I literally floor my e36 325i multiple times per day and I now have over 320,000 miles on it. As long as you have the right amount of the correct oil in the engine, I really don't think high rpm's have that much affect on a BMW 6 cylinder engine. Now, some rental-car special, i.e. Malibu, Fusion, Altima, etc may not handle it as well.
