Handling- roll overs.

So I have been trying to figure out how to avoid flipping my Yeti all the time. Obviously on blacktop if you make a hard turn its going to flip. The foams were to soft so the tire would fold over and send the truck in to a cartwheel.

I stiffened the suspension and added CI closed cell foams and it helped a lot.

On loose dirt like a baseball diamond or a gravel parking lot where you can make it break loose and slide it does fine but it still hooks and flips on high traction surfaces like concrete which I expect.

My question is in grass or loose deep sand the front tire still digs in and sends it in to a cartwheel. Is there anything I can change in the suspension or alignment to help with this or do I just need to change my driving style?

I thought about that but it doesnt seem to have that much body roll on things like sand, it just seems like it is planting the outside front tire to hard in a turn and it digs in and flips it.

Are there any other suspension adjustments I can make from the stock settings that would increase the effect of the swaybar other than buying the stiffer swaybar rod?

I wondered if changing the camber and tipping the top of the tire in (negative camber?) would help it not dig so hard in turns and if it would have any negative effects by doing that.

The reason its planting the front tire is because body roll, whether you can visually detect the roll or not. Your only option outside of getting a stiffer sway bar will be to stiffen up the entire suspension all the way around. This however would have negative effects on its ability to cope with bumps. Suspension tuning is all about a game of give and take.

front sway bar might help.

That's a good idea as well.
 
Grass and loose sand I don't think you're going to be able to change enough to achieve anything and if you do it'll then be bad to drive on other surfaces. If you really want to change the set up then you need to reduce traction of the front wheels. Stiffen the suspension with springs and sway bar, set up as much positive camber as possible, change tyres to the hardest compound you can get etc. It'll still roll in sand and grass if you try tight turns at high speed IMO.

A better solution is to change your driving style. Set it up for the surface you run on the most then for other surfaces drive differently. That's what I do.
 
You can also try running on open rear diff. You will be to stay on the power in the turns a little more
 
Try moving the shock down the trailing arm to the point closest to the rear axle. This helped mine stay flatter in corners. I'm running 20wt with white springs in the rear with good results.

Sounds like the issue I had with my RTR Yeti.

The front diff was too loose so power would transfer to the wheel that was in the air, causing the wheel that was still in contact with the ground to stop, flipping the car.

I stuffed the front diff with chunks of Mack's pillow soft earplug and it stiffened it up enough to eliminate that behavior.
