Slider: Every time the vehicle mechanics change all the new ones, the old ones are replaced by the sliders. As long as you buy a heart and only change it, if you install it well, there should be no difference with the new slider. It takes 300 faster to change the slider. Is it better to put 300 dollars on the number of rotations to buy a good number of rotations? (Note that when buying a slider, you should buy those without letters, and look at the thickness of the copper inside the slider.)
