In-between messing with the electrical stuff I’ve started looking at the front sway bar as I really need to have one and it’s probably the last major thing to do. With the motor/oil pan setup I have, there’s no way to install a bar behind the cross member unless it hangs below the transmission and or steering rack. I guess I could do it but it’d get hung up on something sooner or later.
That said, I’ve started looking into moving it in front of the cross member. There is some room (4” or so) in between the back of the oil pan sump and the cross member. The only real issue I see at this point is the lack of space between the frame and the OEM lower control arm. With the stock set up it’d be difficult to put any kind of arm on a splined Speedway type bar to make it to the end links. I’ve been looking at the Megan Racing Lower Control Arms and it looks like they might provide the space to make this work. I really don’t want to have to deal with all of the adjustability these provide as I suspect it’ll make alignment way more difficult, but I need the room.
You can see in my crude drawing below how it might work. I suspect the location of the LCA arm that attaches in the middle may be off a bit but you get the idea, blue is new LCA,, red is new bar. Currently looking at the Speedway 1” sold bars, 48 spline. Based on other threads, Andy from Racecomp says the stock front rate is about 140 lbs,, and slightly stiffer would be better. Once I know the arm length I can pick a bar. Multiple holes in the arm for adjustability would be a nice thing if it’ll work without binding. An inch difference in arm length makes a pretty big difference in rate.
I suspect the shape of the arm will be a bit complex but I won’t know for sure until the LCA’s are in. The longer I can make the bar,,, the less complex the arms will be.
