I have worked on many parts of my '15 T/A 2. No real surprises till today.
I purchased a seat lowering kit from a member on here, honest straight forward guy. He shipped me the kit (Snake Oyl) with all the parts. I pull the installation instructions off the manufactures website. I pull the seat from the car, removing the front bolts with my electric impact, slide the seat forward (remember this part) and loosen the nuts holding the rear mounts and the submarine belt mounting bar. I remove that oem tracks and install the lowering kit. At this point I have 35 to 40 minutes in the project.

I put the seat back in the car start the two front bolts the go the the rear. It is here that I discover that there is less than ZERO space to do almost any thing. It takes me about 20 minutes to get the sub bar in place and get the belts through the seat. To get the nut in place and tightened down it requires taping the nut to the socket attached to wobble adapter and a 3/8" extension and the patience of Mother Theresa, because you can no longer move the seat forward. You are do all this by feel zero room and contorted arm positions. At one point I called Snake Oyl to find out if I was correct on the install. When I told the rep that I had a sub bar he said "Oh they a difficult". I thought no sh*t. Three hours after I put the seat back in the car, I had the last two nuts installed and torqued.

If you are putting a seat lowering kit in your Gen V and have a six point harness I highly recommend have someone else do it and enjoy your day.
