To replace the controller's stock PCB easily with Brook's lineup of Fighting Boards for better performance as well as expanding functionality (universal) for other modern or retro systems.  Also to replace a non-functional PCB.  Arcade controller manufacturers sometimes to do not offer replacement pcbs. 

Why would I need the Optimus Mod Kit and not just hook up the Brook Fighting Board directly?

For custom builds where you have control over all of the functionality, hooking up a Brook Fighting Board is easy and a kit, such as the Optimus Mod Kit is not required.  For commercial arcade controllers where you want to keep the look and functionality of the various features, the Optimus Mod Kit assists with this by using our custom breakout board(s) and cable kits to allow you to mod by simply plugging in same and replacing pcbs.  There are no soldering or cutting wires involved.   What this means for you is saving time, up to 80% less modding time as everything is provided and the instructions on how to install the board is laid out.

In a Optimus Mod Kit, you get the breakout pcb and accessories (some additional accessories may be required if you don't already have them, such as the 20-pin harness for this mod) to connect to Brook Universal Fighting Board (or one of their other boards)

What is the advantage then for an Optimus Mod with Brook UFB (or dual mod w/ Brook Retro Board)?  

Speed, performance, universal system compatibility.  Brook Fighting Boards have been known to have the lowest latency on the market.  In addition, the UFB provides additional support for other systems, such as the Xbox 360/One/X/Switch/WIIU and of course, PC Support

A New Generation

Before there was OPTIMUS MODs, we had partnered up with Jasens Customs for a series of EZ MOD Kits for a variety of arcade controllers.  To this day, these kits work well and we still offer them.  The EZ MOD architecture was made for the latest technology at the time and the Brook Retro Board was not available at the time and some of the functions on certain controllers were not fully optimized

What is an OPTIMUS MOD?

OPTIMUS MODs are our solution to the easiest possible pcb modding using the Brook Fighting Board PCB's which are considered the fastest on the market. This is the next generation of easy modding kits.  Each OPTIMUS MOD is system specific, which means it's optimized to fit, work and provide the shortest modding time possible for each controller

Mod Like a Pro in a short period of time

To integrate a Brook Fighting Board PCB into commercial arcade sticks is a challenge, even for the most seasoned modders.  This requires not only an understanding of the physical and signal directional properties, but also the time requirement of making custom cables and planning board placement.   What the Optimus accomplishes is cutting down your modding time from 5 hours or more down to under an hour
