It's happened to be a couple of times so far with completely stock suspension.

I guess people figured since Florida was so flat that it would make sense to have MASSIVE drive up curbs at entrances. Don't want to flood your store? No problem, add 6' of dirt, pave it and make a 30 degree entrance.

Makes dealing with lowered cars somewhat annoying.. roads are no problem but having to pick where you can enter and exit businesses sucks.

I had to learn to do this with in an IS350 across big drainage guts. Make sure gravity can pull you back out of it, then try again. Hit it (not literally) with enough forward momentum too. It's just something you'll have to get used to.

Yeah we don't have problems like that in NJ/NY, our curbs are generally relatively low.

I three-wheel everyday into my driveway. So did my last car.

I missed the part where this is a problem? Sure the T/C goes a little goofy but it's never kept me from getting up into my driveway.

I had a FWD STX prepped MKV GTI that NEVER lifted a tire on the track or at autoX but did it everyday into my driveway. I would say steep driveways are MORE likely to do this to stiff cars than the track.

Fun Fact: When my brother has the hardtop ON his NA Miata it will 3-wheel into the driveway. With the hardtop off all 4 stay on the ground! Crazy how much stiffness the top adds.

If my car gets a rear wheel airborne, it makes strange noises and has problems with spinning either tire to get going again. I make a point not to stop with one wheel in the air anymore.

That's insane!

Again, this is how a TorSen LSD works. With a wheel in the air, you will not get power to the ground.

Yep, I just carry a little momentum up that part of my driveway that makes me 3-wheel.

Torsens are good for smooth driving rather than point and shoot. A locking differential will produce understeer.

IMHO rear sway bars should be as small as possible and only used for fine tuning on RWD cars.

BTW, even with an open rear end, applying the hand/emergency brake will move traction to the loaded tire. Pulling a boat up a slippery ramp with a non-LS diff truck is a common issue and using the emergency brake helps.

So you know exactly what I mean cause you live down here...I used to get stuck in my mini truck when I was 16 so I just threw some air ride in there and problem solved. I wouldn't ruin this car like that...

And for the comment with the miata with/without the roof..I believe it!! For many years true enthusiasts would never buy convertible versions of any car because they lost the handling characteristics. Newer technology in unibody construction as well as internal bracing has helped this but not solved it 100%. I prefer a stiff chassis for every situation..no drop tops for me.

a bit of body roll is a good thing.......sway bars are really a fine tuning tool....they shouldn't be relied upon for drastic handling changes....however it sounds like you are quite happy with its on the road performance...its only a low speed-driveway scenario that messes it up.....I would just pull the e brake a bit to put tension on that wheel

On track I see LOTS of race-track cars that have way to much sway bar....BMW M3's are quite bad at this....then tend to lift the inside front tire on almost every corner....while the inside tire is dragging and not contributing much to your overall cornering force...it DOES add some..... On my last racer I was chasing a Z06 in around a 60mph off camber irght hand corner....a prelude blew its engine on the race line just before apex.....I hit the oil with both of my inside tires.....car instantly started understeering towards the edge or track.....traction came back just before I went off and drove off under control..... three cars right behind me got sideways and nearly hit me in the dirt.... Moral of the story....car was on the limit DRAGGING the inside tires...once those lost traction...the outsides were over loaded and a skid resulted...

My current race car only runs a front bar....the rear is disconnected....since I want the maximum traction I can to accelerate OUT of a corner....you win the race getting off the corners the fastest!!!!

Funny thing, I removed the front sway bar on my last car to reduce understeer. The stiff suspension kept the body roll in check anyway, but I felt like the outside front tire (FWD) was getting over-loaded at the limit. I removed the bar, and the car became amazingly neutral. A neutral FWD can be a blast.

I do agree that the sway bar should be used for minor adjustments. A stiffer suspension has less need of a stiff sway bar. Just my opinion.
