Some other things to note:
The bearings in this piece are very nice. Sealed spherical bearings all over the place.
The forward mount support plates are pathetic. Rest assured, we are already developing some new ones....that are thicker, with tighter than Ford tolerances. These plates should help drastically with subframe fore/aft shifting...and will be great for those not looking for much NVH increase. Of course, they will be very good for those looking for maximized IRS rigidity too.
Camber - haven't seen a way to adjust it. We are already looking into making an adjustable relocated upper arm. It is very complex, though.
Toe - the toe rods are actually pretty damn good. We have already built some prototypes though, that are very strong...and lighter. Yes, it is possible! They also allow for more adjustment. The OEM design features an eccentric bolt...but I prefer using a solid mount over the eccentric with a truly adjustable arm/rod, personally. On the other IRS Platforms we support, we have seen too much inconsistency with eccentrics when really being put to use.
The spindles, lower arms, etc (all the aluminum) are very nice. Engineered nicely, and unfortunately....there won't be any reason for the aftermarket to make these pieces (other than what I mention below about wheels)
The brakes, are great. The clearance is VERY good...as the outer portion of the calipers only protrude from the mating surface of the rotor by 5/8" - someone was thinking about the drag racers when making these, kinda.
The combination of the larger rear brakes, the spindles, and the RLCA make it impossible to run a wheel smaller than 17" for the drag racers. It is not like the old days, when I could spend 6 hours in my shop finely grinding away here and there, to get my 15" wheels to fit my '04 Cobra IRS and Brakes...
There is a REALLY good chance that we will be offering a 15" wheel conversion kit, like we do for the 2010+ Camaros. The question is, will the Ford market accept and pay $4000 for it, like the GM market? LOL
Shocks and springs.....the shocks seem to have a ton of compression stiffness. The springs seem to be very stiff as well. Makes sense. I hope to have some spring data (rates) as well as shock dynos very soon to share. We always get this data for engineering our BMR brand components, as every company should. And of course, I will definitely share anything I find out. For example, the front Sway Bar on the 2015 GT is 433lb/in. Even though it is substantially smaller in diameter than the 11-14 cars, it is only 3lb/in away from the 11+ 436lb/in..
The shock and spring design could be better in my opinion, in terms of placement / and aftermarket. As in, it is going to be much more difficult offering a coilover kit for this car, from what I can see. If you place a C/O kit where the shock is, you will have Wheel/Tire clearance issues....and if you run it where the spring is, well, you will only have a 5" tall C/O Kit. ha!
Fingers are tired. Wife bought this new keyboard and it feels like pressing down on a solid floor.
