How to run more stagger?

If you only have one size of tire available you can try “ballooning” your tire to increase its size. Ballooning is accomplished by filling the tire with an excessive amount of air and letting it sit in the hot sun for a while. You will want to consult with your tire supplier as to what a safe amount of air will be for your tire to avoid serious injury. Hopefully you have different tire sizes available and won’t have to go through the extra effort. To help get the car to turn into the corner you will want to create less stagger in the front end and less cross weight overall. This can be done by simply increasing the left front tire pressure. If you have the capability of moving some lead around, get it over to the right side. Depending on how wet the track is you may want to move your rear tires to the right as well. You can accomplish this by using a 2” offset rim on the right side and a 4” offset on the left side. If you don’t have different offset rims wheel spacers are an option. If you have the opportunity to run a softer compound tire, a wet track is the time to use it. I like to use them on both rear tires. The shorter race will probably not burn it them off (if it is wet enough). I also use the softer compound on the left front tire at all times.

How many street stock races has Lee Christjohn won?

Lee Christjohn of Antigo, WI knows what it takes to win street stock races. Christjohn has been racing street stocks for 13 years and has amassed 74 feature wins and 4 track championships. Christjohn likes to get to the track early and get his car set up so he can watch the races. Heck, if you are paying 20 bucks to get into the pits you might as well enjoy the show! There is a little more to watching the races than checking out a buddy. Watching others could give you a clue as to what kind of changes the track is going through and what lines the fast cars are using. It is also important to pay attention to your tracks preparation between races. Do they water every three races or just before the first race of the night? These could all substantially change the way you set your car up for your race.

What is the LF pressure on a RR?

The tire pressures were: LF = 17psi, RF = 23psi, LR = 15psi and RR = 14psi. The RF was high and the RR was low on pressures. The fix was to try to change the tires around while repressuring the tires so that we could get front and rear stagger.

What type of suspension does a 1985 Monte Carlo have?

The car is a 1985 Monte Carlo and has the metric four-link rear suspension, a stock frame throughout and must use stock type springs in their original positions. Shocks must be mounted in the stock positions and the car must have all stock suspension parts. As in most "stock" classes, teams are allowed to trade stock pieces from other model year cars as long as the brand is the same. This class also runs large Hoosier racing tires all around, where as the street stock classes are only allowed one racing tire on the RF.

What does a high moment center do in a balanced setup?

We have discussed this concept for over four years now in Circle Track. A high moment center reduces the desire to roll, so if we don't soften the RR spring, the rear will be stiff and not allow compliance.

What is the LF of a RF spring?

After careful consideration, we installed the following springs: LF = 900, RF = 850, LR = 225, and RR = 175. The front reverse spring split with the softer RF spring helps corner entry and promotes front roll angle, while the reduced spring split in the rear facilitates the high metric moment center while not going too far to help control the rear roll.

How high should the Panhard bar be?

The Panhard bar, mounted on the left side of the chassis, should be at heights of 12 inches left and 8 inches right. Tire selection should include a little more siping to help dissipate heat, as the tires will begin to spin slightly coming off the corners. There will be less grip, but not to the point of going overly soft on the springs or introducing great amounts of rear steer to turn the car.

Why is zero rear steer important?

Zero rear steer is essential now because our dirt car will handle much like an asphalt car. The driver can drive straight into the corner, brake harder, and get back into the throttle sooner than at any other time of the day.

How much does a LF spring weigh?

LM: We will want to soften the setup a little more while the track is transitioning through this phase, and we need to reverse-split the front springs. We could continue to move weight up and to the right in the car to raise the CG about 1 inch and further decrease the left-side weight percentage. The LF spring = 375; RF = 350; LR spring = 185; and RR spring = 175.

What is dry slick?

Dry slick, a condition in which the track has lost considerable moisture and is now very dry and slick with little grip: 0.7 to 0.9 g's (The cars are now very slow in getting into and through the turns, and traction under power is very low. Small gains in mechanical grip can provide substantial gains in lap times).

What is the most difficult track?

The most difficult tracks are the ones in which the type of dirt or clay needs a lot of moisture in order for the track crew to be able to groom the track. A promoter will often plow up a track during the week preceding the event, water it throughout the morning of the event, and then roll it while still pouring water on it until practice time. From then on, unless it is watered again, the track will begin to dry out and go through several phases of moisture content.

How to soften a car's shocks?

It is time to soften the car, move weight over to the right, and lower the rear moment center more . Change the RF spring to a 750-pound spring and the RR to a 175-pound spring. Raise the rear ride height one more inch, move weight up and to the right in the car, and soften all of the shocks. Reduce the air pressure in the tires by 2 pounds all around.

What are the two types of dirt cars?

Let's use two of the most popular types of dirt car-a touring Late Model and a metric-style Hobby Stock car. For each type of car, we will set up for the six conditions listed above.

LEFT SIDE WEIGHT ON DIRT

I run a Metric chassis on dirt circle track. The front upper control arms can be relocated, but everything else, (front and rear) must have stock suspension mounting points. I have recently been experimenting with higher than average Left Side weight percentages, in an effort to use ALL the contact patches on my car.

Re: LEFT SIDE WEIGHT ON DIRT

I'll add my humble opinion to that of Bubstr & rkless in the True Trac thread and say your LS isn't going to help you. Not going to argue your tire patch goal, just your setup philosophy including apparent focus on ballast placement as the primary adjustment.

Re: LEFT SIDE WEIGHT ON DIRT

It's just my opinion, but I've seen LS weights up to 60% and you give too much to get a little forward drive out of the corners. The first concept you have to grasp, is handling is a matter of forces and all forces originate from the center of mass. They are modified by your roll centers, anti squat and anti dive.

Re: LEFT SIDE WEIGHT ON DIRT

I understand that there will be a point of diminishing returns. I think that I might be at that point. That is the reasoning behind my question.

Re: LEFT SIDE WEIGHT ON DIRT

It's been my experience that adding weight low and left when the track slicks off will give you more forward drive. Dry slick tracks were my forte when I raced the SE WI dirts tracks 30 years ago.
