5 stars because WIP, would be 4 stars for a 1.0 version. IMO 3 things to improve: add vibration (FFB) when driving on the kerbs; better sand textures and better concrete walls textures. Overall, very good job so far!
Not sure what wheel you use but with my T300 the kerbs vibrate the wheel just fine. As far as textures many are indeed still a WIP and won't be addressed likely until 0.9 or 1.0.
I'd give this six stars if I could. It's arguably the best mod track there is. And it's better than quite a few of the Kunos originals. Thank you for creating and sharing this.
