What does PSI mean? The Past, Present and Future [September 2026]

 

After the mod was publicly posted, we received several questions regarding what it does, the changes that were made, the additions, and its overall focus. In here, we’re going to talk about every feature ProStreet International brings and what it means for the people involved with it.

What does PSI mean?

ProStreet International is a mod project that seeks to enhance vanilla Need for Speed: ProStreet with things such as new, period-correct customization and an overhauled handling model, with plans to explore and improve other areas of the game in the future.

It all started with a few of us playing ProStreet online with Radmin, as it was a game we all enjoyed. During one of our sessions, the idea came up "What if ProStreet got an enhancement?" Inspired by works such as underground2.net, we started working on it. The beginnings were a bit rocky, and one could say a bit messy, but we quickly managed to get ourselves on track and attract a lot of talented people who understood our vision. It slowly grew to become what it is today. If it wasn't for all the people who contributed along the way, the mod wouldn't have become a reality or reached the state it is in today.

Our name is a reference to Best Motoring/Hot Version International, as the team is made up of car enthusiasts from various backgrounds, countries, and specialties, which enriches the knowledge and perspective behind the mod and car culture representation. This mod is dedicated to car enthusiasts who seek an authentic ProStreet experience and want to take it to the next level.

Customization

The customization has several new additions to the existing cars in the game. The aim is to add content, so there will be no replacements made or considered. As of now, we focus on creating original designs, but we also welcome donations and offer credits to the authors of them. Real life body kits and parts are also welcome.

(DISCLAIMER: The staff reserves the right to determine whether or not your donation is approved for the mod.)

Cars that as of 28/09/2026 got a new bodykit available to the public: 

• 1+ Acura NSX (NA2) 
• 1+ Aston Martin DB9 
• 1+ BMW M3 (E92) 
• 1+ Chevrolet Corvette Z06 (C6) 
• 1+ Chevrolet Camaro SS '67 
• 1+ Infiniti G35 (V35) 
• 1+ Mazda RX7 (FD) 
• 1+ Mazda RX8 
• 1+ Nissan Skyline GT-R V-Spec (R34) 
• 1+ Nissan 350Z (Z33) 
• 1+ Nissan 240SX (S13) 
• 1+ Porsche 911 Turbo (997.1) 
• 1+ Toyota Supra (A80)

A lot of the kits have clear inspirations from real-life kits. For example, this C6 Z06 features visible Geiger, LOMA, and C6.R inspired parts that are mixed together and redesigned, taking creative liberties to fit them into a single kit while giving it a different character. With this design process, it isn't just a 1:1 parts mashup or a "direct ripoff" when the individual parts are separated and compared to their real-life counterparts. So, even if you were to get a Geiger kit, you can still find this kit, and most specifically the front bumper as a separate entity and as its own design.

Another recent example is this EJ6 body kit, which looks very close to C-West, but if you look closer, you start to notice the differences with the front bumper. For instance, the bottom of the lip is different, being flat and similar to the one from Charge Speed. Another difference is that the grille section remains the same as the OEM one rather than using the C-West design.

Wheels

Wheels are an important part of customization, they can completely change the look of a car, even if it keeps its stock body. We decided to take an unorthodox route, so, instead of focusing on adding "new" wheels, we chose to remodel the wheels from the vanilla game first. Factually, they don't look very good and don't do justice to their real-life counterparts.

Wheels that as of 28/09/2026 got a new remodel available to the public: 

• 5zigen Hyper 5ZR 
• 5zigen FN01R-C 
• ADR Design GT-Sport 
• American Racing Torq Thrust II 
• BBS LM 
• Enkei NT03+M 
• HRE C20 
• Racinghart CP-F Tune R 
• Racinghart CR 2P 
• TSW Rocket 5 
• Rays Volk Racing TE37 
• Rays Volk Racing CE28N 
• Rays Volk Racing GT-P 
• Rays Volk Racing GT-S 
• Rays Volk Racing GT-7 
• Weld Racing Legacy 
• Weld Racing Alumastar

Upcoming wheels for the next update:

• Enkei WRC Tarmac EVO
• OZ Superleggera III
• Work Emotion CR KAI
• Work VS KF

Add-on wheels are being considered, and in fact, we already have an add-on wheel made and reserved. However, for now, our focus is on getting the remodeled vanilla wheels finished.

Some of our wheels offer a higher level of customization thanks to AutoSculpt. Here, we will show some examples:

BBS LM:

Rays Volk Racing CE28N:

Weld Racing Alumastar:

Work Emotion CR KAI:

Another note to comment, is that our wheels with autosculpt you can spec them in more accurate specs to their in real-life counterpart:

The extra options we offer are a great addition that gives your build more personality and provides greater control over the look you want to achieve, as you can see.

Livery Editor

The next update will feature an update in the livery editor, adding new decals from the previous games, mainly from the likes of Modern Image and Art Factory Graphics. New sponsor decals are also being worked on to be added in a future update, adding several new shops across the globe.

Handling

The handling is one of the weaker aspects of the vanilla game, and for a game focused on race days, we had the mission of overhauling it to make it feel much more proper. Our goal is to make the cars feel like proper representations of what they are known for when driving them, prioritizing the feeling of the cars over raw data, since ProStreet doesn't have an advanced simulation system that allows us to implement some of that data.
Our test track was Autopolis, a Japanese track known for Super GT, Super Formula (formerly known as "Formula Nippon"), Super Taikyu, the at the time World Sportscar Championship, D1GP, and the All Japan Road Race Championship. The track broke ground in 1989 and opened to the public in 1990, with hopes of eventually hosting F1... which never happened after a series of questionable and sketchy events. It is known for its significant elevation changes, which can exceed 50 m (160 ft), as well as its thin air and low atmospheric pressure due to being around 800–820 meters (2,600–2,690 ft) above sea level. It also features a 902m (2,959 ft) long straight, followed by a heavy braking zone into the first corner, making it one of the key areas for overtaking. It is the most professional racing facility available in ProStreet, making it the perfect playground for testing.

The handling model is in constant evolution and continues to change, but the current handling available to the public rewards an aggressive driving style and make players to attack corners at higher speeds rather than taking them more slowly. It also offers an accidental bonus that has made AI racers more competent and willing to take riskier racing lines. Some cars, such as the GT-Rs, might struggle a bit on low-speed tracks like Ebisu, Mondello Park, or the Willow Springs Horse Thief Mile layout, but this is being addressed for the next handling update which will transform (again) the whole game.

Our member Bacura did a time attack around Sonoma Raceway (formerly known as "Infineon Raceway")
 in an Acura NSX (NA2) that helps to showcase the handling:

Reshade

Our good friend Katriot worked on ReShade presets for PSI that can help improve your photography and showcase your builds even better. There are two versions: the Main Preset and Real Long Exposure. The "Main Preset" helps make the cars pop, while "Real Long Exposure" works especially well for rolling shots.

Common questions

Will the mod feature add-on cars?

Not at the moment, but the idea hasn't been ruled out.

Will the mod feature add-on wheels?

As previously stated, yes. However, this will come at some point after we finish the vanilla wheels.

Will the mod add more race tracks?

Unfortunately, we don't carry the technology and tools yet.

What period is the mod set in?

2008.

Can I play this mod with other mods that enhance the AI difficulty?

Yes, but it is not ideal, as some things might break.

Can I play this mod with other customization mods?

Yes, but be careful, because many mods won't be compatible with PSI specifically those that involve replacing textures, models, or changes to the handling. Those will completely override many of PSI's changes.

Can I mix it with other handling mods?

No, it will break completely.

Can I play it in another language other than English?

No, some scripts will break.

Will it be uploaded to NFSMods.xyz and Nexus Mods?

Yes, once the mod feels "finished".
