The difference between the Smooth Gearing 43/13, 46-48/13, 43/13, and the Even Smoother 45/14, 47-49/13, 45/14 is noticeable, but quite tricky to explain, because it’s not quite straight forward. In general, the 43/13 gearing is ”punchier”, you need less run up to jumps in order to clear them, as the car accelerates harder, it’s better for small tight tracks. The even smoother, 45/14 gearing maintains momentum better, but doesn’t accelerate as fast from a low speed to clear a jump for example. So you could say, smooth gearing, 43/13 for tight technical tracks, and even smoother 45/14 for large, fast, sweeping ”euro style” tracks, but you would be mistaken, and here is why.
With the smooth gearing, 43/13, the car accelerates more, but not initially. Say you let off the throttle for a corner, the car slows more, so it is easier to control. Then you add just a little of throttle, and the car won’t do much, at first, you need to pull the trigger or push the stick more, you need to get deeper into the throttle before the car really starts accelerating, so you don’t need to be so careful and precise. Basically you can stay in control, and drive around the track with more throttle applied.
If you look at the video above, the sections where this was really evident was the right hand corners at 9 seconds and at 16 seconds, where after changing to this gearing I actually stopped because I wasn’t pulling the throttle enough. Also at 13 seconds, accelerating up to the jump I needed to apply more throttle, however, let’s say I made a mistake in the corner and lost all my speed, I could now easily clear the jump, where before I had to maintain my speed. Finally, the whole section starting at 25 seconds all the way to the back of the track, I had to use more throttle, so it felt like I was driving more punched to go fast.
43/13 Smooth Gearing: Basically you can stay in control, and drive around the track with more throttle applied.
With the even smoother 45/14 gearing, the car naturally carries more corner speed, so you have to make sure to brake enough to slow down. Also, when you then just barely touch the throttle, the car will go a lot more, so you can’t pull the trigger too much, you have to ”baby” it around corners more. You also need to maintain your momentum and flow around the track. It’s not as good if you point and shoot, then you are better off with the smooth gearing, 43/13. However, it has been our experience, that average racers prefer the even smoother gearing, and that is why we include it as stock with the LV kits. It takes less effort, and less throttle to go fast, and traction is very consistent.
If you look at the video above, it’s the opposite to before, the sections where the gearing was really evident was the right hand corners at 9 seconds and at 16 seconds, where with the even smoother gearing the car will maintain it’s speed, and you just barely touch the throttle. Also at 13 seconds, accelerating up to the jump I needed to make sure to maintain my speed to easily clear the jump. Finally, the whole section starting at 25 seconds all the way to the back of the track, I was barely using the throttle while cornering, and it was easier to flow around this section and maintain corner speed.
45/14 Even Smoother Gearing: It takes less effort, and less throttle to go fast, and traction is very consistent.
The gearing isn’t really a setup change that is used from track to track. Both produce the same lap times, it comes down to driver preference. It’s hard for me to even decide on which one I prefer. The past couple of years I have been racing with the even smoother gearing, now I am giving the smooth gearing a try.
