I solved that by tossing my front lip... looks good but what a hassle! Function over looks here, but for others that's not the case. lowered 5/8th of an inch and I have no problems even with the steeper driveways.

the wheel up in the air spinning is the torsen LSD at work. not sure if you're putting more wear and tear on it by spinning the wheel like that.

carry a 2x4 with you and stick it under the wheel... haha

i know exactly what he's talking about. because you're going over the driveway sideways, the suspension travel is not enough to lower the wheel down to the bottom of the dip, so that wheel is up in the air. due to the way the torsen lsd works, you lose power to the ground as that wheel spins in midair.

The only way to remedy this is to get a non-torsen lsd, suspension with longer stroke, or just do what i do and try to rock it back and forth till it makes it up lol.
yeah the car is not bottoming out ..sounds like you get what im trying to explain..

I wasnt sure what forum section to post this in ..but i was wondering how many of you this happens to, I have tein flex suspension lowered around two inches, so gotta get on those driveways at an angle but sometimes i guess depending on the driveway, if i go up the driveway with the pasenger wheel first it seems to lift the rear passenger side enough to where the rear wheel doesnt have anough grip and skids, so i sometimes gotta come back down and catch a little more speed or give it gas meanwhile skiding untill it gets grip and makes it up the driveway.. this doesnt happen to often but when it does its kinda a hastle and sometimes a little embarrasing so was wondering how you guys deal with this isue or do you just live with it and avoid those driveways like i been doing..?
since i got my spoon diffuser, i have to attack steep inclines the same way... what I find best is to take the steep part on more of an angle, then once your back wheel (one that is spinning) is on the incline, turn the steering wheel straight up the slope.
havn't had wheel spin since.
Another tactic is to carry a little more speed until you can feel that back wheel on the ground, then give er

well, with a torsen, both wheels need friction in order to work. When one wheel gets lifted up, it basically becomes an open differential where the wheel with the least amnt of friction gets all the power.

What you CAN do is create friction on the wheel that is up in the air. How?

Easy. Pull the ebrake up a little bit. That creates friction and will allow the other wheel to start spinning allowing you to get over steep driveways.

Most aftermarket coilovers especially the JDM ones all have this "characteristic", some of you guys have already summed it up, it's pretty much in reflect of the suspension shock having not enough stroke/travel, the monotube design for our cars are relatively short, hence this one wheel lifting occurs.

I'm so used to it now, I don't even think about it. Apart from getting the angle right (this is mostly to ensure nothing scrapes and your fenders don't get murdered), the only other thing you can do is what s2kobsession said, carry a bit of speed before taking the car up, that is the only smooth workaround.

Or you can get a buddy to push down the car on the rear, while you accelerate, (where the wheel is lifting/off the ground). I wouldn't be doing this, unless your buddy has experience on how much weigh to add. Too much and he could end up denting something.

why not just remove/unbolt your rear sway bar? with a car THAT low, you prob don't care about the handling effects anyway

Err no, you don't need to have an extremely lowered car to have this problem. It has nothing to do with the stabilizer bars.

It's merely a design characteristic of aftermarket shocks.

unless the complete free travel of the shocks is a 2 inches, then yes it does have a lot to do with getting high centered.
