a lot on the street but occasionally do, made a 30 mile jaunt several weeks ago, with no adverse situations arising, just scuffed up the tires a bit.

For very limited street driving in dry conditions, i wouldnt hestiate to use a spool, especially if the car sees a good bit of track time, where having the spool will shine.
