A metal wood golf club head is provided having a front face with an impact zone including a compliant area. Preferably, the compliant area is disposed in an upper portion of the front face. Preferably, a through-slit is provided in the front face to form the compliant area. The through-slit may be an elongated slot substantially parallel to a top of the front face and may include an elastomeric reinforcement. The compliant area creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. The compliant area upwardly shifts the coefficient of restitution to the geometric center of the face and thereby increases the carry distance of a golf ball hit off the club head.

A lift gate having a deformable section which allows the lift gate to deform rather than break during a low speed impact event. The lift gate has a deformable section located between an inner panel and an outer panel. The deformable section is able to deform during a low speed impact event against the outer panel, thereby preventing the inner panel from receiving any of the impact. This allows the inner panel to be significantly more rigid than the outer panel and the deformable section, and, therefore, provides the necessary structural support for the lift gate while withstanding collisions on the Impact Zone.
