Grounding Wires - Whats the verdict???

[JSPECFC3S]

I found mazdaspeed grounding wires for my FC for cheap. Who has a grounding system set up on their car? Is there a noticable difference in any aspect? Should I just save my money for better things?

Thanks

Normally I would agree with you, but RX7's have horible grounding systems from the factory and can actually benifit from this.

Teh Dirt can make you a grounding kit for pretty cheap.

RX7's can greatly benefit from new grounding wires. The wireing system is old and so are the grounds. Putting in some new ground wires along with cleaning the existing grounds will help.

Alot of FC's suffer from hesitation issues including the infamous 3800rpm hesitation. Putting in new grounds you will see better idle, better revving and all out better power. It should also take away the 3800rpm hesitation.

I did mine myself with some amplifier ground wires. I grounded the alternator, block, BAC, boost sensor both leading and trailing coils and ECU. After I did all of that it runs great! That was a few years ago. Just go to any car audio store and you can pick up wires and connectors for fairly cheap. I picked mine up at BOOMER Audio. The owner has a 3rd gen and is pretty cool.

I think I might redo it again. Same places just with thicker wires. I used 8 gauge an I want to change to 4 gauge wires.

I also recomend Teh Dirt for the grounding wires. I've seen his work and he does great craftmanship. All connections are saudered and the wires are cut to length.

Some cars benifit from them and some dont. It really depends on how dirty your grounds are. I would never spend any money on a grounding "kit". Just get a larger gauge electrical wire and make your own.
