Do-It-Yourself (D-I-Y) S13 Chassis Subframe Swap Kit

If you have been researching alternative methods to significantly enhance the handling performance of your 1984-89 Nissan 300ZX & Turbo, you will likely learn many enthusiasts have opted to replace the stock Z31 rear sub-frame with one from an S13 or S14 (1989-1998 Nissan 240SX).

Replacing the stock sub-frame allows you to take advantage of the inherent adjustment available to the S-Chassis multi-link suspension, along with significantly higher pool of aftermarket products and support.

This kit from PastPower Innovations will provide you the fabrication-specific parts you will require in order to cut, weld, and assist with installing your S-Chassis rear subframe. This kit was originally developed by a member at the Z31Performance Forums, and is commonly referred to as the “ShamWow/MikeG Swap Kit”. Other attempts at providing a swap kit have been tried, but do not come with the breadth of parts and proven usage as the original MikeG Kit.

The Z31/S-Chassis Subframe Swap Kit from PPI includes:

• Two (2) Subframe Mounting Studs
• Two (2) Subframe Mounting C-Channels
• One (1) Subframe Stud Retention Bar
• Two (2) Subframe Bushing Cups
• Two (2) Subframe Bushing Relocation Brackets
• Four (4) Gusset Plates for Subframe Bushing Relocation
