the Dark Horse has a unique diffuser not only for the diff cooler, but also for bigger exhaust tips. the resonator is a different part number, but i don't know about the internal parts of it or the mufflers. the exhaust tips are also lower than the GT's, so to look right you would need to buy...
there is something holding it up: your dealer. your order code is 19 so Ford isn't going to pick it up, and that might be because your dealer has no allocations for a Dark Horse, or they really have no intention on giving your order to Ford
it does affect it, my DH had a higher priority than a co-worker's did, and i got mine first. his came in probably a week ago. this guy's order doesn't have handling package, painted stripes, or carbon fiber wheels, so there's really nothing stopping it
call me crazy, but given this is an RTR Spec 2 with serial number 2, i would argue the price is a little more justified. it's a 401A with brembos, but i think that they should waive the $1350 for the now removed optional 20" wheels
hopefully getting some custom vinyl work done soon-ish (after 11/25/23), more than just what i shared was planned. not gonna spoil it but it's gonna be awesome
put some wide tires on. i get exactly 0 wheelspin unless i launch with RPMs above 1500 or so. you should also use drag strip mode instead of sport for that kind of thing
