70561 Engine Compartment Battery Mounting Kit, Mk3/3.1/4 Roadster

This kit allows you to mount a group size 51 battery in the engine compartment of Mk3 and newer FFR Roadsters. The group size 51 battery was chosen because of its shape and weight. Its narrow shape facilitates installation low between the front X-member and the front transverse 4” round tube. It saves 11.5 lbs compared to the 40 lb Group 34 Mustang battery it replaces.

Benefits of this kit are:

• Improves handling performance because it lowers the center of gravity of the car by placing the battery only 3/4” above the bottom of the 4” tubes, and because it reduces polar moment of inertia (resistance to turning) since the battery is closer to the center of the car (location is between the axles).
• Saves 11.5 lbs weight by replacing the 40lb Group 34 Mustang battery.
• Lowers cost and reduces build time by eliminating the need for remote battery terminals and a battery cut-off switch (easy under-hood battery access).
• Eliminates the need to replace the FFR supplied 4ga positive cable with a heavier 2 gauge positive cable due to shorter positive battery cable.
• Frees up valuable trunk space

The tray, and all mounting hardware are made of stainless steel. You gotta get this!
Notes: Batteries not included.
