I want to put my stillen grounding kit from my coupe onto my sedan but i cant seem to find the first mounting point. On the coupe there is a bolt right below the wheel well but there is almost nothing on the sedan. Everything has rubber spacers which wont work, and the strut mounting screws are too big. Any ideas?

 

This individual did a great job of compiling some information on this site. Look at the picture in step 6. See the bolt next to what looks like "OR" stamped into the metal? They have a bolt. Now, look at that stamp on your vehicle. You do not. However, you do look like you have a grommet or cap covering a bolt hole. Pop that thing off there, and throw a bolt in there. Voila!

 

^ +1, remove the grommet.

I took a quick pix of my set up for you - however I have the 2012 sedan - I had an existing bolt in the same place and removed it to use the bolt that was provided by Stillen to secure it accordingly, then used some zip ties to hold the wire in place.

 

I've been considering doing this.

Does it actually do anything?

Ahhh ok i see what your saying, ill give it a try and let you guys know! Thanks man

 

Does anyone know if disconnecting the battery is mandatory to notice the difference? meaning does resetting the ECU help you notice it. I connected all the points then the ground to the battery last, took it for a spin but i hardly can tell a different. I noticed a big difference on my coupe when i did it so i might just disconnect the battery and see.
