3 wheelin...or dog leggin.

Ok guys, I'm not talking bout hydraulics or air ride tricks here...they used to call picking up the inside rear wheel around a corner. I'm having a small issue with "dog leggin" my BRZ and it has nothing to do with air ride/hydraulics.

I installed the Eibach sway bars front and rear. I love the performance gains felt as the car has zero body roll and stays flat as can be in corners. My issue is entering or exiting driveways with small ramps either coming or going...

The 22mm bar is so stiff that at times I get stuck with one wheel hanging, no drive capabilities due to rear diff, and a flashing traction control light. Luckily in south Florida its really flat and there's not too many of these entrances/exits of businesses with a rise that causes this. In SoCal there's tons of steep driveways as well as many other states with mountains/hills/elevation changes...

Is anyone else having these issues with either the factory sway bar or aftermarket sway bar? There's two adjustment points on the rear bar and I don't even have it set to the tightest setting. It can be amusing at times but when there's cars behind me and I can't move its not so amusing.

Apparently if you apply the handbrake a bit it will cause the other wheel to get some drive through the diff by locking up the spinning wheel.
Try that next time.

Sounds logical.. I'll give it a shot next time I'm just "hanging around"

Let us know if it works in case we get stuck too.

Cause and effect of making the rear suspension less independent. Some people will track cars without rear swaybars to prevent lifting. Wheel in the air getting all the torque is natural form from a Torsen LSD. Try the handbrake, but the true solution to getting no power with a wheel in the air is a mechanical LSD (clutch-type). A much cheaper and more proper solution is to not lift a rear wheel at all, which you accomplish by not having such a huge swaybar.

I would think that getting a rear wheel to life off the ground in a rwd car would be difficult. I'd imagine that the easiest way to do this is with a fwd car because the rear end isn't squatting during acceleration thru a turn.

If the rear is too stiff, on turn-in lifting the rear wheel isn't too hard. That being said, its usually because your braking a turning hard at the same time, which is generally a bad idea anyways. Try braking sooner and let off the brakes before your turn-in so the front tires are loaded that much. Also, a 22mm bar is enormous for this car unless you've got some impressive rear springs to resist the lift applied to the inside wheel.

All of this is a moot point on an autoX course, though I've seen people put a bigger front bar on instead of a rear bar to tame the understeer present from having to load the front tires so hard all the time.

So, cliff notes: brake sooner, don't overload the front suspension and lighten the rear end, smaller rear bar/stiffer rear springs.

No, guys...you're getting a little confused. While cornering the car is perfect with no ill handling characteristics. It's only entering/exiting steep driveways at 2-3 mph that the rear wheel will hang. If I were having this issue at the track I'd back off the size of the rear sway bar or if it was really a prob I'd just buy the mech LSD.

It's not a handling problem or issue...it's a "leaving starbucks drive thru" issue

Oh, mine does that with an 18mm bar. It's pretty annoying. There's really nothing you can do other than go faster, if you get stopped with one wheel in the air I've found it's very annoying trying to get going again.

This. Once there's load on the lifted wheel the diff will start working again.

This happens all the time to us; full droop on our car is about what stock height looks like when its sitting on the ground.

Just leave TC on and it'll automatically apply rear brake for you, or go with handbrake on a little.

Thanks Dave, I'm taking the car out for a little drive and to run some errands today...if I find myself hanging as I enter or exit a parking lot I'll try this out.

Overall I'm extremely happy with the sway bars and strut brace combination..my car is super stiff and handles amazing under all driving conditions...except leaving the drive thru lol. Someone mentioned to just go a little faster but I'd def scrape up the front end and undercarriage if I did so hopefully the handbrake is my saving grace. It would be a little embarrassing to have to open the door and give a little Fred flintstone push

The old Peeing Dog as we call it! Although we usually notice it more on track with FWD cars.

It is odd to see it happening at slow speeds in driveways though.
