Description
M7 Speed Stage 1 Chassis Reinforcement Kit
For 2002–2006 MINI Cooper & Cooper S Hatchback (R53) and 2005–2008 MINI Cooper & Cooper S Convertible (R52)
Maximize handling precision and cornering grip with the M7 Speed Stage 1 Chassis Reinforcement Kit, a money-saving bundle that combines two of M7’s most proven upgrades: the Strut Tower Brace (STB) and the Under Strut System (USS). Engineered, tested, and race-proven, this kit dramatically stiffens your MINI’s chassis so the suspension can perform at its full potential.
Key Features & Benefits
1. M7 Strut Tower Brace
-
Anti-Mushrooming Design: Exclusive ½-inch (13 mm) billet end plates sandwich the strut towers to prevent sheet-metal deformation and alignment issues.
-
Improved Steering Response: Cross brace increases torsional rigidity for sharper turn-in and reduced understeer.
-
Premium Construction: CNC-machined billet aluminum with a durable matte-black powder coat.
-
Easy Access & Fit: Clears stock/aftermarket intakes and ECUs; installs in about 20 minutes using factory hardware.
2. M7 Under Strut System (USS)
-
Triangulated Lower-Chassis Bracing: Three integrated extruded-aluminum sections reinforce the underside, dramatically improving stiffness and cornering balance.
-
Enhanced Rotation & Grip: Reduces understeer and allows the car to rotate into corners with confidence.
-
Durable Finish: Black-anodized aluminum resists corrosion and chipping; stainless hardware included.
Why Upgrade
A stiffer chassis keeps your tires in better contact with the road, allowing springs, shocks, and sway bars to work as intended. The result is maximum grip, faster response, and a true “go-kart” MINI feel—on canyon roads, racetracks, or your favorite on-ramps.
