This pack contains everything you need to build a double arm front suspension with air bags and a rear suspension with differential and 4 links, in addition, rear disc brakes, functional shock absorbers and air bags, they come in 2 versions, inflated or deflated.There are also the necessary parts to assemble the compressors to inflate the air bags. The files, are in 1/12 scale, you can make conversions from this data to increase or reduce the scale. The reference photos that I attach are the photos of the models that I print for myself, everything was printed with an FDM printer. Obviously, the ideal would be to print these models with resin printers, the stl files are perfectly detailed to recreate the smallest details.Note. The chassis and the wheel and tires of the reference photos are not included.
