Good news is the Professional Awesome mounts are easily modified to fit our cars, and would bolt to your splitter easily. Check out in my thread for details. I hit plenty of stuff with my splitter and mounts stayed true.

Agreed, that would be my plan of attack if I was @bronco100 . Save the splitter blade, mount it with the PA mounts and supports, and move on. Doubtful that 777 is going to give you any meaningful resolution or re-engineer their mounts in a reasonable time frame.

I don't want to compete in CAM, and if I did I would prefer utilizing aero to get more grip rather than running a wider tire.
Not sure why you appear to be against wider tires. It's well documented here that all the fastest Mustangs (regardless of powerplant) are running 305 square at a minimum. If it's a classing thing, that's perfectly understandable but rules willing, wider is seemingly always better. I can't think of one instance where an S550 mustang, pro or amateur, has intentionally gone below a 305.

@Fair on here has said that he has never gone slower by going wider with tires.

No disrespect meant; just trying to help. Love the build!

I'm certainly not against it, although in most classes that I compete in, a wider tire would put me in classes where I'm not competitive. At the moment I'm typically competing with sports cars that are stock or lightly modified, such as GR86/BRZ, Miatas, WRX/STI, Honda S2000. I have put down faster lap times than plenty of cars with wider tires, including Mustang GT's, Dodge Chargers, Camaros, etc.

The law of diminishing returns certainly seems to apply as well. I'd surely save tenths with a wider tire, but wider tires and wheels are not only more expensive, but cost unsprung and rotational weight.

For my next event I am limited to a 285 wide setup. After that I may look into wider options.

Took 2nd place in Enthusiast class in Global Time Attack. I only had time to install the one hood vent because for some reason our hoods are so difficult to cut through. Perhaps there's a particular type of grinder wheel I should have used, but the ones I had which said they were for cutting metal, did not do that very well.

To fit the regulations of the class, I went with the Yokohama Advan Apex V601 265/25/18 - a 280TW tire that was not as wide and not as grippy as I am used to, so there was a fair bit of sliding involved, see here (
)

Also new for this event was a Garett intercooler. Worked very well to keep charge air temps down. You'll also notice some custom 3d printed block off plates on the bumper side grill areas. It's a Mach 1 bumper, so I imagine on an actual Mach 1, those side grilles allow airflow to oil/trans coolers, but in my case I don't have such coolers, so it helps decrease drag if I can block it off entirely.
