ZGT Cars is part of the Reaction Research, Inc, family, and produces the “ZGT” rebody kit for the 1996-2002 BMW Z3 Roadsters. Because of the excellent design of the Z3 chassis, all major ZGT panels bolt on using mostly factory hardware. All factory safety features (including bumpers) are retained. The Z3 Roadster chassis were designed from the start to be convertibles, and later models are equipped with a semi-automatic convertible top. Power windows and power mirrors are also options.
