[QUOTE=aaronng;1817240]Sounds like the springs and/or damper are too soft. Similar problem to the old 2003 Corollas.

My parents had a corolla and I always thought that it was the 1.8ltr just too much grunt for the size of the car, boy was it punchy, so much that mum didn't like driving it cause so punchy, touchy.....take off was amazing launched like a rocket from take off...very similar feeling to the mazda6 but I felt as if it was due to weight not so much springs/dampeners I could be wrong. Another reason I say it's weight is that I took it through a thourogh testing....under heavy braking springs/dampeners where quiet good, whole car should of dipped/lowered at the front but didn't.

And you are spot on about the motor reving to the stage that I too thought better take it easy cause sounds as if it would throw a rod or piston or something, lol.
