Chances are that they have the jack underneath the lower control arm. That will compress the suspension but keeps the car in the air.

Always keep jackstands on the proper body points for safety. Then you can put your jack under one of the LCAs & lift it until the car just barely rises of the nearest jackstand. This is one of the best ways to look for problems in your suspension (bad balljoints & bushings, etc...).

The stiffer your suspension (most likely also shorter), the less the wheel will drop when the car is lifted.

Droop has nothing to do with stiffness. It only has to do with shock travel.

He mentioned that the tires were "tucked". No susupension will leave your tires "tucked" in droop. How the hell would you get the damn wheels off?!?!

lookin again, they didn't have the jack under the lower control arm. matter fact on some cars, when they go up in the driveways, there on 3 wheels. i thought the tire usually drops not stay up. still tryin to find out what causes this.

if it was only jacked up on 1 side then the anti-sway bars will not let the jacked up side wheels droop very much.

good question, but i was not trying to explain why the wheels were still tucked. The sway bar may have something to do with it, but you can't say that the stiffness of the spring has nothing to do with how much the wheel will droop when the car is off the ground. The stiffer the spring the less the car will compress it, therfore the less it will droop when the car if of the ground. shorter shock travel usually comes with a stiff spring cause we dont want our cars to be monster trucks now do we???

A lot of it depends on if the setup is height adjustable at only the spring, or at the shock body as well. A setup lowered entirely at the shock body will not droop as much as an identical setup lowered at the spring. Plus you have certain setups like Ohlins PCV setups that completely seal the valves shut when set to full stiff and don't droop at all.

Why don't you just link the picture in question. This is just a difficult debate without actually looking at whats going on...

if you are referring to race cars and the like they will have considerably less suspension travel than a street car will. for example (an extreme example) when an f1 car is jacked up the wheels dont look like they are going anywhere. they only travel about 1 inch.

a lot of street car based race cars look the same as the street car equivalent but thier suspension is completley different.

you have to consider that street cars need more shock travel because of the roda irregularities that they experience but a race car wont be hitting may bumps/ comfort is not an issue, so they have very little suspension travel.

Wow, that's just..... I'm baffled.

You seem to understand that the spring will affect compression but when the weight is off the spring, what is it that you think that holds the spring in? If the spring were actually attached to the body and then the lca rather than merely sitting between them, then you'd be correct. Unfortunately, a spring does not in any way limit droop. It's purely a function of shock travel (and/or sway bar if both tires are not off the ground).

The problem we have here is that the original poster is refering to a honda who's wheels remained "tucked". We have to see a picture to know whats going on because no wheel, on any race/street car, would remain tucked in a fender at full droop (no wheelie removie)...

using extended top hats will "tuck" the tire. tuck probably isnt the right word to describe it. i think youre taking it way too literally. he just means not fully dropped like normal. im sure theres still some wheel travel, but the overall travel is significantly limited with stuff like extended top hats.

and some "racecars" do prefer to have droop limited.

Your probably right, but without this guys giving us some examples we'll never know...

yo i've heard of these super JDM UCA bushings that have so much stiffness they act like a torsional spring and suck up the suspension into the assembly, y0! combine that with my uber light LCA's and Volks and i can get my tire to tuck while doing wheelies over drawbridges, dawg!

o.g. poster: it could be a function of droop limiting, the sway bar idea sounds right too.

ive got a feeling that the original question was inspired by something like this, which you can do with omnipowers because of the short stroke of the shock.

as they say, "3 wheelin' y0!"

Lol 90% of the people in the A/C forum and take these stupid pics dont even know what a good suspension is, let alone track their cars.
