What this mod does

The Radical SR3 XXR is the 2023 generation of the Radical SR3, the small British prototype that the brand bills as the world’s most popular race car. This Assetto Corsa version was made by UnitedRacingDesign (URD) with official data provided by Radical Motorsport, and it’s published on OverTake from the brand’s own account.

What it promises

According to the mod page, the XXR brings more power and precision than the previous SR3, so you can go faster, harder and for longer. The page gives no further specs: to learn about the real car, it links to Radical’s website.

Requirements

The mod page doesn’t list them, but several reviews agree: one user cites the URD website, which asks for Custom Shaders Patch 0.1.79, and others fixed crashes by updating to that version. They also warn about a DLC error when loading the collider, which you fix by installing the Ready To Race Pack on Steam.

What users say

The 3D model and sound get a lot of praise. The physics are demanding: some describe the rear end as hard to predict. The average rating, 4.39, is dragged down by people who couldn’t get it to load.

Tips

Update CSP and check that you own the Ready To Race Pack before installing it. Take fast corners gently until you get to know the car.
