-prefix-free lets you use only unprefixed CSS properties everywhere. It works behind the scenes, adding the current browser’s prefix to any CSS code, only when it’s needed.
“[-prefix-free is] fantastic, top-notch work! Thank you for creating and sharing it.”
— Eric Meyer

Properties as well in Firefox < 3.6.Check this page’s stylesheet ;-)
You can also visit the Test Drive page, type in any code you want and check out how it would get prefixed for the current browser.
Just include prefixfree.js anywhere in your page. It is recommended to put it right after the stylesheets, to minimize FOUC
That’s it, you’re done!
The target browser support is IE9+, Opera 10+, Firefox 3.5+, Safari 4+ and Chrome on desktop and Mobile Safari, Android browser, Chrome and Opera Mobile on mobile.
If it doesn’t work in any of those, it’s a bug so please report it. Just before you do, please make sure that it’s not because the browser doesn’t support a CSS3 feature at all, even with a prefix.
In older browsers like IE8, nothing will break, just properties won’t get prefixed. Which wouldn’t be useful anyway as IE8 doesn’t support much CSS3 ;)
Test the prefixing that -prefix-free would do for this browser, by writing some CSS below:
You might ask: Why not just play Assetto Corsa Competizione or iRacing?
Clean geometries that eliminate jagged edges on car bodies and wings.
This turns a "good" DTM mod into a that feels unlike any other GTR2 content—closer to rFactor 2 or Assetto Corsa Competizione 's DTM DLC, but running on GTR2's legendary 2006 engine.
The original modding sites (NoGripRacing) are largely dead. Here is the current map:
The "Extra Quality" designation guarantees overhauled texture files. Standard definitions are replaced with 4K resolution liveries, realistic tire wall branding, and highly detailed brake disc textures that glow dynamically under heavy deceleration. 3. Advanced Physics and Tire Realism gtr2 dtm mod extra quality
Nearly two decades after its release, SimBin’s GTR2 – FIA GT Racing Game remains the gold standard for PC racing simulation, not due to its official content, but because of its unparalleled modding ecosystem. Among the myriad of third-party conversions, the Deutsche Tourenwagen Masters (DTM) modifications—specifically those bearing the unofficial “Extra Quality” (EQ) moniker—represent a technical and artistic apex. This paper examines the historical context of GTR2 modding, deconstructs the specific engineering philosophies that define “Extra Quality” DTM mods (focusing on physics, sound, and visual fidelity), and argues that these community-driven projects have inadvertently preserved a lost era of touring car racing more authentically than many modern commercial titles.
: High-quality mods often integrate custom physics profiles, such as those found in the Get Real Physics Mod , which address straight-line stability and tire traction issues.
The screaming V8 sounds of the mid-2000s DTM cars are iconic. Superior mods feature immersive, realistic audio that changes based on camera angle.
Even with extra quality mods, GTR2 is finicky. Here are fixes: You might ask: Why not just play Assetto
This article explores the best high-quality DTM mods available, how to enhance them, and why they continue to thrive in 2026. 1. Top "Extra Quality" DTM Mods for GTR2
If you need help troubleshooting common issues like ?
Unlike modern AI that often sticks rigidly to a racing line or drives like a train, GTR2's AI defends aggressively, makes calculated mistakes, and flashes their headlights to pressure you into errors.
High-quality mods feature detailed, high-polygon car models for cars like the Audi A4, Mercedes C-Klasse, and BMW M3/M4. Physics must capture the immense downforce and specific tire characteristics of DTM cars. The original modding sites (NoGripRacing) are largely dead
By using extra quality mods in GTR2, players can enjoy a more immersive and realistic racing experience. Benefits include:
Audio is crucial for spatial awareness and immersion. This mod utilizes multi-layered, high-fidelity engine samples recorded from real-world historic motorsport events. You will hear the distinct high-pitched scream of the vintage inline-fours, the deep rumble of modern 4.0-liter naturally aspirated V8s, and the violent pop of unburnt fuel hitting hot exhaust pipes on downshifts. How to Install the Mod
So, what does "extra quality" mean in the context of GTR2 DTM modding? It refers to the attention to detail and realism that modders bring to their creations. This can include:
Which of DTM cars you are trying to find or install?
Extra code on top of -prefix-free that makes it more flexible, integrates it with different APIs etc
Originally a part of -prefix-free, it’s now a separate plugin. It makes -prefix-free take care of:
<link> and <style> added to the document afterwardsstyle attribute added to the document afterwardsstyle attribute changes through setAttribute() (except in Webkit)element.style.transform = 'rotate(10deg)';
style attribute modifications will not work in Webkitelement.style.transform = 'rotate(5deg)';will not work in Chrome (reading will)
Get the Dynamic DOM plugin now:
A tiny plugin (I didn’t even bother minifying it as it’s so small) that lets you set/get unprefixed CSS properties through jQuery's .css method.
Get the jQuery plugin now:
A static polyfill for the new vw, vh, vmin, vmax units.
Enables rudimentary CSS variables support.
