Global West Coil Springs
Global West highly recommends linear rate springs (also known as constant rate) over variable; not that variable rate springs are bad, but linear rate springs provide the best performance for muscle cars.

All Global West lowering springs generally lower the vehicle one-inch in the front and up to 1-1/4 inches in the rear depending on the option for your vehicle. They lower the vehicle to these specs because there is not enough suspension travel beyond one inch for street applications.
