Proper RX-7 Grounding Procedures

 

That's the exact procedure that I am going to use. I like it. thank you.

 

If any one could suggest on kind of stock to low performance spring and shock parts that would be great.

The car came with some lame coilovers. They do not even have a brand name on them. I feel as that my car my fall apart by going down the highway and going over those little bumps.

I am going to also by the suspension bushing kits and replace all those.

Any help would be greatly appreciated.

Thank you

 

KYB GR-2 shocks with Ground Control collars for ride height adjustment seems to work real nice for me. Not too stiff, not too soft. Good for everyday use.

 

I just found a what I think is a ground wire that the previous owner did not attatch.



It's a green and black stripe cable

 

Update:
-Had to put in a new neutral spring.
-oem shocks
-Want to make sure the ground for the ecu is good or re ground it. Does anyone know a good walk through on that?

 

Looking good man! I don't believe that the Gr/B (Green/Black) wire there is a ground, I was just looking at it two nights ago in my harness. It's an emissions part if I remember correctly, let me take a look.

 

ECU ground is located underneath the UIM. It most be removed to gain access. If the gasket plays nice and comes off easily, and you have a spare handy, this job can be done in an hour.

 

If you're going to remove the UIM, there are two ground wires from the EGI harness that are attached to the engine block. Also make sure the ground from the engine block(rear iron or housing, can't remember) is also attached to the firewall; it's a single spade connector on the firewall.
