Thought I would add my thoughts to the IFS debate you folks seem to be having. First the pic above of the desert racer is application specific and works well in that enviroment, but not as well in rockcrawling.

IFS in stock form (or even in that desert racing form) doesn't lend itself well in highly articluated situations. Its because of the design the traction is less in high articluation as the arms try to keep the tire in its camber. IFS would do well in straight or v climbs tho, but not substantially better than solid axle.

Do I think that IFS could do well in rockcrawling...Maybe in some situations, but not in others as noted in my comments. I have had thoughts of trying to address the concern with being able to change camber live and may someday play with that.

You may see more IFS in the future as rockcawlers try to lower CG and the axles start preventing that, but it will take a highly modifies arm system to be effective.

Good points on the IFS, and though i agree the relevance of the type of use, I havent seen anywhere where the "specific" use has been stated here

Simply something was wanted 'outside the square" so to speak, hence I attached a pic of Walker Evans vehicle, which was a little outside the square, and lacked development time [Walkers own words] and he was keen to go IFS on the next truck as well, and develop it over a longer period.

Anyone can copy a design that works, not many can create something that does.

One note, Walkers new rig is a moon buggy (rear engine) with solid axles front and rear. So did not pursue IFS/IRS any further.

And I guess, in what he designed, its a little difficult to measure how worse, if any the IFS was, and how that translates to what the average person uses, whilst developing on the fly.

But just the fact they were looking at it, says it cant be all bad, just not developed enough to be in the top 10 in one small part of a motor sport catagory.

Wow, I was only looking for a shortcut!

Sorry, didn't mean to stir the fire up that much.

Relax Steve, some go looking for a topic that will do that, some go looking for a topic that has that, and some just post what they think
