Banned. I got OWNED!!!
I don't want to break my car, but lets be honest here. I bought the car to have fun in. I didn't buy it because I wanted to travel around the country. My max distance would be 60 miles. If it breaks, ahh well. I'd rather drive fun until it does.

The key to benefiting from the "High RPM mantinence" theory is hard driving to keep everything clean and operational. There is no further benefit beyond redline. But, engineers make redlines for a reason. One can argue both sides all day long about if redlineing will hurt a rotary. Rotaries like to be reved and driven hard, this is true. People who granny shift shouldn't own these cars.
That said.....
This is coming from an engineer....making buzzer sounding kamakazi runs on the limiter or spending any extended period of time in the red on any stock engine, rotary or otherwise (read stock internal components) is not a good idea. It provides no benefit and is causing un-necessary wear and risk to the powerplant.

The reason I like to push mine to the limits and hold it there is actually to see WHAT gives out.
That determines the order I upgrade parts in. 
If you don't want to replace parts, don't do what the people who made the car tell you not to do! DUH. But if you use common sense, rotaries aren't the same as pistons where revving too high on even a perfectly seated and unworn engine will cause internal engine damage because of friction levels... unless your rotary engine already has weak points, then it'll just smack those around until they're a major problem. But if it doesn't have problems, it won't make any new ones... the engine design is made to withstand, physically, more than the redline is set at.
What you should worry about is all your functional systems giving out... you push the car, and it's likely to break other parts... and if you're racing around and suddenly you lose fuel, coolant, air, spark... you're down until you fix/upgrade the part that gave... and any damage it did.
So use common sense, if you don't know enough about the car or aren't willing to deal with the consequences of breaking things, don't go pushing it around at the limits.

Very true. If you get your rocks off by beating up your car just to see "What breaks first" by all means auger that thing into redline on every shift! I prefer to drive the car hard and if something happens to fail upgrade it then. But, i am not one that is interested in driving with finding a week link as one of my main objectives.
Not that there is anything wrong with that.
