GT Street Series 1.0.0

Welcome to the GT Street Series (GTSS) — a global, manufacturer-backed GT3 championship fought exclusively on street circuits in the world’s greatest cities. Sixteen fast-paced sprint events, top-tier works drivers, and premium sponsors aim to make GTSS the most spectacular global GT series from day one.
You step into the role of the young but highly talented rookie Maximilian Schnell, who surprisingly secured a seat with Audi Sport. Are you ready for the challenge — and can you become the first GTSS Champion?

What this mod includes

• At least 4 GTSS-style skins for each of 14 GT3 cars (so you can easily customize your own championship)
• Track skins in GTSS style for 16 street circuits
• Additional grid slots for all tracks with fewer than 28 starting positions
• The GTSS Season 2025 as a fully prepared Content Manager championship
• Content Manager presets for all 16 weekend sessions if you prefer to run them individually

This custom championship requires Content Manager, Custom Shaders Patch (0.2.7 or newer) and the following paid mods:

• Race Sim Studio: GT-M Phase 1 Pack (£10.49)
• Race Sim Studio: GT-M Phase 2 Pack (£13.99)
• LP Design: CC8 GT3 Final Version1 (6,50 $)

Please follow the instructions step by step and in the correct order, otherwise the mod will not work as intended. For more detailed instructions, please check the readme.pdf
