Torque springs are quite important when it comes to adjusting your transmission. They put pressure on the rear pulley and influence clutch performance. They have to be replaced with a harder spring as soon as the belt is starting to slip and the engine is starting to underperform in spite of using lighter weights. If you're going for a harder spring, you'll have to readjust your variator.
