It helps make it easier to design a well balanced car who's dynamic capability scores well under all conditions. Maybe not the best at everything, but good in all areas so it's a good all rounder.

More weight to the back gives better traction but trickier oversteer, more weight to the front gives, I guess, more predictable handling. More weight near the middle gives more agility and more weight near the ends gives more stability.

More weight higher up and it falls over To that, add how much it weighs, how high the weight is, what suspension it has, how well it is set up, and a hundred other things that can ruin a car with perfect distribution, and make a legend out of a car with a sub optimal weight distribution.

I've driven cars with weight distribution and loved their handling and enjoyed driving them, and I've driven others also with weight distribution and been completely underwhelmed by them.

It's a flexible arrangement. If the rest of the car lets you take advantage, then you have a car with decent traction, flexible handling traits - i. if you want a bit of safety valve understeer or some more indulgent oversteer, the choice is up to the driver and is dictated by how you present the car to the corner or even how you set the car up in the middle of the cornering.

It's a balanced car, and that allows the driver to adjust the balance all the way around a bend to their preference at that moment. If the rest of the car allows it. Cars with distribution can have great character but not guaranteed by the weight distrbution Cars with unusual weight distribution can also have great character because of it.

Some might offer the driver less flexibility and need to be driven in a particular way to get the best out of them, but they can be just as rewarding because of that thinking of the here. I can't say I care too much what the car's distribution is, nor its engine, ride height, gearbox type and so on.

It's the sum of its parts that matters because the cars with character can overcome a flaw in any of those areas. It's how it feels to drive that matters in the end, and distribution is just one of many tools that help define that driving character.

Intuitively, it seems like a perfectly-stiff car with weight distribution is going to be able to change direction more predictably than a car of the same mass, tyres etc but with the centre of mass moved fore or aft, as it will have similar lateral grip on both axles.

Not being a proper engineer I could be wrong, but wouldn't there be a torsional moment along the axis of the car if the mass is concentrated to one end, with a resultant deflection between the axles that would then move the suspension geometry further from the ideal? anonymous-user 52 months.

: Optimal weight distribution

Marketing, physics and busting the 50:50 weight balance myth	Be forewarned, there is no scientific data ahead. Access SAE MOBILUS ». Krikkit 26, posts months. There's a bit of physics going on that many over look. A rear engined car will not have better braking because of the positioning of said engine. This is the case with pretty much all muscle cars.
Why is 50:50 "perfect" weight distribution?	Handles surprisingly well with no sway bar up front, TruTrac, torque arm, and Crown Vic bar out back :. telling us that and not telling how the next one will be built for Challenge money and NOT showing Pics is just WRONG. Stampie may have something new coming along those lines, OR Why the trip to Huntsville? Don't they build rockets in Huntsville? Maybe I grabbed one cheap from a rocket scientist. In every other situation, rear weight bias is beneficial. As others have said, when the brakes are applied, load transfers to the front regardless of car design. Therefore, braking effectivity is greater for the rear-biased car. The exception is high-powered drag cars where the front tires lift off the ground; in that case, it doesn't matter what the static weight distribution is. This example above shows the problem a rear-biased car can have where under acceleration, there may be so little weight on the front tires that understeer becomes a problem at corner exit. Also, and as has been pointed out. In a turn, lifting off the gas transfers weight forward in all cars. At the same time, engine braking is trying to slow the assumed rear driven tires. The combination can be a bit like pulling the emergency brake and in an already rear-biased car, makes the rear tires more prone to stepping. As was said, using tires width proportional to weight distribution can do a lot to retain the benefits of rear bias, and also undo some of the tendance to spin. In short, a rear-biased car is more capable of better track performance, but it also puts the driver closer to the edge of controllability. It comes down to driver skill whether the car is faster in reality or just on paper. I have owned a couple of cars like that. My 72 vintage was so bad that even thinking about lifting the throttle was enough for it to try to bite. I never owned a car that so actively tried to kill it's driver. You'll need to log in to post.

We found that corner weighting is much more important than front to rear bias. only In every other situation, rear weight bias is beneficial. Stampie said: In reply to GTXVette : Don't they build rockets in Huntsville? If he's Just A Rocket Scientist, Well It can't be much then. May as Well be A Toll Taker on the Turnpike. the answer, of course, is "it depends. in general, it is the non-linear nature of the friction-versus-weight behavior of automotive tires which allows us to change the handling of a vehicle with things like fore-aft weight placement and side-side anti-roll bars. for any total vehicle weight, maximum cornering force can be generated by four equally-loaded tires -- if the tires are all the same size. uneven weight distribution can be balanced with different tire sizes, different inflation pressures, alignment specifications, etc. as far as being able to brake later, that's purely a function of how sticky your tires are and the balance of your brake system at the max decel that your tires will support. are you in a professional field where your employer might pay for you to take a course from the Society of Automotive Engineers? i'm an assistant instructor for the SAE's "Applied Vehicle Dynamics" course, and in this class we spend three days alternating between classroom lectures and on-track exercises, to bridge the gap between textbook and track. It is an experimental thing. There are so many factors that weight distribution is low on the list. It depends on how the car handles. One thing, less weight on the drive wheels reduces traction. From experience with my ZX2-SR which is also a DD, a much stiffer rear sway bar and extra camber and caster on the front along with wider wheels and sticky tires makes a very good handling car. Ok, thanks, Ice and Angry. I just wanted to take it a bit further to see if I was missing something. Side note. Nothing to do with the topic but while I'm on here- The EP3 Civic Si 4. I used to get around but with some hypermiling techniques the last tank average was It makes driving on the street a lot more interesting. The ideal weight distribution depends on a lot of factors. A lot of the decision depends on how much tire you have to work with. If you are using very limited grip tires, you may want to have more rear bias to get higher cornering speeds. The downside is it reduces acceleration capability, which IMHO is more important. If you can get enough tire, I think that the ideal bias is as much as possible on the front of the car. When I say enough tire, I mean a tire with enough grip to lift the inside front wheel. If you have enough grip to reach the physical limitations of the mass and width of the car, then you are just giving up acceleration by having more rear bias. As an example, my 86 Civic EP racecar can corner at around 1. This is the point where the whole inside lifts off the ground. That is the physical limit of the car's CG and width, but I have enough tire to genrate that much force on a good surface. I have intentionally moved as much weight as practical to the front of the car to reduce the polar moment and increase the acceleration traction. In my case, the limiting factor is not the tire's ability to generate cornering force, it is the roll stability of the physics of the chassis. Even if the tires do saturate before the physical limit, they may still pick up more acceleration ability than they lose cornering ability as you add weight to the front. If you can move weight around easily, I'd recommmend trying a few setups and see which is faster. the weight balance itself will only become an issue if the handling balance is already near perfectly neutral will cause the car to lose traction in a sudden and unpredictable manner. The closer the car is to perfect the more unpredictable it will be. As a for instance, NASCAR racers shift their weight distribution depending on the race track and not just side to side. And interestingly, a few engineers I've talked to say that it's more important to get the weight on the front tires equal rather than the cross weights. From there, you also don't have to worry about moving a bunch of weight from the front to the rear moving the weight further towards the rear than the car's CG will actually increase the car's polar moment making it turn slower. Thing is, drive train layout only comes in to the equation on corner exits. and no matter what you do with weight distribution a FWD car is still going to tend to understeer once you get back on the throttle coming out of a turn. BTW, re read the section on tires and how they make traction. As in when weight is applied to a tire that tires traction output increases, but at a decreasing rate. Problem is, there's no way your going to get that with a FWD car with out adding weight, which is counter productive. And in the end on a FWD car, your best bet is to simply reduce weight overall as much as possible and then tune the suspension to work with what ever weight distribution it ends up with. which as my friend puts it means that your civic will have all the weight distribution of a lawn dart. I dunno about all the mathematical stuff, but a guy here in SC runs a VERY fast FSP Rabbit. The only downside: he had to add power steering to combat the torque steer. He agrees that you want the weight up front on a FWD car. I don't think he acknowledges the value of reducing the polar moment as much as I do. This is really the key to understanding why there are some cases where a FWD will be faster than a RWD.

Optimal weight distribution -

A quality set of scales set up properly will reliably deliver more accurate readings, enabling you to dial in the best setup possible. Raise the tire pressures to their anticipated on-track pressures, and position any ballast in the car where you want it before proceeding to suspension changes.

Every time you lift and lower the car to make changes, the suspension loads and unloads, and wheel positions sit different from how they would on track. Be sure to roll the car back and forth onto the scales and bounce on the corners to reset these items to replicate their normal state on track.

Vehicle weight distribution changes drastically through a corner. Finding the ideal crossweight enables the driver to get the best handling and drivability out of their car.

A Weight distribution is static as the car drives a straight line. B Braking in a straight line shifts the weight forward, planting the front tires against the road to aid in deceleration. This improves car rotation, slightly drifting the rear end to set up for a better launch out of the corner.

E When transitioning from braking to accelerating, the outside tires handle most of the weight and needed grip.

F Similar to trail-braking, accelerating out of the corner blends a small amount of turning, as weight transfers from the outside tires to the rear. The straighter the car is, the more traction is available for acceleration.

Before starting, adjust the scale pad heights properly so that they provide a perfectly flat platform. You will also need shocks with adjustable spring perches in order to make changes to weight distribution. Adjustments to corner weights is done backwards from what many people might expect.

If you lower a corner of the car, you might expect that corner to get heavier because of the car body leaning more on that wheel, but this is not the case.

If you lower the right front corner of the car, you are raising the right front wheel on the suspension like shortening the leg of a chair , reducing the weight it exerts onto the ground.

Reducing the weight on the front right corner will also reduce the weight on the left rear, and adds more weight to the two remaining corners. Raising the corner will accomplish the inverse. The purpose of corner balancing a vehicle is to get the crossweights equal center diagram for equal handling in both left and right turns.

The same is true for the total weight on the front or rear of a car. Only by moving weight can those balances change. Keep in mind that making a change to just one corner will affect the other three, so make small, incremental changes.

The first time going through this process will prove a time- consuming process, so take notes on how much each adjustment in the corners modify the weight distribution of this specific car. Having this for reference can save a lot of time for future setup or when making changes on the fly at the track.

The inconsistent handling and unpredictability between left and right turns makes for a headache of a driving experience and a dangerous environment for yourself and others. Skip to content Thursday 15th February Search for:. March 21, Education The Tech.

When The IROC Series was started they used 's ,and even with Jay Signor's mispell top notch prep he couldn't get around a corner any where. Mark Martin had it down. Lots of Sevens have a slight rear bias.

Only thing is you gotta put your foot in it when you get in trouble. You will have to adjust tire width, spring rates, sway bars to match the rear bias but once you do that, the car should be amazing. I find a rear weight bias preferable. Braking is greatly improved with a rear bias, as is acceleration.

If polar moment is kept low, handling will be great. Depending on how much you have the throttle becomes your rear traction control device. Rearward bias uses all wheels for braking more evenly and puts more weight over the drive wheels assuming RWD.

Yeah a little rearward bias isn't bad at all. The nasty handling trait to watch out for as weight distribution moves rearward is when the car swings toward the outside of a corner if you lift off the throttle mid-corner. The AW11 MR2 and the Lancia Stratos have this, and some rear-engined Porsches, especially older ones, have it so bad that the car initiates a violent spin toward the outside of the corner.
