Weldineer stated correctly (below) that the anti squat reaction to the torque of the axle lifts the mass of the vehicle resulting in an increase in downward force on the tires. Instant Center Lenth: 52. Occasionally the driver might report that the front wheels feel light under acceleration at the late apex point – if so you should dial back the top link angle and anti-squat for driver feel. The AntiSquat value is 111. With stiff suspension and shock valving and an engineered low CG, there is little need for it to control torque and weight transfer induced squat. anti squat is a term used with rear wheel drive cars and is the amount of compression that is applied to the drive wheels under acceleration. This photo shows a 2 deg.

Anti-squat prevents the rear end from compressing or “squatting” during acceleration (and with very large angles actually causes the rear chassis to rise up somewhat). What percentage of anti-squat that is necessary is going to vary from application to application (not necessarily 100%) but in general - vehicles set up for drag racing run high percentages of anti-squat. Jun 22, 2009 · Page 1 of 2 - anti-dive - posted in The Technical Forum Archive: Do we like anti-dive or anti-squat?

You want to shock the tires as in anti squat (4 link term) to get them to firmly plant without unloading and causing spin. As a car accelerates forward, weight transfer causes the rear suspension to squat. Where do you wheel? Highlights in this issue include insights into torque converters, parachutes, and brakes. You could argue that not having very much anti and running stiffer springs would accomplish the same goal and might work better, but again, case by case Forward acceleration anti-squat is calculated in a similar manner and with the same relationship between percentage and weight transfer. In drag racing, a chassis that exhibits this has 100% or greater rear anti-squat suspension geometry. I am not too concerned with ride quality on the street, but my main concern is solid 60' and 1/4 mile times. 0/4. The biggest advantage to a four link is it’s adjust-ability.

Performance Trends computer program to simulate and analyze rear suspension 4-link setups for instant center, pinion angle and driveshaft angle change, anti-squat percentage, and more for drag racing. With the design of the Mustang’s rear suspension (short upper arms, longer lowers), the geometry changes somewhat with ride height. and that problem is only exacerbated when drag racing or sticky tires are part of the plan. People who sell 4-bar linkage kits for drag racing your muscle car will tell you to move the linkage from ~100% anti-squat for racing to 0% for regular driving by making the linkage parallel and level. the chassis and suspension links take 100% of the load. Street or a pair of slicks, moving the instant center rearward will apply more leverage to the rear suspension, reduce the squat Re: Caltracs - install, set up, tuning August 27th, 2012, 06:50 AM I would aim for 100% anti squat to start with on a bias tire ( no rise or squat from the rear) or as close as you can with the mounts you used, or on a radial 120%.

S550 Mustang IRS – Independent Rear Suspension (IRS). 8″ solid axle rear end, incorporates adjustable anti-squat, and is best for drag race set-ups. “And it’s really the only application that it So you'll see much less aggessive IC locations and even anti-squat numbers of less then 100% in higher HP big tire slick cars. im green at this so bare with me, i know there are alot of different things to consider , but. We like to run a rear anti-roll bar where possible ie if limited slip diff is fitted, because this allows the use of softer rear springs. anti-squat angle on the rear of an RC10B4. Now if your 'Instant Center' falls ABOVE your '100% Anti-Squat Line', you will have more than 100% Anti-Squat. Hopefuly some people will devulge their secrets. Mar 12, 2015 · Having spent most of my years drag racing in muscle cars with coil springs, I decided to contact John Calvert (from Calvert Racing Sus-pensions) to get some ideas on the latest technology in making rear-wheel-drive cars with leaf-spring rear suspensions hook, even though the same old issues still exist of setting pinion angle, preload, getting Apr 23, 2015 · The neutral line (examined previously) slopes within the car from front to rear. BENOIT: Suspension kinematics are a mix of many factors including Anti-Squat, Axle Path, Leverage Ratio, and Frame Design (Clearance, shock placement, geo, and frame stiffness). Come join the discussion about racing, builds, pro mods, hot rods, events, turbos, nitrous, superchargers, and more! Aug 23, 2019 · Primary driver behind weight transfer is acceleration force acting on the cars weight, wheelbase, and cog. Anti-squat is a transient vehicle suspension parameter which can dramatically affect tractive effort available at the motorcycle drive tire. But first we have to locate our ’100% Anti-Squat Line’. If the inner hingepins are flat (parallel to the ground) or have no angle, then the vehicle has zero degrees of anti-squat. Drag Radial Rear Suspension Explained, I/C Anti-Squat & More!

Installed with either design of our lower control arms and anti-squat brackets, the new TorqueArm geometry eliminates rear wheel hop while at the same time greatly improving forward bite and launch performance as well as chassis stability while driving at the limit in situations causing ride height changes as in cresting a hill while cornering. According to Zimmerman, anti-squat effects how violently the suspension “hits” the rear tires on launch. He did not mention clearance issues associate with the typical squating most trucks do since they do not run an anti squat system. Draw a line from the tire contact patch through the Instant Center: this is the tire force vector. 4-Link settings with less than 100% Anti-Squat are likely to squat under hard acceleration (rear of car drops), and "hit the tires more softly".
