Here’s something for those looking for some free online & offline racing fun. Speedsims.net offers two sports car mods for NASCAR Heat that relive the look and feel of the old SCGT days and work without needing any commercial game.
While one mod lets you race various Group C cars, the other mod includes GT2-like sports cars to be raced online or offline. The mods require either NASCAR Heat or the Heat Essentials Package which can be downloaded completely for free. More information and all downloads can be found on Speedsims.net
