Explore performance cars in interactive 3D and see every modification before committing to a build. Experiment with paint finishes, wheels, ride height, aero parts, exhausts and studio environments, with each change appearing instantly on the vehicle.
3DTUNNERS is an interactive project for exploring the visual direction of a performance-car build before parts, paint and stance choices are committed. It is useful for enthusiasts comparing ideas, designers testing colour and proportion, and anyone who wants a clearer reference than a folder of unrelated product photos. Choose a vehicle from the garage, open it in the Build Studio, then work through the paint, wheels, suspension, aero, exhaust and lighting options that are available for that model.
Interactive 3D makes those decisions easier to read together. A wheel design can be judged against the full body shape, a paint finish can be rotated through highlights, and a lower stance can be inspected from the front, side and rear rather than from one edited image. Environments also show how the same colour and material respond when the reflections around the car change.
The platform is actively being developed, so model detail and customisation coverage vary across the current vehicle list. 3DTUNNERS is built for visualisation and creative experimentation; it does not confirm mechanical compatibility, safe clearance or road legality. Real parts and installations should always be checked against the vehicle specifications and reviewed by qualified professionals.
The workflow is deliberately simple: choose a base car, make one change at a time, and use the live viewport to understand how those choices work together.
Browse the garage and select one of the performance vehicles currently available. Each car opens as an interactive model, but the level of model-specific detail and the compatible visual options can differ while support is being refined.
Work through the available paint, wheel, suspension, aero, exhaust, lighting and environment controls. Changes are applied as you make them, so you can test a restrained road-car setup and a more dramatic concept without starting over.
Rotate and zoom around the vehicle while the material and geometry updates remain visible. Change the environment to check how reflections, colour and surface finish respond in a bright showroom, a darker workshop or an outdoor scene.
Compare combinations, reset the configuration when an idea is not working, and keep adjusting until the visual direction feels coherent. The Save control stores a build in the current browser so it can be revisited from the garage on that device.
Paint is treated as a material, not a flat colour swatch. Metallic and non-metallic finishes use different metalness, roughness and clearcoat settings, while reflections help describe gloss, carbon-fibre and metal surfaces. The same finish can look brighter, darker or more reflective as the lighting changes, so comparing environments is an important part of judging a colour.
Supported paint, wheel, suspension, aero, exhaust and lighting changes appear in the viewport without reloading the page. That makes it practical to compare combinations and undo an idea quickly. Initial model loading can still take longer on complex vehicles or less powerful devices, and the experience works best in an up-to-date browser with hardware-accelerated WebGL.
A showroom, night scene or outdoor setting does more than change the backdrop: it changes the reflections across the body and can alter how a paint colour is perceived. Switching scenes helps reveal highlights, roughness and contrast that one light setup may hide. These environments are creative visualisation tools, not exact simulations of real roads, weather or calibrated studio lighting.
A convincing build comes from seeing the major choices together, not from choosing each part in isolation. Paint affects how the body lines read, wheel design changes the visual weight around the arches, and ride height changes the space between those wheels and the body. The Build Studio keeps those controls close to the viewport so you can make a change, rotate the car, and decide whether it supports the overall direction.
The available controls include colour and supported material finishes, wheel designs and rim colours, suspension type, ride height, camber, selected spoilers or wings, exhaust finishes, tint, lighting and environments. Coverage varies by vehicle because imported models do not all expose the same geometry or material structure. The tool does not calculate bolt patterns, wheel offset, tyre deformation, suspension travel or aerodynamic performance. Use it to form a visual brief, then confirm real dimensions and parts with the relevant manufacturer or a qualified installer.
Colour · finish · material response
Try gloss and solid-style colours alongside metallic, matte, satin, pearl, candy, chrome and carbon finishes where supported. Roughness, metalness and clearcoat change the way each surface responds as you move between lighting environments.
Design · size · finish
Compare the wheel designs and rim colours available in the studio, then adjust the supported visual size. Wheel behaviour can differ between vehicle models, and an on-screen result should never be treated as confirmation of brake, suspension or arch clearance.
Spoilers · wings · supported body parts
Preview supported ducktails, lip spoilers, GT wings and swan-neck designs together with the body treatment available for the selected model. Some imported vehicles have more limited geometry support, so unavailable or unfinished parts are not presented as real fitment products.
Ride height · camber
Adjust suspension type, visual ride height and negative camber where the model supports those transforms. A dedicated wheel-offset control is being developed and is not currently available. Real suspension travel, tyre clearance, alignment and local road rules must be checked separately.
Car enthusiasts often have to picture a finished build from disconnected references. A wheel listing shows the wheel by itself, a paint sample is photographed under unknown lighting, and an aero part may only be shown on a different colour or setup. Most manufacturer configurators are designed around factory colours and trim, so they do not answer the question I kept coming back to: how will several modification ideas look when they are combined on one car?
I created 3DTUNNERS to make that early visual experiment easier. The project brings together my interest in cars with my work in web development, real-time graphics and interactive interfaces. Next.js handles the site, while Three.js and WebGL make it possible to move around a vehicle and update its materials and supported parts directly in the browser.
It is still a hands-on, actively developed project. Some cars are more complete than others, and each new model introduces different challenges in geometry, materials and performance. I would rather explain those limits than present the viewport as an engineering tool. The aim is to give people a useful place to explore a direction, learn what affects the look, and arrive at a clearer reference for the next stage of a build.
Learn more about the projectThink of 3DTUNNERS as a visual planning and entertainment tool. It can help you decide that a darker wheel suits a bright paint finish, or that a particular ride height changes the attitude of the car in the way you wanted. It cannot guarantee that the same combination will physically fit, drive safely or comply with local rules.
Wheel and brake clearance can vary with width, offset, tyre choice and the exact vehicle. Suspension changes can alter alignment, available travel, handling and tyre wear. Aero and exhaust previews do not certify a part, predict performance or replace manufacturer instructions. Real installations should be measured and checked by qualified professionals who can inspect the actual car and the components being used.
Vehicle specifications, model files and the options shown in the Build Studio may change as the project develops. 3DTUNNERS is independent and is not affiliated with vehicle manufacturers unless that is explicitly stated. If something in the current catalogue looks incomplete, the contact page is the best place to report it.
These guides explain the visual and technical ideas behind common choices in the configurator, along with the checks that still need to happen on a real vehicle.
Wheel fitment is a relationship between width, diameter, offset, tyres, brakes and suspension—not a single number. This guide explains what to inspect in a visual concept and what still needs to be measured on the real car.

3DTUNNERS is a browser-based vehicle visualisation project built with Next.js, Three.js and WebGL. It lets you choose a supported performance car and explore combinations of paint, wheels, stance, aero, exhaust and lighting in an interactive viewport. The project is intended for creative experimentation and early visual planning rather than measurements, mechanical design or engineering approval.
