Do you really think the deflectors on the LCA add that much performance?? i coulda sworn that the arms were the same across the Perf pack and the non perf pack so i could just 3d print some anyway. either way without the deflector and LCA just the ducting would prolly be plenty for like autocross which is what I do.
I would say its pretty vital but agree maybe there are other alternatives. I have yet to look but maybe there is an S550 variant we can use. Either way we would not force you to purchase them.
Ill 100% give this a shot whenever I get the time off of school and such, will definitely contact you about that free shipping you mentioned earlier lol as its almost the price of all the parts combined. Also while ford doesn't sell the OEM deflectors separately, but steeda does sell a deflector kit that should fit as the s550 and s650 have what looks like identical LCAs so ill buy that and give it a shot too.
What the GT PP's & DH come with are better than nothing, but IMO, if you plan on tracking the car hard and tracking a lot, consider finding a good Mod Shop in your local and have them do something like the Kenny Brown Kit (attached)or similar. You want as much air hitting the discs as possible and a hose with duct inlets and cooling ducts is about the best you can get.
