I was thinking it would be really cool if you could make the SBR4 Look like the Lamborghini and R8’s with the bumper deletes. I know you can get rid of the bumper, but 1. There’s no license plate, and 2. You can’t see the engine because of that thing. So basically what I’m thinking is we need something to enable us to be able to see the engine.
There really isn't an easy way to do this. You see, cars like the Lamborghini Aventador and the Audi R8 don't have trunks, only front trunks. The SBR has both a front and rear trunk. @Phym you would need to bypass the trunk to achieve this. As shown here with some minor editing to the body, the trunk would need to be deleted all together and not to mention all the bodywork to rework along with the jbeam probably.
actually, @ItsYourBoi made a sbr mod that gives you a cut body with the engine visible and a chassis mount wing link->https://www.beamng.com/resources/iyb-sbr.8278/
