Diminishing Radious Turn?
I was reading a breakdown on a Canyon road and came across this term: Diminishing Radious Turn.
Can anyone explain what this is and what the implications are for driving it?

From my experience it is more commonly known as a decreasing radius turn. But that's semantic. Anyway, what it basically means is that the turn tightens as you travel further through the arc. Two other types are (1) increasing radius -- the turn become less tight as you travel the arc--and (2) constant radius -- the curve would form a perfect circle if carried for 360 degrees.
A decreasing radius turn can be tricky to negotiate as the first part of the curve allows a high entry speed. However, as the curve becomes tighter you probably won't be able to maintain that higher entry speed. An inexperienced driver may brake or drop the throttle when they realize that the turn is tightening beyond their ability to control the car at the entry speed. When this happens in an S2000, the result will likely be a nasty spin.

This may be total BS, but the way I understand it is: turns in hiways/roads/tracks are usually engineered using a radius, i.e. if it were a full circle it would be perfectly round, with a radius. The smaller the radius, the tighter the turn, with appropriate speed recommendations when the turn would require lowering your speed to safely make the turn, if less than the posted limit. I've read that pro racers can just about set the steering wheel going into a turn, and not have to adjust the steeriing until they roll out of the turn. A decreasing radius turn is one which starts at one "radius," but gets tighter (decreasing radius) as the turn progresses.

Palomar Mountain in San Diego seems to have alot of dimishing radious turns as well- I have gotten in trouble coming in too hot, but thankfully, I have been able to maintain.
Does the 50/50 weight distribution on the S help reduce throttle lift spin problems?
