65 because of grip... this was on all-season tires. The turn is funky, it starts out wide, then tightens, then gets wide again. I don't have a limited slip so if I get to that speed that's about where I start losing power on the inside tire, and where the whole car starts drifting out sideways (not literally a powered drift but just an overall loss of grip on all 4 corners) in the first place. Not only that but I have to be careful because if I lift on the throttle I get really bad oversteer which causes me to spin out. It's happened before on an exit ramp, but it was a different one that was a much tighter turn and I just went in going about 15 mph too fast probably. Fortunately I didn't learn a lesson from picking glass out of my arm and having to get my back straightened back out... the car stayed on all fours through about 4 powerslides and I ended up backwards in a ditch, with my brights on, and windshield wipers going. Learn from my mitakes kids.
I don't think that will happen with the new tires but I'm not one to test my luck. I've lived long enough to know it's very bad, but somehow good enough to keep me away from any severe injuries besides a deep cut in my finger.
