Front Nose Modification

Can you guys please post some pictures of how you modified your front nose wheel liners. The car I purchased had the front splitter mounted to the front nose and I know some have done that and that is an option with just using the front support bars. Currently I have it removed and I was going to mount it like most everyone has using the front radiator support and then using the support bars on the outside and inside, but that’s honestly not all that much support and if you mount it correctly to the front nose with some rivnuts and the front two bars I would think you would get good support. I know chassis mount is always best for downforce but in all honesty, the front street splitter is pretty flimsy. It’s not like some splitters that you can stand on top. I had a GEN4 ACR, which obviously generates a lot of downforce and it was mounted to the front under body plastics with maybe a few bolts that went into the chassis and it protruded 6 or more inches). It had just two front support bars and I know many high-performance cars are mounted this way. So to get to my questions, I am debating how I want to mount the splitter but another thing that has come up is my inner fender liners in front nose is completely sealed if I mount the splitter to the front nose. There are no cut outs at all. So where the either front brake duct vents or where some have put fog lights is basically a dead end into a dead space so I’m just questioning should I just cut out the circles where it appears that some have used to access the front lights or I guess another option is to run bright brake ducting from the front nose vents back and make an opening. Also, is there an option to also mount the rear bars , but I don’t see how you could mount the rear bars and be able to remove the splitter with the front nose. I hope this makes sense. I’m posting a picture of my front nose. I’m no aerodynamic expert, but if those two front ducts allow air to come into a dead space that can’t be good so it has to get out somewhere so I’m just trying to figure out where to either cut holes or different options.

Definitely the right question to ask! The first time I had mine over 150mph (inner fenders installed and stock splitter mounts, literally all 4 of the splitter mount brackets broke AND a few sections of the inner fenders separated their bonds due to all the air pressure in that area. In hindsight it was pretty stupid of me to not block off those ducts before I did that run. Regarding solution:
  1. If you're going to track the car, install a 3" silicone flex duct from that air duct, through the fender liner to the brake disc center. If not I'd just block it off somehow since there's no other purpose for it that I can think of.
  2. I added two extra latches that connect the hood to the splitter at the corners and make it much more solid. If you're not going to track the car or take it at high speeds, that's probably not necessary.

Thanks Howard. Now double supports on the sides makes much more sense. Also can you show me how you have your inner fenders cut on your nose?? Also I assume the brake inlet on the nose abuts the inlet cone on the splitter? Where did you get that piece??

Mine are completely homemade, not the RCR options. I'll find some pictures and post them. Yes, the inlet "female" cones cover the nose outlets "male" when the nose is on the car.
