RC Car Front and rear ride heights.


The rear ride height of a RC car can have various effects, and the optimal setup often depends on specific track conditions, the car's weight distribution, and other tuning factors. Here is what happens generally when you raise or lower the rear ride height:

Lowering Rear Ride Height:

  1. Increased Traction: Lowering the rear usually increases traction by lowering the center of gravity. More weight is transferred to the rear tires, giving better grip during acceleration.
  2. Improved Aerodynamics: A lower ride height decreases aerodynamic drag, which is beneficial in drag racing where high speeds are reached very quickly.
  3. Enhanced Stability: A lower center of gravity makes the car more stable during rapid acceleration, helping to keep it in a straight line.
  4. Reduced Weight Transfer: Lowering the rear ride height reduces the dynamic weight transfer to the front wheels, helping the rear wheels maintain better contact and therefore better traction.
  5. Risk of Bottoming Out: Too low a rear ride height could lead to the chassis hitting the ground, causing friction and slowing down the car.
  6. Limited Suspension Travel: Lowering the ride height too much could limit the range of the suspension travel, making the car less forgiving on bumpy tracks and potentially affecting performance.

Raising Rear Ride Height:

  1. Reduced Traction: Raising the rear usually results in reduced traction at the rear wheels due to a higher center of gravity and less weight being transferred to the rear wheels.
  2. Increased Weight Transfer: A higher rear ride height will tend to transfer more weight to the front wheels during acceleration, which may result in wheelies or reduced rear-wheel traction.
  3. Decreased Stability: A higher center of gravity can make the car less stable, especially during rapid directional changes or acceleration.
  4. Increased Aerodynamic Drag: A higher rear end will generally catch more air, increasing drag and potentially slowing down the car.
  5. Improved Ground Clearance: On the positive side, raising the rear ride height will give you more ground clearance, making it easier for the car to go over bumps or irregularities in the track without bottoming out.
  6. Changed Drive Shaft Angle: In some designs, raising the rear ride height can affect the driveshaft angle, potentially leading to wear and tear or inefficient power transfer.
  7. Variable Handling Characteristics: A higher rear end may make the car handle differently in corners, although this is less of an issue in drag racing, which primarily involves straight-line speed.

So, when adjusting the rear ride height, you should consider all these factors to optimize your RC car's performance for drag racing. Fine-tuning this setting while testing the car on the actual race surface is the best way to determine the optimal ride height for your specific circumstances.


The ride height of the front end of a RC car is as critical as the rear and affects several aspects of the car's performance. Adjusting it can lead to various changes in how the car handles. Here's how:

Lowering Front Ride Height:

  1. Increased Front Traction: Lowering the front ride height can increase the weight and pressure on the front tires, improving traction and steering responsiveness.
  2. Reduced Aerodynamic Drag: Lowering the front reduces the aerodynamic profile of the car, which can improve speed over short distances typical of drag racing.
  3. Enhanced Stability: Lowering the front ride height reduces the center of gravity, which generally makes the car more stable, especially during rapid acceleration.
  4. Reduced Weight Transfer: A lower front ride height may help in controlling the weight transfer to the rear, ensuring that not too much weight shifts backward, which would otherwise reduce front-wheel traction.
  5. Risk of Bottoming Out: Just like with the rear, if the front ride height is too low, the car risks bottoming out or scraping against the track, potentially damaging the car and affecting its speed.
  6. Limited Suspension Travel: A lower front ride height also reduces the suspension's range of motion, which might be detrimental when the track has irregularities, although this is generally less of a concern in drag racing compared to other types of RC racing.

Raising Front Ride Height:

  1. Reduced Front Traction: Raising the front ride height reduces the weight and pressure on the front tires, potentially decreasing traction and making the steering less responsive.
  2. Increased Weight Transfer to Rear: A higher front ride height can help shift more weight to the back wheels during acceleration, potentially increasing rear-wheel traction but at the expense of front-wheel traction.
  3. Increased Aerodynamic Drag: A higher front end will usually catch more wind, leading to higher aerodynamic drag and slower speeds.
  4. Decreased Stability: Raising the front end will generally make the car less stable and more prone to tipping or flipping due to a higher center of gravity.
  5. Improved Ground Clearance: On the plus side, a higher front ride height provides better ground clearance, making it easier for the car to manage bumps or irregularities in the track surface without bottoming out.
  6. Variable Handling Characteristics: Like a higher rear end, a higher front end changes the car's balance and may affect how it handles during the brief moments when steering inputs may be needed in a drag race.

Given these factors, setting the optimal front ride height often involves a trade-off between traction, stability, and aerodynamics. The best ride height setting can also depend on other variables like tire type, track surface, and overall car setup. It is advisable to experiment with different settings and conduct tests to find the most effective setup for your specific RC car.
