Also, Pedders "scraggs" their coil springs which basically means they compress them to a coil bound state. Since this essentially pre-sets the spring you get a part that has increased durability and performance.
All of Pedders coil springs are load tested to give you the most accurate ride height possible. The higher end springs have a height tolerance of +/- 2mm while every spring falls into the +/- 6mm range which is consistent with the OE springs on your vehicle.
The Pedders brand is a staple of the automotive scene in Australia and they have earned a reputation as a trusted manufacturer of suspension parts. Whether it's replacing a broken coil spring or lowering your favorite track car, Pedders has an excellent selection of springs to fit your needs.
