Thou Will Taketh Tire Temperatures
Tire temperatures are your link to what goes on between the tire contact patch and the track surface. I find it difficult to make sound tuning decisions without tire temps. Tire temperatures should be taken religiously every time the car comes off the track-even after a race.

Thou Shall Determineth the Exact Problem
A handling problem can occur anywhere on the track. Is it corner entry, mid-turn or corner exit? Does it happen everywhere? If a problem occurs in one place, does it result in a different problem someplace else?
The classic example of this situation is corner-entry understeer that a driver over-compensates for at the exit of the corner, creating an oversteer condition. The driver says the car is oversteering, but the real problem is the corner-entry push. Adjusting for the oversteer will make the problem worse.

Thou Shalt Not Have a Suspension Bind
Suspension binds create an inconsistent handling situation. If a bind is present, it is just about impossible to properly tune the suspension. If the car does not respond the way you think it should to suspension changes, check for bind in the suspension. Checking for binds should be part of your routine setup process.

Thou Shalt Not Have a Dead Shock
A bad shock can be very difficult to feel. Check the shocks if you cannot get the chassis tuned effectively. Feel for a dead spot or lack of resistance in both rebound and compression.

Thou Will Set Thine Car up According to Driver Experience
often, the fastest setup for a given car is too aggressive for a driver without some experience. When the suspension is too stiff, especially the shock valving, it is difficult for the driver to feel what the chassis is doing. The car reacts too quickly for the driver to sense what is occurring.
Softer springs and shocks, while slower for the experienced driver, may be faster for the inexperienced driver.

Thou Shalt Not Try to Cure Handling Problems With only one Element
Any handling problem can be changed by adjusting several different parts on a car; it is ineffective to change only one or two items to improve the handling. Often engineers, whether their specialty be shocks, tires, springs, or whatever, will try to cure a problem by using what they know best.
This is often not the most effective way to solve a problem. It is important to look at the entire system as a whole, then make changes that suit the system best and offer the most favorable compromise.

Thou Shalt Not Make More Than one Change at a Time
While more than one suspension adjustment may be needed to cure a handling problem, it is always best to make only one change at a time. Make a change, and then go test.
Making more than one change at a time can produce results that are difficult to analyze. Which change helped, and did one change actually hurt?

Thou Shall Measure Accurately
Recording inaccurate measurements is as bad as not keeping records in the first place. This can lead to all kinds of problems.

Thou Will Carry a Consistent Fuel Load
Changing fuel load will always be a setup and tuning problem. As fuel is burned off, handling will change as the weight in your fuel cell changes. If you do not tune with a constant fuel load, your data will be inaccurate and the results misleading. No more than a two-gallon fluctuation is acceptable. One gallon is a better mark. Remember that each gallon of gas weighs about seven pounds.

Thou Will Establish Good Crew/Driver Communication
If the crew and/or driver are not sure of the concepts of tuning and are not clear about the language, all sorts of problems can occur. Everyone on the team needs to be on the same page.

Thou Will Control over-driving
If a driver is over-driving the track or car setup, most of the data, whether from the driver or tire temperatures, will be less than accurate. Over-driving not only abuses the tires, but also masks real handling problems.

Thou Shalt Not Make Changes Which are too Big
If a change is too big, it can cause handling problems that are worse than the ones you already have. On the other hand, a change too small can be difficult to detect by the driver or on the stopwatch. Big changes include altering more than two numbers on shock valving, more than 15 percent in spring or bar rate, more than two percent crossweight or more than a 1/4-inch change in ride height.

Thou Must Understand the Whole System
Understanding the whole system is very important. The key is to understand how any change affects the tire contact load and traction. Always thinking in terms of tire contact patch load and traction will help you focus on making the best change possible for the situation.

Thou Must Recognize Changing Track Conditions
Track conditions constantly change. The car may get faster during the day even though the lap times are slower, because the track may be slowing more quickly than the car is getting faster. If in doubt, return to the starting setup to see how the track has changed.

Thou Will Not Chase old Tires
At some point, tires get too hard to be fast. There is a point beyond which, no matter what you do, the car will not get faster. Chasing an old set of tires is ineffective.

Detta är vad en annan går igång på.
Det är endast ett budord jag inte fixar, nämligen tredje.

Followers of Volkswagenism have Ten (10) Commandments which to follow.

1 Thou shall gather at Volkswagen shows and events, and join with clubs and travel in with the packs.
2 Thou shall speak of Volkswagen several times daily and of a positive manner.
3 Thou shall enjoy the daily task involved in maintaining and clean one's Volkswagen.
4 Thou shall take interest in Germany. Interest in it's people and it's culture.
5 Thou shall spread the good gospel of Volkswagen, being of fine quality and dependability, to the blind man.
6 Thou shall learn, and take into study, Volkswagen's history and model line..
7 Thou shall stand up for the values and beliefs of Volkswagen - of company, employees, owners, and of fellow Volkswagenist.
8 Thou shall never pass another Volkswagen in distress. Love thy brother of both water and air.
9 Thou shall try to make one pilgrimage to Wolfsburg in one's life. By one's self or of representation.
10 Thou shall love thy Volkswagen. Even if the child is sick, one shall love that child no less. Shower it with the gifts of custom accessories.


--------------------------------------------------------------------------------

It is important to remember that air cooled and water cooled children are of the same father, Volkswagen. Do not make borders between each. We must travel with and among each other in harmony. To become a true Volkswagenist one should follow these commandments of life. On the road of life, there are owners and there are followers.
