ls240z Posted February 5, 2015 Share Posted February 5, 2015 I removed my entire factory rail because it was in terrible shape and I wanted to clean up under it completely. Looking at the floor now, there is a large drop from one side of where the rail sits. The Bad Dog rails don't take this into account so now there is a large gap. I knew people have recommended to install over existing rails, but looking at this makes me think it's a requirement for the 280Z. The driver side looks like it will work fine because the floor is flat. My "solution" to the passenger side is to rosette/plug weld a length of angle along the floor along the trans tunnel side, acting like the "old, cut off rail", and then weld the new rail to it. Does that seem like the way to go about this? Or am I not looking at it correctly? I was desperately hoping my floor was ridiculously bent, but it is definitely supposed to be like that. Both Bad Dog rails are identical, so using the wrong side isn't the issue. Passenger side Driver side Where I currently stand Quote Link to comment Share on other sites More sharing options...
rturbo 930 Posted February 5, 2015 Share Posted February 5, 2015 Hmm. I don't know if this is really a good idea, but I wonder if you could just cut out that little channel and weld in something flat to even out the floors? Might be more work than it's worth though. And I imagine that channel adds a bit of strength to the floor. Quote Link to comment Share on other sites More sharing options...
ls240z Posted February 5, 2015 Author Share Posted February 5, 2015 (edited) Yeah, that would almost be a last resort for me. In all the threads I've read for installing these, I haven't seen this issue mentioned once. Edited February 5, 2015 by ls240z Quote Link to comment Share on other sites More sharing options...
johnc Posted February 5, 2015 Share Posted February 5, 2015 The 280 install requires some additional fab work as you have found out. Keep the BS rails straight and add in some sheet metal patches. No Ned for heavy angle iron, 12 ga sheet is plenty thick enough. Quote Link to comment Share on other sites More sharing options...
ls240z Posted February 5, 2015 Author Share Posted February 5, 2015 Thanks for the confirmation and mention of 12 ga John. When I said angle, I had planned on folding thinner sheet 90 degrees. 1/8" angle is the smallest I had found, and like you said, it's too thick.
