    As I have looked into the Hirochi SBR4, I saw a ton of problems for the SBR4's cooling system, from the radiator to the intercoolers, in doubt, see Hirochi SBR4 | Page 23 | BeamNG for reference.

    So you know what, I have decided to take matters into my own hands regarding those issues.

    Intercoolers:

    Rearranged the intercoolers right on top of the engine bay for ease of maintenance (reconnected the intercooler nodes to the engine instead of the body), and installed pipes to cool the engine bay connecting from the body's side vents. Also added catalytic converter 3D models as well since the original does not have catalytic converter models.

    Radiator and others:

    Added a vented hood (that has a triangle producing downforce) right on top of the radiator so that it can be cooled. I know it is very hard without rearranging the radiator's position and the piping as well which I minimized involving those by redesigning the hood instead. I also added an alternate rear bumper with a large center vent for a cuter look. The seats have been thinned (but still thick enough that they can be ventilated seats) so that there is more leg room for the front driver and passenger. There are a new set of 19x8 front and 19x11 rear sport 2R tires for more grip.

    Next steps (DONE in 1.1):
    - Add tail ducts for rear bumper (between engine bay and rear bumper vent)
    - Enlarge cooling pipes between body vents and engine
    - Add vented rear diffuser for more exit cooling at the engine bay

      Tbh the vanilla SBR's cooling is very abnormal, the air has no way out be it intercoolers or radiator.
