The Scamp had a spool in it. I got caught in the rain once and it made me a little nervous, but otherwise, I didn't mind it. It chirped the tires around corners, but it also made me drive the care carefully. I probably wouldn't drive a spool-equipped street car by choice again, but I'm certainly not against them.
My CJ-7 has Detroits front and rear, though I keep the front hubs unocked on the street. With a 7 inch lift, 35 inch tires, and a short wheelbase, it can be squirrelly in the rain, which I try to avoid. Otherwise, the occasional "bang" from the locker is the only time I notice it on the street. On the trail, they're worth their weight in gold.
Earning every penny of that moderator paycheck.
