This determines when your car switches to the next gear. Every car has them set by default, but the default setting isn’t always the best for the track you might be racing on. As always, you will need to tune for each race. It is advised you first familiarize yourself with the track (maybe do a practice run), and see if the track has longer stretches of straight driving, or more corners and turns- if the former, you want longer gear ratios. These give you slower acceleration, but higher top speeds. If it is the latter, you will want shorter ratios. Your top speed is capped, but you can accelerate far quicker now, and on a topsy turvy track with a lot of braking, that is actually exactly what you will need. You can also be boring, and just always go with balanced ratios

This is arguably the most important tuning you will do- the tyres you are racing with can single handedly determine your performance in a race, so you need to be sure you pick right. As stated in the previous section, know the track- select slick, all-terrain, ice, or wet tyres to ensure you have the right kind for the track conditions. As a general rule, if you are going to be racing on all paved roads, slicks are the best kinds of tyres- wet for wet tracks and ice for icy terrain. If it will be dry, but the track goes off road, then all terrain is your best bet. Finally, there are two variants for each tyre- soft (better handling, but degrade far more easily) and hard (last longer, but worse handling). Weigh the pros and cons, and go with the type that suits your play style better- or you could even switch between the variants within the same race, should you be so inclined.
