Re: 500rwhp is not a leafsprings's best friend.
Nice...That was a good vid-- a side view of the pinion angle change would be pretty cool also. Even with my lowly 335hp, the driveline noise changes tell me when the axle is moving the pinion from quasi-happy to pissed off. I was surprised at how much the pinion moved up. My pinion angle is already above the driveline and seeing that affirms that its needs to be lower.
