The way i see it theres 2 categories
Theres stanced then theres "Hellaflush", to try and put it in perspective i'll use some z pics i collected over the years haha
Stance is not all about big wheels and deep dish and crazy offset. its about getting the car to look like its tough and means business.
i do believe most people think its the former but would be more focused on getting a "flush" (a less aggressive version of hellaflush) look rather than good stance.
Alot of the cars here and many many zed's have perfect stance. the way i see its a combo of the right wheel width, offset and tyre combo and height that achieves good stance.
you dont need to the drop the car to the floor, you just need to get your offset right so that the wheel rim is almost if not in line with your wheel arch... wide rims always help as dish or concave can really enhance the look more than a flat face rim. From there its all about tyre combos, too stretched and you'll get too much of a wheel gap and need to lower the car alot, too fat and sometimes you can look like you're running on ballooned wheels you need just the right combo where you can fill up most of the gap without it looking too thin/small or too ballooned. Finally, you adjust the height to achieve that tough look. get it right and you wont sacrifice handling etc. (alot of the time attack and d1gp cars have great stance)
stance, you can see its not slammed and theres still wheel gaps but the car just oozes toughness and means business.
stance but geared more towards "flush" ie. no wheel gaps
Hellaflush is the next step up from just a stanced car where you have the insanely dropped cars with big poked out rims, super stretched tyres, almost "Demon" camber and lowwww offset. The look they want to achieve is that the lines of the car flow straight to the wheels ie. no wheel gaps and not much tyre to be seen. its a very photogenic look, but that the same time you are sacrificing so much in terms of ride quality (scrapes and bottoms out on everything) the amount of guard work u need to do is crazy and you basically wreck the handling of the car with the height/camber you need to run.
for australian roads you'd be silly to follow the hellaflush culture cause our roads are shiet, we've got speed humps and potholes everywhere.
you'd be denting fenders and destroying the underbody of your car to achieve the look.
heres an example of "hellaflush" in a zed. thats not that crazy unlike some other cars.
personally, i'm all for stance. but its a fine art and you need to think about how to achieve it without sacrificing too much.
most people have geared themselves more towards the hellaflush movement so you'll always get internet warriors saying that your car isnt low enough etc.
build a car with the right stance they wont say a peep cause it just looks so tough.
my 2 cents
