How do you set up suspension in drag racing?
If the car gradually wheel stands or bounces violently, adjust front suspension first, then rear. If there is rear tire shake, wheel hop or excessive body separation, adjust rear suspension first, then front. After the car has been adjusted to launch straight, test launch and include the first gear change.
What is the best suspension for drag racing?
The most popular drag race rear suspension is the ladder bar combined with coilover shocks. This system entails a triangulated bar with two attachment points at the rear axle and a single connecting point at the chassis.
How do you adjust shocks on drag racing?
Turning counter-clockwise will stiffen the strut; turning clockwise will soften it. To set the extension baseline, turn the adjuster to full firm (once it stops, do not force it!), then turn it clockwise three to five clicks. The compression adjustment on the strut is on the base.
Do dragsters have suspension?
Dragsters were first built with their engines in front simply because their builders followed the front-engine standard of production cars. However, they did not use (and current dragsters still do not use) any form of suspension. Because of this, these types of vehicles were prone to becoming unstable at speed.
Is 4-link good for drag racing?
The 4-link suspension is the most common and proven setup among the many different classes in drag racing, but it also has its own limitations — namely in regards to adjustability. That’s where Rick Jones Race Cars and Quarter-Max come to the table.
How do drag racing shocks work?
QA1 shocks are a hydraulic twin-tube design that moves fluid throughout the shock when it extends and compresses. Turning the knob will either restrict this fluid travel or open it up. On the vehicle, this will result in a firmer or softer ride quality.
What are drag shocks?
“At base, the shocks in a drag car are controlling how hard the car is “hitting” the tire and how weight transfer is being achieved. Things like the rate of rise (wheelies), down track traction, and sixty foot times are all tied into the performance of the shocks on any drag car,” Saffell told us.
How does rear suspension work in drag racing?
They have a heavier spring rate on the passenger side than on the driver side, thus creating preload. Additionally, they are much stiffer in the front half of the spring (due to the axle not being centered on the spring) than the rear half, creating a rear suspension that works like a ladder bar setup.
What kind of springs are used in drag racing?
Mancini Racing used that race experience to grow into a parts business that sells suspension parts for Chrysler race cars. Whether you are using Chry-ler super stock springs or not, the ride height can be controlled by re-arching the existing leaf springs.
What makes a parabolic spring better for drag racing?
The Parabolic spring is a mono-leaf design that is thicker in the middle and tapers as it moves closer to the ends of the spring. This thinner leaf at the end allows the car to plant the rear tires quicker and harder.
What’s the best tuning for a Yamaha SRX 80?
Rpm,s may be different if a Dalton helix is not used. E XCELLENT SHIFTOUT OUT ANY LESS SPRING TENSION AND SECONDARY WILL SLIP. MAY HAVE TO TRY IT ON 80 WITH OTHER SRX’S THAT ARE STUDDED USE 6MM WASHERS TO TIGHEN UP BELT DEFLECTION. This set up works very well. Acceleration is much improved over stock.
How does the suspension work in drag racing?
You give it some gas, the front of the car comes up as weight is transferred to the rear tires to aid traction. That’s tied to suspension. The speed at which the front end rises is largely controlled by the spring rate and front shock force.
How can I tune my front shock for drag racing?
Tuning the front shock rebound and compression is a practice of observation first and then making adjustments based on how the car reacts. There is no magic formula for achieving a proper shock adjustment while the car is sitting still.
What kind of spring should I use for drag racing?
If you’re setting up a drag race-only front suspension, you can take the spring recommendation from our website and choose a spring that is one spring rate lighter to give you more stored energy,” Smith explains.
What makes varisprings suspension better for drag racing?
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 general terms, the worse a car hooks, the more shock extension travel it will need. If you need more extension travel, preload can be removed to lower ride height.
