Building the Sub Frame mounts

Getting the factory RL frame mounts to work

The sub frame is coming together.  After taking 50 measurements and double and triple checking all of them I came to a point where I was happy with where the motor was sitting.  It is low, but necessary to not have to cut a hole in the hood.  From my measurements it looks like I will be losing 2” of droop from what the stock RL suspension travel had, but I don’t think this will be a problem.  The factory motor mounts off of the RL where able to be grafted over onto the frame of the civic.  I have to space it out correctly, which I did using 1x6 steel.  I boxed in the steel and for now have just tack welded the mounts in place.

You can see on this pic below the centered sub frame. I used a plunge bob and center the subframe for 4 seperate places that all came out to be centered perfectly.

I then started in on measuring up the rear mounts.  I was hoping I would be able to use the mounts off of the RL again for the rear, but no luck.  The firewall curvature along with the height that I need to be at is just too far off what the RL mounts can provide.  I will have to build these mounts completely from scratch.  One nice thing I have going for me is that the mounts line up underneath of where the old sub frame was bolted into the frame.  What I am thinking at this point then is building the rear mounts to bolt into the frame so that they are removable.   I have ordered some 2.5x2.5 inch steel and a coupler nut that is 2.125”, which SHOULD fit perfectly in the box of the steel and be welded securely so that I can drive the bolt all the way up threw the mount.  We will see how this goes and I will be sure to take pics of the progress on that.
