Spool on the street ?

I ran one on a weekend, 30 miles to the track and 30 miles back, with 325/50-15s.and I think I had 4.88s in it.Or maybe 4.30s,not sure. It was fine in a straight line, seemed to track just like normal. Next day I headed out on the hiway to the next town over, Again on the hiway it was just like my 3.55s and 295/50-15s.
In town was another story, Every turn was an adventure. From plowing, to spinning the inside wheel, to bogging the engine down. And if both rear wheels had traction and I wanted to do a slow-speed turn well that was the worst, 67Dart says jostle, but I experienced JOSTLE.
Come Monday evening after work, that thing was outta there!
