Will It Clear? How to Buy Wheels for Your Performance Pack (Brembo) Mustang
Share
You own a 2015–2023 Mustang GT Performance Pack (or a Mach 1).
You absolutely love those beautiful, massive 6-piston Brembo brakes up front. You order a set of deep-dish wheels that look amazing online. They arrive, you jack up the car, and you go to bolt them on... CLUNK.
The back of the wheel spokes hit the face of the brake caliper before the wheel even touches the hub.
This is the nightmare scenario for S550 owners. It is known as the "Brembo Curse."
Because the Performance Pack calipers are so incredibly wide, they severely limit your aftermarket wheel choices. You cannot just buy any generic wheel with the correct 5x114.3 bolt pattern. You need wheels engineered with "High Pad Clearance."
In this guide, we break down exactly what spoke curvature means, list the top premium wheel styles from HRE FlowForm and Forgestar that are guaranteed to clear your big brakes without using dangerous spacers, and explain the perfect offsets required to run massive 305mm tires in the rear.

Frequently Asked Questions (Wheels)
Will these wheels fit my Performance Pack (Brembo) GT?
Only if they have a "High Pad" clearance profile.
The 6-piston Brembo calipers on the PP1, PP2, and Mach 1 are incredibly wide. They require a wheel with specific "spoke curvature" to arch over the face of the caliper.
- Safe Bet: The Forgestar F14 and HRE FlowForm series are industry standards specifically engineered to clear these brakes.
- Risky: Traditional "Deep Dish" wheels with a flat spoke face will almost never clear a 6-piston Brembo without a massive wheel spacer.
What is the widest tire I can fit on the rear of my S550?
A 305mm tire is the absolute safe maximum.
On a standard-body S550 (EcoBoost or GT) with the correct ~ET50 offset:
- 10-inch wide wheel: Fits a 285/35R19 or 285/35R20 perfectly.
-
11-inch wide wheel: Fits a 305/35R19 or 305/30R20 perfectly.
(Note: While some owners squeeze a 315mm tire onto the rear, it will often rub the inner fender liner if the car is lowered. A 305 is the safe, proven maximum width for a flush fit).
Do I need Hub Centric Rings?
Usually, yes.
Most premium aftermarket wheels (like Forgestar or Vorsteiner) are manufactured with a larger center bore (e.g., 73mm) to fit multiple vehicles. The Mustang hub is exactly 70.5mm. To ensure the wheel centers itself perfectly and prevents high-speed vibrations, you must install a 73mm-to-70.5mm polycarbonate or aluminum Hub Centric Ring before mounting the wheel.
