Installation

• The front coilovers reuse the top hat from the stock strut/spring assembly, so you will need to disassemble the stock strut/spring assembly. You do not need a spring compressor for the disassembly, but a spring compressor makes it easier, as does an air impact wrench.
• Special tools needed: 17mm and 18mm deep sockets.
• With coilovers in place, distance from fender lip to center of wheel is about 14″ to 14.5″.
