PRODUCT DETAILS
This is the Whiteline Front and Rear Grip Series Stage 1 Kit. This kit includes all of the essential components that will drastically improve your handling for high-performance driving conditions. Not only do you get a set of front and rear sway bars, you also get a complete set of lowering springs to lower the center of gravity in your vehicle. When combined, you get better handling for track days or for high-performance driving conditions to provide the driver with better feedback and confidence to push their vehicle beyond the factory limits.
Here is what is included in the kit.
The kit starts out with the Whiteline Front and Rear Sway Bar Kit that has a 26mm 2-point adjustable front sway bar, and a 22mm rear sway bar that is 3-point adjustable. These sway bars will reduce body roll as well as lateral loads which will spread evenly across the tires which will result with improved grip and better performance on or off the track. The sway bars will include premium sway bar links, premium bushings, as well as locks and hardware to make them ready for installation.
The performance springs will lower your vehicle to provide a better lower center of gravity and will complement the sway bars in terms of handling to bring better balance and more driver confidence under high-speed corners.
In conclusion, Whiteline delivers a kit that will drastically improve the handling dynamics of your vehicle. If you enjoy spirited driving, or the occasional weekend autocross or track day then the Whiteline Grip Series will certainly suit your car for such conditions. This is a great modification that will improve your driving experience, and you will certainly love how your car handles.
