If you locked up the rear and started sliding with the rear end coming around; why did you let up? Aren't you putting yourself in danger of "high-siding" it? From what you described immediately after the first slide/lock up incident, it sort of sounds like that's exactly what you had experienced.
FWIW, I am/was still driving around today trying to get the "chicken strips" a little narrower on my rear tire, but there's so many "Sunday morning" drivers cruising around on this Labor day (holiday over here) that I gave up and went to a vacant parking lot. I ended up doing 20 minutes of really tight circular turns with figure eight's thrown in and now feel that the rear tire is not washing out so much on a hard turn.
Overlooking the parking lot was a gas station, and I went there to fuel up before going home. The attendant there apparently was watching this imbecile driving around in circles for no apparent reason and remarked " You having fun out there...?" I tried to tell him what I was doing but he couldn't fathom it.
In hindsight, it was a little fun after all :lol:
Kindest regards,
