Ramps<\/h2>\n\n\n\n<p>How to identify them? Let\u2019s take an example: 45\/85.<\/p>\n\n\n\n<p>The first number indicates the acceleration phase on which the self-locking device acts. The second number indicates the braking phase. The lower the number in acceleration (ex: 30), the faster the ramp is considered.<\/p>\n\n\n\n<p>Therefore, you will feel an excellent traction behavior, but with more sudden and faster reactions during acceleration, while in the case of low grip they can cause handling problems.<\/p>\n\n\n\n<p>A ramp 45 will therefore have a slower and more gradual acceleration delivery, facilitating handling at the expense of traction.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. Clutchdiscs<\/h2>\n\n\n\n<p>On R5 (Rally2) cars, different solutions are used depending on the car.Some of these use the same number of clutches for both differentials.<\/p>\n\n\n\n<p>Usually, the more clutches there are, the greater the traction will be at the expense of ease of use. A common use is called in jargon in the various solutions 4+4\/6+6, and in some cases 8+8 for XTrac transmissions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. Self-locking preload<\/h2>\n\n\n\n<p>A good calibration of the self-locking preload will be crucial in defining the handling of the car \u2013 from understeer to neutral to oversteer \u2013 depending on the driver\u2019s needs.<\/p>\n\n\n\n<p>In some cases (and cars) the preloads, as well as the clutches, are the same between the front differential and the rear differential.<\/p>\n\n\n\n<p>In other cases (for example long wheelbase cars) it is preferable to have a preload of the rear differential, designed to help the car run more smoothly where the road is trickier.&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today, modern rally cars mainly have two differentials, namely front and rear self-locking differential.
