YOUR SEARCH:

me seem, not all are understood as and why different nuances are reflected in the behavior of automobile. In particular, the modification of suspension is such "shamanstvom", which I learned many years (I learn, until now). I thought that the survey of an improvement in the high-speed qualities can be useful for the number of the readers, in particular the rarely discussed problem of an improvement IN THE DRIVER.
Further I understood, that there are many things, about which I could write; therefore I decided to break this survey into the articles. In this article 4 of sosredotachivayus' on making of a driver more rapidly. In the following part I will discuss, as changes in the suspension they influence controllability, and why a change in your suspension can make an automobile more rapidly. In the third article... it is good, 4 I do not know, there will be the third article. Profit- Will see...

OBSERVATION: This entire material - my personal opinion. Possibly 4 V by something I make mistakes. If you take some pains yourselves to read this, try to act as in the product store: take that which pleases itself you and never mind to the fact that to you it is not necessary.

However first, I wanted to stop at the philosophy of rapid ride. There are three types of "rapid automobile":

1) appearing rapid (the "showcar").
2) Yedushchiy it is rapid along the street.
3) Yedushchiy it is rapid along the racing route.

I will leave the considerations of point [ 1 ] for the European automobile periodical, since precisely to this they devote the large part of their editorial budget (retarding discs with the grooves "for the cooling" (sic!) and the "sport" shift knobs of transfers).

Number [ 2 ] can be divided into two camps: amateurs to start from the cross-roads and street slalom skiers. To the amateurs of rapid start is necessary the maximum acceleration: they want so that them BMW would work similarly to American powerful automobile. In my sincere opinion, if to you is necessary rapid acceleration, iditol you will purchase to itself American automobile with the V- descriptive 8- drum cursor. Slalom skiers - home-grown racers, who fly in the turnings of usual general roads. One misfortune: the driving Of ee' Me on the limitation is excessively dangerous for the road, along which will go the rest. I live at the foot of cascade mountains in the solar Pacific Ocean state of New York. Here everywhere - road with many turnings. I can conduct machine at the reckless speed, never approaching a limitation strictly of machine. This is simply unsafe... Thus, an improvement in the controllability of the automobile (see [ 3 ]) will make high-speed driving along the usual road more captivating.

Give let us have a talk relative to number [ 3 ]. First of all, is a space from the completely standard automobile, which they govern sometimes on the training route (in the driver schools) to the especially racing machines. In the first you have simply good automobile, such as developed "gnomes from Munich": convenient, safe, predicted. The secondly (for example, IMSA M3) you have an automobile, completely optimized for the speed: inconvenient, dangerous in the less than professional hands, much that less predicted. The automobile, ideally disposed under the racer- pro, would be killing in the hands of simply competent driver. Your automobile somewhere in the center between these extremes is located. Each serious modification, which you produce (i.e., the hand-lever shifter of transfers it is not considered) it moves your automobile to that or other side of this space.

That, you strive for what, is determined on the basis of your requirements (daily ride, radio, the rear seats) and desires (rapid time on the circle, the gain of race BMW of club so forth.) Thus, we come to three possibilities to make your machine of the of more rapid:

1. To improve driver. This is - the cheapest and most rapid way to the larger speed. Michael Schumacher could sit down into your standard 32п and pass any of you on track Laguna Seca, even you will go into modified M3. to this many reasons: strategy of the attack of the route (knowledge, where to go rapidly and where to go slowly), the presence of the ability to find the limits of automobile and to conduct it on these limits, smooth control for averting the speed loss with slippage and loss of balance and so forth

as you can improve driver? Knowledge and practice. Knowledge can be acquired in BMW CCA/ACA schools, professional schools (Russell, Barber), the books and video. Two books, which I extremely recommend - Poul Frere "Sports Car and Competition Driving" and Alan Johnson "Driving in competition": both are classics. I read Frere (known with many from its work for Road&.Track) into 1970 and this forever changed my style of driving. Alan Johnson (repeated champion SCCA) described how to divide the turnings of racing route into three categories, and as to distribute them on the importance. Another key field of knowledge can be obtained from "The Physics of Racing" one of my colleagues, Brian Beckman. Although physics can seem by complex for not -texnar4, this is - the important part of understanding the dynamics of transportation means, which is necessary for the driving of automobile on the limit.

The practice - this in all time, carry ouied after the control. Insufficiently simple to leave and to cut circles, if you do EVERYTHING incorrectly. A large quantity of novices tries to immediately move too rapidly, and in this case they acquire some terrible habits, from which it is very difficult to break. The best method to learn lies in the fact that to have competent instructor, who ensures a constant control and management. However, this is rarely possible, and many of us very often occur on the route singly. Here are some things, which I sharpen in practice on the route:

- conduct machine smoothly. If you can learn to be smooth, speed will arrive more lately by itself. You remember that the rapid circles rarely appear most gripping. The motion of automobile by side in the turnings eats a huge quantity of speed. Blocking brakes worsens the balance of automobile. Any book or school of driving emphasizes this point: You must be smooth.
What is to be done smooth? Try softly to enter into turning, instead of the attempt to cut off by its angle. Attempt to pass turning so as not to correct the trajectory of motion. Your purpose must be this motion in the turning, with which you smoothly turn control in the side of turning before reaching of apex, and then you smoothly equalize it conversely.
Each time, when you sharply turn control, you substantially lose the real speed of automobile, and you also strongly disrupt the balance of automobile. Do not torture in vain the brake pedal and accelerator. Use your tips it is finger be switched slowly and softly with the gearshift. Superfluous excitation and pulling of lever will improve neither your time on the circle nor your transmission.

- practice in the ride along the optimum trajectory. On the racing route there is a set of trajectories, and that which is suitable for the races of the club of Ford, can not be best for your M3. for the beginning consider that there is two trajectories: for the dry and rain route. You will ask someone to show you them, after which them constantly sharpen, until they are put off in your memory. In the ideal you must have control points for the braking, entries, apex and output for each turning. Sometimes in the schools at these places chips are placed; search for anything constant (mark on the asphalt, the beginning of fence, anything) that you can memorize after someone catches chip (I I personally set as its goal to try to touch each chip of apex in the driver school: I make this not of the hooligan motives. Simply I am trained, using EACH IN of route. You you will be astonished after learning, as many people disregard this).

- support automobile in the balance. I constantly heard this expression, and it were assigned by a question, however, that this in reality indicates. This indicates exactly the same as tells: in the ideal you want to have the identical load (weight) for each of four wheels always.
Since in reality you cannot ensure ideal balance, except as in the machine confronting, you must constantly attempt to remain so closely to this, as soon as it is possible. In my following article I will discuss, as the adjustments of suspension they influence the transfer of weight, but I will thus far assume that your automobile - completely series. Let us attempt to present load on each wheel during the motion of automobile.
Torr causes the transfer of weight from the rear wheels to the front of wheels; acceleration - vice versa. Braking with the left turning loads most of all right front wheel and unloads left rear. If you from all forces press to the brake at the end of the straight line, the front of machine will become extremely heavy with respect to the back: automobile more not will be balanced. Intermittent braking will cause the smaller transfer of weight, respectively automobile will remain more balanced. They did see how this does work? One of the main reasons for the smoothness of ride - this is the retention of balance.

- use your sight. Generally speaking, when we learn anything new, our view is narrow and concentrated. With the experience we begin to look wider and more obshcho. When you for the first time go along the route, you look directly before yourselves. Experienced drivers know how to look far forward, also, to the sides. They think about that, where they want to go, but not about that, where they will go at the given moment. You no longer can make anything with your current position on the road after you in it burn, you already this passed. You look there, where you want to go further, and automobile will follow your eyes. Here is the exercise: when you pass entrance point into the turning, you look at the apex. When you reach the apex, you must look at the output from the turning. During the motion try to focus attention on the fact that you see by outlying sight,; you must be capable of looking along the sides without moving the pupils of eyes.

- concentration of attention. You will recall, how you were sosredotochenny, when very first time settle for the control? You are later, probably, they ceased to think anything about control of machine during the motion according to superhighway, tuning radio, stirring on the telephone, or popivaya of coffee. The more to us anything is familiar, the more difficult it is to remain on this concentrated. On the races this occurs in exactly the same manner. Here one of the reasons, on which the average and moved drivers more frequently fall in the alterations than novices. On the route the difference between the srednen'kim and great racer - concentration. Fortunately, it is possible to learn to this. With the braking try TO FEEL brakes, as they approach blocking of wheels. Think: can you impede somewhat stronger, or this is limit? When you press accelerator at the output from the turning think: automobile has a tendency toward the drift. You are ready to resist this? Feel the behavior of the automobile: you can perceive the small slippage of rear axle, before this process it will become uncontrollable? Who behind me? Who is in front? Dvizhutsya they more rapid? Or it is slower? If the automobile before you in following second does carry, where you will go?

At all this I work, when I am located on the route, but all this it is possible to learn, also, with the simple motion around the city. To you not compulsory to go rapidly, simply be trained for this. For example, try to pass by wheels exactly, where you want. Can you say, where they? Can you only only kosnu'sya of the edge of border by external wheel on leaving from the curve? Can you zatormozit' to the total stoppage, so that the automobile would not rock back? Can you change gears so smoothly that this is similar to the automatic gearbox? It is difficult to develop all these habits, but, fortunately they can be acquired in the daily trips around the city or into the store after the milk.
I was trained to this in all my automobiles, including my 6.5- liter Suburban (yes, not too soft a machine: -).

Be trained in everything this until this ride becomes for you natural - you will become more rapid, having spent not penny on tyuning.
