In summary, the rear spring of a 2550 LB asphalt modified car has both advantages and disadvantages. The main advantage is that it allows for better weight distribution, leading to improved handling and cornering. However, a stiffer spring can also create a harsher ride and decrease traction. Additionally, adjusting the rear spring can be complicated and time-consuming, making it a disadvantage for some drivers. Overall, the choice of rear spring for a 2550 LB asphalt modified car depends on the driver's preferences and the track conditions.

We are racing a 2550 LB asphalt modified. What are the advantages and disadvantages of having the left rear spring in front of the rear end and the right rear spring behind the rear end? We also have a decel/acel push/pull bar on the center of the rear end. Approximately 600 lbs of torque from the engine.

Thanks

welcome...nice to meet a fellow racer..short answer is spring mount location can help a little bit on spring wrap under acceleration..torque link is to dial in hook up under acceleration as well..long answer is both questions are addresses in above post

Thanks I have read the posts and the big problem we have seems to be traction off the turns. The third link is supposed to increase bite off but they have tried it with staggered springs. Here is the info.

We have the accel set at 14 degrees down and the decel at 5 degrees up I think. I will have to double check the angles.

Thanks for the info above!

1. What are the advantages of using rear springs for a 2550 LB Asphalt Modified car?

One of the main advantages of using rear springs in this type of car is improved handling and control. Rear springs provide better weight transfer, allowing for more even distribution of weight during turns and acceleration. This can result in faster lap times and a more responsive and stable car on the track.

2. Are there any disadvantages to using rear springs in a 2550 LB Asphalt Modified car?

While there are many advantages, there are also some potential downsides to using rear springs. One drawback is that they can be more difficult to adjust and fine-tune compared to other suspension components. Additionally, rear springs may wear out faster than other parts of the suspension system, requiring more frequent maintenance and replacement.

3. How do rear springs affect the overall performance of a 2550 LB Asphalt Modified car?

Rear springs have a significant impact on the overall performance of a 2550 LB Asphalt Modified car. They play a crucial role in weight transfer, which affects handling, traction, and stability. By properly tuning and adjusting rear springs, drivers can improve their lap times and achieve better overall performance on the track.

4. Can different types of rear springs be used in a 2550 LB Asphalt Modified car?

Yes, there are various types of rear springs that can be used in a 2550 LB Asphalt Modified car, including coil springs, leaf springs, and torsion bars. Each type has its own unique characteristics and can be adjusted to achieve different handling and performance outcomes. It is important to choose the right type of spring for the specific needs and goals of the car and driver.

5. How can I determine the appropriate spring rate for my 2550 LB Asphalt Modified car?

The appropriate spring rate for a 2550 LB Asphalt Modified car will depend on a variety of factors, including the weight and weight distribution of the car, the track conditions, and the driver's preferences. It is best to consult with a professional mechanic or suspension specialist to determine the ideal spring rate for your specific car and racing goals.
