Mihai posted a topic in DIY Plans ONLYHello guys, I wanted to share with you my race rig project. When I started designing it I wanted to make one that you can easily adjust to sit in almost any race and road car position. So I stated by gathering information about the dimensions and the angle of different positions. I took 10 cars as models for my project. (4 F1 Cars: F1 2015, F1 198o's, F1 1970's, F1 1960's; 1 WRC car; 1 La Ferrari, 1 GT2; 2 Normal road cars: BMW M4, FIAT 500; and an ALFA 155 TI V6). I think that these examples are more than enough to accommodate almost any position. The rig is designed to fit only direct drive technology, because the motor needs to sit back and transmit through a cardan shaft the rotation to the steering. The pedals are lifted to the right height by a scissor jack. Both the upper part (that holds the motor, wheel, shifter, and monitor), and the pedal jack are movable through linear bearings. The seat is composed of 4 parts that move to accommodate almost any race and road car seat. The problem with having a one or two parts seat, when tilting it to obtain the correct position is that the back of the seat needs to bend to hold your back in the correct shape. So as a consequence the 4 parts are designed to fit correctly your body. All the adjustments of the rig are made with linear bearings, clamps, and screw type jack (pedals, and seat bottom height), so it is thought out to never get out of the rig to adjust it to the new position. I want to thank the Grabcad community for some of the 3D objects I use in my model. (the steering wheels, and human model) as well as Assetto Corsa for creating such realistic and beautiful detailed car interiors. I hope you like it. PS: I only managed to render the model for 2 positions: (F1 2015, and WRC Car)
