on my GT, I installed 14 gr Dr Pulley sliders.
I noticed better acceleration on the bottom end. That is what I wanted. The performance difference is not mind blowing but, noticeable.
When you put it back together, torque to 69 ft-lb, run it a minute, the recheck torque to make sure you have not pinched your belt.
Never, never use Red Loctite on your variator nut. A small dab of Blue Loctite is ok.
It is not a complicated procedure. Just take your time and think carefully as you go.
Good luck.
