Car weight distribution: understanding its effects when driving on track Track driving advice around front-wheel drive and rear-wheel drive weight distribution plus an introduction to your tyres

  • Free rulerEven though the weight at each corner changed in this example, the weight distribution remained unchanged because you are still standing in the middle of the table. About this time, many racers give up on trying to understand weight distribution and cross weight. Adding weight to the car actually reduces the relative amount of traction compared with the total weight of the vehicle. For example, say a 3,000-pound car makes 3,000 pounds of cornering force at the limit. That’s 1 g of lateral force. Let’s say we add 500 pounds to the car with nothing else changed, including the weight distribution.
  • If you're guessing blindly, use a 55%/45% weight balance; however, it is much more appropriate to measure your car. Example corner weight using weight balance: To get the corner weight of your car, take an example total weight of 3800 lbs and multiply it by the front end weight bias. ex: 3,800 x 55% (front end weight balance) = 2,090.
  • Machine learning regression week 2When more than 50 percent of the car's weight is on the left-rear and right-front wheels, the car is said to have more wedge. ­Now that we've learned how an adjustment on one corner of a vehicle can affect the weights on the other three corners, let's take a look at how this uneven weight distribution affects a race car's handling.

Weight Distribution Calculator. Enter the four weights of each wheel in the boxes below and click on Results! Weight transfer is a function of car weight, CG height, wheelbase, and acceleration. The only way a suspension adjustment can affect weight transfer is to change the acceleration. Naturally, you're more inclined to wheelstand with an increase in acceleration. To "fix" this with a suspension adjustment is simply to reduce acceleration. May 09, 2014 · A-Arm Suspension System for Chassisworks 4×2″ Crossmembers and Front Clips. This is the first of a three part series from Chris Alston’s Chassisworks on tuning and calibrating for better drag race performance. Car Corner Weight, Wedge and Cross Weight Calculator. By Rob Robinette. This calculator takes your car's four wheel weights and calculates current weights and percentages and generates target wheel weights to achieve a 50% Cross Weight or Wedge.

The car weighs 3000 pounds, and this means I might save 20 pounds of weight and 1/2 horsepower lost to spinning that weight over the length of the track. $400 is not a good investment at all for 1/2 horsepower over the length of the track, or the extra 1/2 horsepower applied for 11 seconds I have to extract at the end and convert back to heat ... Add weight nearly anywhere simply by filling this weight bar with lead pellets or shot. Made from 2" x 3" rectangular tube, this 14" long weight bar comes completely welded with welded bung, aluminum cap, and bolt sleeves for mounting. Bind rune healthThe Touring car in the middle likely has a 3.0-3.5Hz suspension frequency with it's simple aero package and race tires, while the F1 car will have a frequency in excess of 5.0Hz, as its downforce produced and ultimate grip level is far greater. The bike will run off the same principles as a car's suspension. Drag Race Baseline: 40-percent Bump, 60-percent Rebound Drag race vehicles generally require more extension (rebound) travel to help weight transfer, and because the drag strip is very flat, less compression travel is needed. The amount of extension travel available in the shock will drastically affect how the car works. The weight distribution of a typical 3000 lb car is 1600lbs front and 1400lbs rear. The truck weighed 3620lbs and the weight distribution was 2600lbs front and 900lbs rear! Decision: The PR was left at 59% because it already shocked the tires plenty hard with the N2O and T-brake.

This is the first of a three part series from Chris Alston’s Chassisworks on tuning and calibrating for better drag race performance. Jun 16, 2012 · Every car has some percentage of its weight that is carried by the front tires, and the rest by the rears. Because the cornering balance of a car is a strong function of that weight distribution, it has a major influence on how well the car will handle, and how fast it can go around a race track. The ultimate aim of weight distribution is to try and get a perfectly set up car, which is balanced during cornering in both directions and maximises equal loads through the tyres as much as possible. Unequal weight distribution, can result in a tyre or set of tyres being overworked, this can exceed the tyres overall grip levels.

It's more about inside / outside weight distribution ratio on a bike for bends. Weight forward under hard acceleration to keep the front down. In a car the weight is mainly inside the wheelbase, and is not dynamically changing much in comparison to a bike, hence best to spread the available grip equally. _____ X-Weight is a cross-weight calculator for 4-wheeled vehicles. I wrote it during my kart racing days to help with properly setting up weigh distribution. It is a It is that simple. If you are talking about ideal weight distribution in regards of driving dynamics and overall ‘handling’, then a 50/50 weight distribution is ideal. You used race cars as examples for why 50/50 weight distribution is not ideal. This logic is flawed. The engineers make these cars rear-biased so improve acceleration. Performance and race cars may have spring rates of 300, 400, 500 lbs/in and higher. Corner balance becomes much more important due to the high spring rates – small changes in height greatly impact weight carried.
