One of the first things you need to strengthen if going above 500nmJust curious on this one has 500nm is substantially less than stock cars that run the ZF. My understanding ZF rate it at 600nm, so probably a level of 'safety' in that, maybe 50-100nm.

The stock torque is 450nm so less than 500. And the zf should be rated to a higher amount to handle it nicely.

Mine is stock height and when I spoke to King springs they said anything under SL height will do it. I have SSL leafs at home but have not put them in yet, don't know if I will either.

Went there Friday and the make a leaf that you can adjust in 3 heights, LOW,SUPERLOW,SUPERSUPERLOW. Anyone use or using the Pedders Leaf springs?
