Not trying to start an argument, and not trying to say I know everything but I have a stage 5 in my teg that made 450 whp and I did break one axle. It was due to an error on my part. I pulled into the beams and something happened to the guy in the other lane. They backed him out and told me to go. The next thing I saw the lights dropping and did not preload and ending up twisting the stock axle. First time ever I broke an axle(that was over 850 passes in my lifetime, lol). I use stock replacement axles and a open diff tranny. What breaks axles is driving (or lack of) technique usually. Way back when I was new to the game I did try the stock(new of course) pressure plate with the better than stock clultch disc and I found that the torque of a good tune up caused slippage, especially in higher gear. Of course I was making some decent power. The skinny is that <250 whp the stock pressure plate and stage 2 clutch will be fine, but for over that the extra holding power of a better pressure plate will help out. The stock pressure plate is easier on the axles because there is some slippage involved.
