With the install of my JRE spindles on my 2008 Nytro MTX, I have a positive camber which appears to be out by a half an inch (12.7mm). This is just an eyeball guesstimate. I know with the initial 2008 ball joint mod, the instructions called for a 2.5mm removal of metal to bring the spindle to a slight negative camber for improved handling.

What is your opinion on removing around 12mm?

I did this to my 08 nytro mtx now but i removed 7mm(9/32 inch) on each side. It is a new sled to drive now. Before i could not have the skis in the narrowest position because the sled became unstable then, now i have it on the narrowest and i can drive hard on trail and i can sidehill almost like burandt:)
