A major part is the fun of dri ing a good-handling car. The phrase ma 1 a11d machine have becume one best descr bes good handling. For the various types of racing, go d handling is essential-even on the drag s rip. Handlipg involves all conditions found in drivingLacceleration, straight- jne driv ing, bra g and cornering on good sur faces and ad. The good- handling car wUl be contro able and predictable in all these con ilions. Naturally there are comp omises, and the use of the car will deter 1ine how to make them.
A good street car may have a gre t combination of ride and cor nering on street tires, but will not corner as fast as n all-oul racing car racing rubber. A racing machine may wear you out on. A car set up for oval-t ack racing will corner poorly on right-han corners, but a racing sporls car will not I p a hjgh-bankcd track as fast as the car se up for left turns only. Good I andling means superior trac tion. This is lack of wheelspin or axle hop in acceler tion, maximum braking power on all sur aces, and outstanding cornering speed.
He e again we are faced with com promises. No matter what type of car you drive, from family sedan to grand prix racer, it can be made to handle by s in this book.
Heres what can be done in an all-out effort to get better handling on the street. Besides the obvious lower ing of ride height, the car has many hidden improvements lnterpart Mulholland springs on Koni shocks, 23mm anti-roll bar front and rear, Goodrich SO- series radial TA tires on 13 x 7 mag wheels.
Solid bushings are used in the suspension pivots. Mitchell steer ing rack in stiffer rack-mounting bushings gives quicker steering response. Stopping is improved with Velvetouch brake linings, steel braided brake hoses. Brake cooling ducts are in the front spoiler. This car is an ultimate street machine, and is only slightly illegal in California.

This book deals with all the Chapter 2 deals with the reasons for intricbte problems that are common to good and poor handling. Understanding racink machines. Here are s for sus-the reasons is vital when working on your pensi6n tuning and modification tech-car.
A great deal of time and money is niqu i s. You will find that it is possible wasted each year by unined people to co wert an everyday sports car into a trying to fix handling problems. For adjustment. Many professionals can do a fine job of making the factory settings, but are not trained lo alter ltandling with suspension adjustments. You can be your own expert after understanding Chapter 3 and doing some experimenting. Chapter 4 explains how to get the right parts the first time.
Too many car owners go to the store and come back with wide tires, mag wheels, and heavy-duty shocks-and then are disappointed with the results. The tires may hit the body because the wheels are wrong. The shocks may hurt the ride without improving the handling. Careful planning of modifications is a must, and Chapter 4 gives you ination on buy ing each new parL There is a suppliers list in the back of the book. In addition there are home-built modifications that can be of great benefit.
If you are a home craftsman, you can build such things as adjustable anti-roll bars which may not even be available for your car. It not only provides great satisfaction to build your own parts, but also can put you ahead of other drivers on the road. It is possible to have a really superior and unique car through modification. Stag 3 is one that few people should attempt This is designing your own chassfa. To put your ideas on paper is one thin , but it is entirely another to fabricat I the par ls and gel the en tire package assembled and tested to perfecti n.
In th s book I have supplied sufficient in a ion to attempt a design, but have not cov reel many of the related technical problem. Structmal strength and stiff ness is o e of these problems.
Unless you are a mechanical engineer. Another fundamental problem is fabrica tion tecl niques. Thfa parl of designing and building a complete chassis is best left to profe sionals. Very few productio11 cars arc a design failure i the sense that they dont do what the designer and factory inte11detl. Jrive are often unusual rivers or those who wanl the tar to do u usual things. Cornering well in. When y u change something, you have change the car to a different design.
Your de ign. Cha ng one part of the design often has far-reaching effects and it is rare that making a single change does anything good. Photo by Goodyear on their proving ground near San Angelo, Texas, shows the difference tires make to wet weather control. Because the discipline of looking dear to the end is vital in any modification program, the remainder of this chapter is a discussion of things the designer has in mind when he designs a racing cc1r.
There are a few technical terms used in th. Ir you happen not lo understand one or lwo or them, dont worry about iL now, because the main pu rposc here is to give you an overview of design procedure. All technical terms are carefully explained and defined in later chapters of this book, where Lhey are applietl to spcciric modifkations and improvements you can du.
Before putting paper on lhe drawing board a designer establishes his design crileria. This is a list of objectives and specifications for the racing car which will be guide and ground rules all through the design. Criteria are essential to having a finished product that is consistent in ail areas and meets the design objectives.
How many times have you seen a specially-built car that is lightweight in one area and super-heavy in another Criteria, if followed faithfully, will pre vent that sort of mistake. The criteria should answer these questions. Why are you designing the car rather than buying one What makes your design better than the ones currently win ning races What class will you compete in What length races wilJ the car be designed for What forcc-lo;1ding conditions are expected What specifications and per ance are you trying to beat The Jirst two questions deserve a good answer before starting a design.
