Description

The STILLEN Adjustable Rear Sway Bar Kit is engineered to significantly enhance the handling dynamics of your Infiniti Q50 or Q60. By increasing rear sway bar stiffness by 37-70% over stock, this kit directly addresses body roll, leading to improved cornering performance and a more balanced feel when navigating curves. This enhanced control can also contribute to better straight-line stability, as noted by a user who experienced transformed handling in their Q50 AWD. Constructed from high-strength aircraft-grade steel, the sway bar is built for maximum torsional strength and long-term durability. It features a powder-coated finish to protect against corrosion and maintain a clean appearance. The 3-way adjustability allows drivers to fine-tune the suspension stiffness to their specific driving preferences, whether for spirited canyon driving or track use. This kit is designed to fit both RWD and AWD models of the 2014-2024 Infiniti Q50 and the 2017-2022 Infiniti Q60. It comes complete with necessary hardware and installation instructions to facilitate a straightforward installation process, though some users have noted minor challenges, such as fitting the new bar around existing aftermarket exhaust systems.
