The process of tuning a Nissan R390 in Forza 5 can be broken down into two main sections, Setup and Suspension. Each of these sections is further divided into a number of subsections, which we will go over in more detail below.

What You’ll Need

In order to tune your Nissan R390 for Forza 5, you’ll need the following tools and materials:
-A copy of Forza 5
-A Nissan R390 GT1
-Access to a private garage in Forza 5
-Some knowledge of car tuning

If you don’t have a copy of Forza 5, you can still follow this guide, but you’ll need to substitute another racing game that allows you to tune cars.

The Nissan R390 in Forza 5

The Nissan R390 is a special car. It was designed and built to compete in the GT1 class of racing, which it did in the 1997 and 1998 seasons. In those two years, the R390 won six out of the eight races it entered, including the 24 Hours of Le Mans. The car’s success on the track led to its inclusion in Forza 5, where it’s available as a downloadable add-on.

If you want to get the most out of your R390 in Forza 5, you’ll need to tune it properly. Here are some tips on how to do just that.

First and foremost, you’ll need to decide what kind of driving you want to do with your R390. Are you going to be using it for drag racing? For circuit racing? For drifting? Once you know what you want to use your R390 for, you can start tuning it accordingly.

For drag racing, you’ll want to focus on increasing your car’s power and torque. You can do this by tuning your engine for high RPMs and by upgrading your turbos and intercoolers. You’ll also want to lower your car’s ride height and make sure that your tires are properly inflated. These tweaks will help you get off the line quickly and maintain high speeds down the drag strip.

If circuit racing is more your thing, then you’ll want to focus on improving your car’s handling. You can do this by upgrading your suspension and brakes and by making sure that your tires are properly inflated. You should also lower your car’s ride height so that it has less body roll through corners. Finally, make sure to tune your transmission so that it shifting gears quickly and smoothly.

And if drifting is what you’re after, then you’ll need to make sure that your car is properly set up for that as well. Start by making sure that your tires are properly inflated; under-inflated tires will make it harder for your car to drift. You should also upgrade your suspension so that it can handle the high wear and tear of drifting; coilovers are a good option here. And finally, make sure that your diff is properly tuned; a higher diff ratio will make it easier for your car to drift through corners.

How to Tune Your Nissan R390

The Nissan R390 is a car that first appears in Forza Motorsport 5. It is a GT1 class race car that was built by Nissan to compete in the 1997 24 Hours of Le Mans. The R390 was not successful in the race, but it did manage to set the fastest lap time.

The Nissan R390 can be tuned to perform well on a variety of tracks in Forza Motorsport 5. In this guide, we will show you how to tune your Nissan R393 for the following tracks:

-Nürburgring GP/DLC
-Circuit de Spa-Francorchamps

-Laguna Seca Raceway
-Road America

Adjusting the Suspension

One of the most important aspects of getting your Nissan R390 GT1 car to handle properly is adjusting the suspension. This process can be a little tricky, but with a few tips, you can get it dialed in perfectly.

The first thing you’ll want to do is check the spring rate. This is how stiff or soft the springs are and will have a big effect on how your car handles. You can adjust this by turning the knob on the shock absorber until you find the perfect setting.

Next, you’ll want to adjust the ride height. This will affect how much downforce your car has and will also influence how it handle. You can lower or raise the car by turning the knob on the suspension arm.

Finally, you’ll want to tweak the camber and toe settings. These two settings will affect how much tire contact your car has with the ground, and thus how much grip it has. You can adjust these by loosening or tightening the bolts on the suspension arms.

Tweaking the Brakes

Nissan’s R390 was a purpose-built GT1 racecar, and as such, it didn’t see a whole lot of development time before it was thrust onto the racing circuit. That being said, there are still a few things you can do to tune your R390 for Forza 5. In this article, we’ll take a look at tweaking the brakes.

The first thing you’ll want to do is adjust the front and rear brake bias. The default setting on the R390 is 70% front/30% rear, but you may want to experiment with different settings to see what works best for you. You can access the brake bias adjustment in the garage menu under “Setup.”

Next, you’ll want to take a look at the brake pads. The default pads on the R390 are decent, but if you’re looking for more stopping power, you might want to consider upgrading to a set of racing pads. You can find these in the “Upgrades” menu in the garage.

Finally, you’ll want to make sure that your tires are properly inflated. The R390 comes with fairly soft compound tires, so you’ll want to make sure that they’re inflated to the proper pressure. You can find tire pressure information in the “Specifications” menu under “Tires.”

Getting the Right Tires

One of the most important things you can do to improve your car’s performance is to make sure it has the right tires. In Forza 5, there are three main types of tires: performance, racing, and drag. You’ll want to make sure you’re using the right tires for the type of racing you’re doing.

Performance tires are designed for regular driving and provide a good balance of grip and comfort. Racing tires are designed for track use and offer more grip but may be less comfortable on the street. Drag tires are designed for straight-line acceleration and offer the most grip but may not be very comfortable on the street or in corners.

You can see what type of tires your car has by looking at the Forza 5 Tire Guide. To change your car’s tires, go to the “Setup” menu in Forza 5 and select “Tires.” From there, you can choose what type of tire you want and purchase them with in-game credits.

Fine-Tuning the Engine

There are a few things you can do to fine-tune the engine in your Nissan R390 for Forza 5. You’ll need to adjust the fuel mixture, ignition timing, and valve clearance to get the most out of your car.

Fuel mixture: The ideal fuel mixture for the R390 is 12.5:1. This can be achieved by using a higher octane fuel, such as 91 octane or higher.

Ignition timing: The ideal ignition timing for the R390 is 14 degrees BTDC. This can be adjusted by moving the spark plugs closer to or further away from the engine’s piston heads.

Valve clearance: The ideal valve clearance for the R390 is 0.004 inches (0.102 mm). This can be adjusted by using thicker or thinner shims under the valve lash caps.

Putting It All Together

After you have followed the steps in this guide, your Nissan R390 should be running optimally in Forza 5. This includes setting the correct tire pressure, adjusting the camber and toe angles, and fine-tuning the suspension to get the most out of your car. With these tweaks, you will be able to shave precious seconds off your lap times and will have a better chance of taking first place.


In conclusion, the process of tuning your Nissan R390 for Forza 5 is not difficult, but it does require some patience and attention to detail. By following the steps outlined in this article, you should be able to achieve the optimal driving experience with your R390.
