Product Details
Looking for a front sway bar for your 2009-2013 Mini Cooper John Cooper Works (R56)? The Whiteline Heavy Duty 26mm Front Sway Bar is made for it. The listing names the John Cooper Works trim. The kit contains 1 sway bar and 2 bushings. Order it as part number BMF73. Position: front. Whiteline's note for this fit: Suits R55/R56/R57 models.
A sway bar is a torsion spring that links the left and right wheels. When the body leans, the bar twists and resists, which keeps the car flatter and spreads load more evenly across the tires. In general, a stiffer front bar reduces roll and helps the nose stay planted, with a tendency toward understeer if it is overdone. The bar is adjustable, so the stiffness can be changed to suit the car and the road.
Expect a moderate job of about 3 hours. Plan on a wheel alignment afterward. Other Whiteline parts we list for the Cooper: Adjustable Rear Sway Bar Link, Front Strut Tower Brace Quick Release Kit, and Heavy Duty Blade Adjustable 20mm Rear Sway Bar.
Features
- Bushing compound: The elastomer formulation is chosen to shrug off oil, grease, ozone, and the elements.
- Finish: A powder coated finish resists corrosion and wear.
- Install guide: Whiteline packs an install guide with it.
- Roll control: Built to reduce body roll and sway in corners.
- Lateral locks: DIY lateral locks stop the bar from shifting sideways under cornering loads.
- Bushing material: Made of polyurethane, which resists deflection better than soft rubber.
