Seen them before,a well known rock crawler had a buggy setup from them then it was scrapped in favor of solid axles,can you believe it was for the lack of articulation :lol:

.Would be kick stupid for high speed offroad driving and light/moderate trails where comfort is more important.Looks cool though.

Don't they make the off-road racers all IFS with all of the "getting air" they do out on a race course?

Most that I have seen(Baja and SCORE trucks) run custom long travel IFS and long travel "truck arm" style rear suspension with a solid axle,and most of them are only 2wd.There was a Dodge team a few years ago testing prototype CV front shafts that are capable of extreme angles(I believe upto 75 degrees) without loss of strength and binding,they also don't need grease or boots,made out of a titanuim alloy and about $50,000 a pop :shock:

That's just awesome. I remember once many years ago (five or more) I read about someones rig in a 4 wheeler magazine. They took a YJ wrangler and grafted on two sets of 1-ton chevy IFS, in front and back. Apparently it worked pretty well. Not as much articulation but it had no swaybars so it wasnt that crappy. I wish I could dig up that article. What you just linked to is way more custom, probably works better.

It was the famous offroad racer Ivan "Ironman" Stewart that built thye IFR/IRS Roakkrawler for competion. It was VERY EXPENSIVE and had some breakage problems.

I was thinking more like this

(for the Camaro that is)

I'm not sure I understand how an IS setup could have less articulatin than a solid axle. I thought that was the whole point to IS?

IFS is meant for a better and more stable ride,a SFA setup can always out flex a IFS unless you go to the very extreme IFS setup.Since in a IFS/IRS setup when one tire hits a bump the other side wheel does not get any of the effect from the bump,A IFS setup can also set the diff up higher for more ground clearence(think AM General H1) thus not needing alot of articulation.On the other hand a SFA/RSA setup when you hit a bump with one wheel the other wheel(on the same axle) is effected making for a harsher ride.The negitive with a properly setup SFA/RSA setup is large amounts of flex(really a good thing) to overcome the lack of ground clearence needed to get over a obstical.And generally a solid axle is stronger then the independant version.

Also - if you look at my Camaro daydream - the center is hard mounted on the frame - so articulation - is limited to the radius of the half shaft moving up and down.
while on a solid axle - the center is free to move - so your radius of motion depends on the flex of the driveshaft and the rotation of the axle - it's a much larger arc so more wheel travel.
and the IRS advantage of lower unsprung weight isn't as much of an issue if you're going slow.
