So tonight I was out driving and I get to my favorite stretch of highway. Coming off of a rotary, a two lane stretch about a mile long that is always unpatrolled. Sometimes there is a cop on the rotary but tonight there wasn't. So I pull on and for once there is no one in front of me for a good distance. Wanted to see what it can do I nail it, because I haven't found top speed yet, should be drag limited. I go WOT it in third, hit fourth, hit fifth. I didn't get to hit top speed but I made it to about 115 ish. I didn't look because I didn't want to take my eyes off the road. I pushed until I had a decent margin between me and the car in front of me and I hit the brakes hard. At this point I was going around a very gentle curve in the road. To my surprise the car pull hard to the left. I keep my brake pressure steady and countersteer. It didn't skid at any time and I had to correct a couple times to get back under control and back down to a legal speed. Why did the car do that, it's never happen coming down from 90-100 before. What gives?
