Can anybody comment on the ZZP and Intense Input Shafts? Car is around 500 whp turbo 2006 Monte Carlo SS v8. Car will be run on slicks...
I see that ZZP offers an upgraded shaft 300M that handles more power, but intense only offers the one or a GM Racing piece that is $$$$. I was pretty much set on the 300M option from ZZP, but they are out of stock for a few weeks.
Anybody know of either units breaking?
