Description
Ford Performance GT350R Brake Upgrade Kit — Mustang (2015–2023)
This is the same brake system fitted as standard on the Shelby GT350R — now available as a genuine Ford Performance upgrade for your 5.0L GT or 2.3L EcoBoost Mustang. Your factory brakes simply aren’t built to handle repeated track sessions on a hot day; this kit gives you an authentic OEM overhaul with GT350R-spec components, sourced as a complete package rather than hunted down piece by piece.
A genuinely massive braking upgrade
This kit centres on six-piston Brembo front calipers and four-piston Brembo rear calipers, finished in the signature gloss red of the GT350R (black also available). They clamp down on 15.5″ cross-drilled front rotors and 14.9″ cross-drilled rear rotors — a substantial jump in both swept area and bite over the factory setup, giving you genuinely shorter stopping distances and far greater resistance to brake fade during sustained hard use. New brake pads, caliper adaptors, and all necessary hardware are included for a complete installation.
Half shafts and knuckles included
This isn’t just a caliper and rotor swap. Ford Performance includes genuine GT350R-spec half shafts, engineered to support significantly more power than the stock items, along with GT350R knuckles pre-fitted with spherical bearings — adding real strength to your independent rear suspension alongside the braking upgrade.
Kit includes:
- GT350R front calipers, rotors, and brake pads
- Front caliper adaptors
- GT350R rear calipers, rotors, and brake pads
- GT350R parking brake assemblies
- Rear GT350R knuckle and hub assemblies
- GT350R axle assemblies
- All required hardware
- Detailed fitting instructions
Caliper colour options: Red or Black
Important — wheel clearance: Stock 2015–2021 Mustang, EcoBoost, and Mustang GT wheels in 17″, 18″, 19″ (including non-Performance Pack and Performance Pack) and 20″ sizes will not clear the GT350R calipers. Please contact us before ordering if you’re unsure whether your current wheels are compatible.

FAQ Section
Will my current wheels fit over this brake kit?
Most likely not. Stock 2015–2021 Mustang, EcoBoost, and Mustang GT wheels in 17″, 18″, 19″, and 20″ sizes will not clear the GT350R calipers. Contact us before ordering to confirm compatibility with your specific wheels.
Is this a genuine Ford Performance kit, or an aftermarket brake upgrade?
It’s a genuine Ford Performance kit, using authentic GT350R-spec components — the same brake system fitted as standard on the Shelby GT350R.
What caliper colours are available?
This kit is available in Red or Black, matching the gloss red finish used on the factory GT350R, or a stealthier black option.
