In Gran Turismo Sport, there are generally two ways to go about getting a faster car. The first is to buy a new car and the other is to tune your ride.
How do you go about this? We've got a step-by-step guide for you right here!
How to tune
Go to your garage and select a car that you wish to tune. From there, you'll enter the car's submenu, and you'll have to scroll to the car settings menu, which is symbolised by a spanner.
You'll then be taken to the tuning screen, where you can look at tyres, brakes, traction control settings and much more. The key stats of the car are located on the left-hand side of the screen. So, you can easily see how much you've improved your ride.
"Quick Tune" is a very handy feature for those that don't want to dive deep into the stats of the car. Quick Tune, like the rest of the areas of the car, can be upgraded by pressing "x" when the cursor is on "Level up".
The best way to upgrade the car is to attach which new parts you think will improve its performance, then practice in time trial with the new settings. If you like it, keep it, if not, take it off and try something else.
You should also note that you can save certain settings for a car for future reference. GT Sport allows up to 10 per vehicle, so you can be prepared for any racing scenario.
Why tune?
You might be wondering why tuning is a good idea? After all, in the long run, it can be easier to buy a new car rather than continuously upgrading the same ride. However, that's quite a short-sighted and expensive way to go about.
Furthermore, some tournaments specify certain car manufacturers or manufacturers from a certain region to compete. Performance is often capped, but sometimes it's about the brand of the car. Plus, you can tune a car to at or near the ceiling of performance levels allowed for the cup to give you the best possible chance of winning.
Take this from DriftingCulture on YouTube as an example. He tunes a Nissan GTR from 445 bhp to almost 1,000!

You have to be careful, though, as faster on paper doesn't always translate to the track. That Nissan is built to have under 500 bhp, so the brakes, suspension, tyres etc... aren't configured for a 1,000 bhp vehicle.
Upgrading the engine will require massive upgrades to the rest of the car to be balanced. Sometimes, you can't truly balance the ride after a massive tuning session like this and you'll struggle around high-downforce circuits. That situation is even worse in the wet too, particularly for rear-wheel drive cars.
