Not directly related to the "gtrr", but thought I'd post this here anyway..
Made a rig simulating F3-seating for my friend.. just got it done It's not 100% ready, but the main structure is there. Wooden parts need to shaped (some of them) and painted.
It's very comfy even if it doesn't necessarily look like it and extremely sturdy. The seat is my friends actual urethane foam seat from a couple of years ago when he drove the national F3 championships here in Finland.
