Well, I regularly shift my MP3 around 4k+.
I also have been autocrossing about every other weekend since february, and I run second gear to redline a couple times a weekend doing that. Chances are my engine won't last as long, but if you stay under 3000, you might as well have bought a Honda Insight and left the performance car you have for someone who enjoys driving it.
I'm not trying to be rude, but realistically, these cars were made to be driven. Run it up! The car will be fine. If you can't enjoy it, there's no need having it. Its just an object. It's replacable. Life isn't. You only get one life. Live it up!
