I know full well what the std beam does, just saying for prices it may be possible to isntead get struts which are a millions miles better in every way than a beam will ever be.
The beam with the modded mount points imo is expensive for what it is, but is about as much as you can do if keeping the beam arrangement.
Undersquat there is even more force pushing the WHOLE width of the tyre into the road.
Read some good chassus books such as chassis & suspension engineering, by Geoffrey Howard, even has piccies of the twin tyre wheels, now they would seriously brought the modern car forward in grip terms!!

Side wall flex dose not take up the negative camber problem the standard rear beam has under acceleration lol thats the big problem with the sierra rear beam hence the modded rear beam! and as for twin rear tyres lol are u realy being serious. But ill agree with u it is a lot of cash but people who do have it done say it give u so much more grip!
