Proper Suspension is Essential for Traction. that I have seen the rear shocks should never be adjusted less that half way that point. everything going on? If you are having trouble getting the front end to rise, you can soften shock rebound valving or change to a softer spring. I saved where he detailed the following sequence that you should watch for: "This should be the sequence of events seen on the video. After playing around with this mount for a while, I can see where you could It may take some work with spring rates and upper mount relocation to get the correct combination of vehicle ride height and front suspension travel for your application. An inch or two After the car has been adjusted to launch straight, test launch and include the first gear change. Have them fill the screen as much as possible without zooming. The car is now ready for fine tuning to optimize results. Part 2 – Pinion Angle. And, it will rise higher, transferring more weight as the center of gravity rises, further assisting traction. Due to differences in weight distribution, wheel base, tire size, and horsepower, not all vehicles leave the starting line in the same manner once their suspension has been optimized. Ideally the front end should rise in a controlled manner, just enough to keep the rear tires loaded, then continue the pass with smooth transitions at all times. If ET does not improve, return to previous settings. The launch is critical, and it makes sense to create an optimal environment for a solid start. If the spring gets too stiff, a very dangerous condition develops.

Here's how to make them work together to make you faster. Now this is a real old video, before Go Pro's were available so understand the video quality isn't that great but it did the job. When using lighter rate springs, preload must be added by screwing the lower spring seat upward. VariSprings features a very high strength steel that allows the spring to be wound more coarse then traditional springs, which makes the spring travel farther before coil bind. In suspension department I recalibrate the front shocks to 90/10 and rear shocks to 50/50. Part 5 – Ride Height. According to Chuck, each setup provides for a very different handling experience. car to unload?

No matter how many buddy's you have watching your car launch, you're not likely going to get a very good idea of what the car is doing without video. First, required settings for drag racing applications vary greatly depending upon vehicle weight, weight distribution, suspension geometry and travel, horsepower, and available traction. A few notes as we proceed: it is generally better to tune suspension according to improvements in ET’s (Elapsed Times) rather than for specific occurrences such as the amount of wheel stand. So I decided to try If the tires cause the front end to bounce upon landing, the shocks are too stiff. come up, and it gets on them again. While bringing up launch rpm, the car rises about 3" in rear. Available in two different levels of performance, these drag racing kits offer easy, bolt-in installation and seamlessly work with whatever OE component each piece attaches to. From all Begin with light acceleration and low speeds. Watching each of these events and at what point in time they occur gives you Mustang Drag Suspension Setup. Tuning 4 Link Rear Suspensions for the Drag Strip. Drag Racing Suspension & Setup for Type 1 Aircooled VWs. but if the wheelie bars are off left to right, you have to adjust them.

Notice how much more detail you can observe when you have time to observe Pay close attention to what is happening to the front end during launch. Try to include the Christmas tree in the video, at least the top bulbs. Draw an … Front 90/10 Drag Shocks (PN 40520, 40521): Maximum front to rear weight transfer for racing applications. It was amazing to watch. The information in this article, properly applied, may be able to keep you from breaking and/or crashing your car, or at the very least keep you from scaring the living daylights out of yourself (and/or your spouse, track personnel, or spectators at the track!)

Your goal is to eliminate all jerking or bouncing movements during launch and gear shifts. This will mean they will have to stand most likely about 10-12 feet or so behind and to the left of the drivers door. Upgrading control arms, springs, and adjustable dampers are going to be the foundation for your suspension. Then you will be able to tell if each side is preloaded the same. The suspension essentially prevents any compression travel, making the tire sidewalls the effective springs, and eliminating much needed damping that helps to stabilize the vehicle. Zooming in tends to magnify hand movement and results in a really shaky video. There is a standard progression of events that occur as a doorslammer launches. The higher the Frames Per Second your video camera can record, the smoother your slow motion video will be and quite possibly you may see something in a frame that would be missed by a slower camera. Increase shock rebound stiffness by one, then test again. You'll The RacingJunk Editors Minimal chassis movement makes if very difficult to visually tell if the bump or rebound needs to be decreased.
