You sir are clueless. First off drifting is not the fastest way around a road course. Second, you don't need an LSD for trailing throttle or throttle on over-steer. My track experience is limited to an SCCA comp license and I instruct for Chin Motorsports at tracks all over the Southeast, so I may be wrong. I live an hour from Sebring and spend quite a bit of time there. While it does have 2 very long straights, it has 17 corners. If you think throttle on over steer is the best way for a fast lap time, uhh, well I guess that figures. Now if the OP wants to drift, maybe he should just weld the gears in the rear together. Although that was not the question he asked.
I suggest you put me on your ignore list and we can both not be bothered by each others posts. Instructions are above. Don't you have another thread to pad your post count by adding nothing of value to? You have 6 fricken posts on this thread alone of which you've made it obvious you know nothing about.
