Save your money, these cars come equipped with a toggling regulator controlled by the IPDM that switches it's charging load based off on the needed events.
There is a battery current sensor located in the negative battery cable that monitors charge/discharge and helps this toggling of voltage.

With that being said, an upgrade would be a new negative battery cable and route it like factory.

The other two grounds located in the timing cover are pretty thick themselves and can handle the job required.

You can test the resistance of your ground wires which there shouldn't be any. If there is then a replacement would help a bit.

Sometimes these ground kits bypass the sensor and tell the ECM to slow down the engagement of the regulator which will cause lower voltages and for some battery drains.

Do you mean a new negative battery cable, same gauge thickness as OEM, without the IPDM sensor?

I meant the small extra dongle on the positive part of the battery, not IPDM

A new wire with sensor (oem)
a new thicker wire passed through the sensor.
