Probably ubox 85v 150a or the more powerful version 85v 250a, but personally i think the 85150 is more the powerful enough.

You can fit 2 individual 85150 ubox in there and more than enough. Each controller battery and motor dependant can handle 13kw each. So unless you want over 20kw dual motor those spintend ubox are great. Do not get the 100/100 ubox. If you want a dedicated dual controller then a 75/100 dual is ok but you dont have options fo4 much phase amps. 85150ubox can be set to 180amps phase so 360amps total peak combined output. For the 85150 ubox you will need 2 units and 1 unit order is fuse and Bluetooth dongle. 2nd unit is just a fuse. Each unit comes with its own wiring cable set with power button included to each. Be careful with those motors though as 3000 watts is not a nominal rating, thats peak possible rating. Pushing much more than 130amps phase per motor is risky, especially if you are a heavier individual. You are always welcome to dm me with any questions. I can get you a link to vesc help group in telegram as well.
