Ground Wire Gauge Recommendation, 87 Brat

Recommended Posts

Folks,

I am going to be redoing the grounds on my Brat soon and was thinking about 8 and/or 10 gauge cable. Streetwires OFC power cables (both gauges) are quite cheap at EBay. Will also make custom battery cables from 1/0 Gauge Streetwires OFC power cable. I appreciate any recommendations.

Regards,

For the most part, a Subaru doesn't run enough current to warrant wires of that size. Really all you need are clean connections. Having said that, I'm running 4-ga between the battery and the engine block, the block and the body and the battery to the body. I've got 4-ga running from the battery to the starter and 8-ga to the fusible link cluster. My wire size choices were made predominantly by the fact that 4- and 8-ga wire was what I had on hand when I needed to do all that re-wiring.

 

Realistically, you could get away with 12-ga grounds all the way around without a problem. You just have to make sure that the connections are clean and tight.
