hey guys,
I was wondering if you could clarify a couple things about beams. With all the allowance of FV disc brakes, it kind of put me down a rabbit hole of thinking & digging... what exactly is needed to convert a link-pin car to a BJ beam?
I did find a bit of info on the FST page that says "When you first get your new beam you will notice that the four mounting holes are not spaced the same vertically. You can use three methods, the first is to weld a plate over the beam holes then drill the 1200 pattern into the beam. The second thing is to use the bottom holes to mount to your frame and then re-drill the upper holes in the beam. You can go one step further and modify the beam mounting holes on the chassis and change the hole location to match the ball joint mounting pattern."

So if I understand correctly, this means the lower tube & mounting hole stays in the exact same spot, and just the upper tube & mounting hole moves upwards?
If so, how much does it move?
Are the tubes the same diameter?
Does this change the ride height of the car?
Is there a change to track width, measured at the wheel mounting face?
Like I said, it was one of those rabbit holes that makes me wonder why we can't allow BJ beams & avoid the offset bushings, etc. Might be an opportunity to make another small step forward in time.
