ARVOU S2000 HKS GT2 SUPERCHARGER 2025

ARVOU S2000 HKS GT2 SUPERCHARGER (ver.2025) mod is now live!
This particular ARVOU S2000 is a time attack machine that achieved an impressive 53.173-second lap at Tsukuba Circuit earlier this year (January 2025).


Sorry for the long silence — it’s been hard to find time to work on mods lately. I’m finally getting back into it, and I really appreciate your patience and continued support.

WIP: Upcoming Car & Track Mods

The 3D models for these cars are mostly complete or close to final, but the physics/driving behavior, and texture work still require significant time and effort. These mods are not yet ready for release, but I’m sharing the current status for those interested in the progress.

I’m doing my best to make time for development whenever possible—thank you for your interest and support.

Toyota GT86 LW Revolution 2.1L (ZN6)

Back in 2019, this GT86 recorded an incredible lap time of 1:00.196 at Tsukuba Circuit (Course 2000)—still the fastest ever for an NA, non-swapped GT86.

In 2023, the same car was updated with a 2.4L GR86 engine and managed to break the 1-minute barrier, but this 2.1L ZN6 version remains a legendary benchmark for the original platform. 🏁🔥

⚠️ Note: This mod is based on a very old model created years ago, so the model quality is quite low.
