Spent the day getting the 4pt fitted. I got around to designing load plates to dodge my subframe connectors and had Sendcutsend laser cut them for $30 shipped, what a deal.

I went overkill with the welds, but better safe than sorry. Lap joints on the longest edge, diagonal under the main hoop, and underside, edge welds all around, and 2 plug welds (pic is before I finished them).

Bolted up, but I still need to finish making the sandwich plates [?] for the underside. I know most orgs want the lower plate to mimic the shape of the load plates and have all bolts run through, but I don't have that luxury. I can do a large plate for 2 bolts per side and then a separate large/thick fender washer for the 3rd. Not ideal, but I'm not cutting these Kenny Brown's out.

I also have to figure out where I wanna fab and mount sub brackets for the harnesses. The Corbeau passenger seat will be easy since it doesn't have a slider and I can mount a crossbar to the metal seat base. The driver will be more difficult since IDK about mounting it to the seat brackets the same way. If the slider breaks in an accident then my sub moves, seems sketchy. Maybe mount it to the floor somewhere?
