Christian, I believe he may be talking about apex seal chatter at high rpms...but IIRC, that's an issue w/ 3-piece seals, not 2-piece.

I also believe a lot of the issues with going to high RPM's is harmonic vibration. Past 8500 RPM, you get a harmonic in the engine that can shake crap loose, like the tension bolts

.

Also, car makers have to design the components that the engine turns to work at high RPM. No use having a 10,000 RPM redline if the water pump is cavitating, the power steering pump is blowing up, etc.

On the RX-8, they fixed some of that. Power steering is electronic, so no belt there. Same for the air pump.

$2200 - DEAR GOD!

That's about right. Daryl Drummond is who does the work for Racing Beat. RB will only used new rotors so you figure $1000 for new rotors. The work and balancing by Daryl is $1200.
