Robot Craftsman Mustang V5 GTD Widebody — S550 Arches Fixed
Stock S550 arches look soft next to modern power. The Robot Craftsman Mustang V5 GTD widebody fixes that with SEMA-grade presence that stays streetable — wider front arches, side skirts, rear arches, bumper/diffuser, and the GTD-inspired silhouette that finally matches the car.
Built for S550.1 and S550.2
The kit covers Ford Mustang S550.1 and S550.2. For S550.2 (2018–2020), S650-style headlights and brackets are supplied (adapter included; custom wiring may be required). Note: after the GTR/GTD wing is installed the rear trunk cannot fully open — plan the wing option before you commit.

Wheel fitment notes (flush 20")
Running 20" wheels flush to the new arches usually means trimming the inner corner of the side skirt for full lock, and cutting the rear arches for suspension travel with wider rubber. Example red-car 2-piece setup from the PDP: F 20×10J ET-55 (285/30) · R 20×11.5J ET-29 (315/30).
Pairing / cross-sell: forged wheels that fill the arch
A V5 GTD widebody only looks finished when the wheel fills the new arch. Two CarGym lanes that work for Mustang builds:
BC Forged HB04 — modular 2-piece forged aluminum with step lip / deep concave. Custom width and offset so you can target that flush 20" red-car style without guessing blank sizes.
BBS LM — classic Le Mans 2-piece forged windows if you want motorsport silhouette behind the GTD arches (confirm Mustang PCD/offset with us before ordering).
