What does too much rear swaybar look like...

Too much rear bar, combined with sticky tires. It was pulling the inside rear off the ground than transitioning to the outside front trying to life on corner exit

Looks fine to me. I get that kind of lift without that kind of weight transfer. Your front end is dipped pretty good there, so you were on the brakes just before.

This on heavy deceleration, I think I was braking:



This is just a lift through a box, IIRC, at 45mph on a gravely/old asphalt lot:



This is just a lift for a 45ish degree turn:



Not sure if braking was involved here for Adrian:



Here I am slaloming with a lift (and I think smacking this cone, can't tell):



By bar is set to it's 450ft lb/in setting. It can go 350-550ft lb/in, in 50ft lb/in increments.

A 22 or 24mm Cusco RSB is about 95ftlb/in, for reference.

I thought it was when you ripped the mounts off. Did that a couple times on my old Maxima. BANG and suddenly the rear suspension is different.

What Gagan said, it looks fine to me. Jourdan' car does that all the time, too.

That's what I was thinking. As long as the rear isn't washing out, it's just more happily planting the front...a la old school GTi!!!

Indeed! Less traction in the rear makes rotation easier which is always fun.

I actually used to run an '83 GTI in FSP... probably the most fun car I've ever owned

I'm running the RCE bars front and rear (25.4mm solid I think). Front was on full stiffness, rear was on the middle. The car was controllable before, but since I tossed in stiffer springs last week, it's just made it too non compliant in the back. The pic is actually from before I put the springs in.

I think the problem is that the AWD is freaking out when the car transitions from lifting the rear wheel to the front wheel. It barked the outside front tire HARD a few times on Sunday

I used to think that, then I realized that the mounts are just weak.

The RCE bars are hollow not solid. They are roughly equivalent to 22mm solid bars (like the Whiteline bars).

How's about we take an actual look (attached image w correction) at the vehicle without the camera all tilted for the "added-effect"?

Looks about fine to me, yes slightly too much lift, but that may not be all swaybar, someone was carrying too much speed and didn't scrub off enough into the apex. Look at the front tire sidewall getting rolled.

That just means that the tire pressure is too low. Or not enough camber. But Tire pressure is easier to adjust.

But even with proper pressure, there can still be a lot of sidewall deflection.

I do enjoy some good tripod action.

The only real negative effect is if your rear diff is open (like mine) you can't put down any power if there's a wheel in the air. The free wheel will just spin until it gets back on to the ground.

I am afraid however, that if I spin that wheel too much and it hits the ground, it could do some damage to the axle and probably the diff.

I don't know, on top of not scrubbing off enough speed, I suspect you don't have ENOUGH roll bar on the front. It looks mighty squishy up there, not at all flat.

I am still doing tweaks to the FXT but with 25mm bars, and 350 springs, I should be able to hold it damn near flat in the turns.

350 is probably too soft. I would go 400/450. Based off that I'm running 350/400 on my impreza and the forester is a bit heavier.

It would probably be an issue if you had a lot of power

Are you getting enough rotation with the setup? Are you pushing anywhere along a turn?
