SUMMARY

The discussion focuses on the advantages and disadvantages of spring mount locations for a 2550 LB asphalt modified race car. Specifically, having the left rear spring in front of the rear end and the right rear spring behind the rear end can influence spring wrap under acceleration. The use of a decel/acel push/pull bar is also highlighted as a method to improve traction off turns, particularly with a torque output of approximately 600 lbs from the engine. The conversation emphasizes the importance of adjusting suspension angles, such as setting the acceleration at 14 degrees down and deceleration at 5 degrees up, to optimize performance.

PREREQUISITES
  • Understanding of race car suspension dynamics
  • Knowledge of torque link systems
  • Familiarity with spring wrap effects in racing
  • Experience with suspension angle adjustments
NEXT STEPS
  • Research the impact of spring mount locations on traction in asphalt modified racing
  • Learn about the function and tuning of decel/acel push/pull bars
  • Investigate the effects of suspension angle settings on race car performance
  • Explore advanced techniques for improving bite off turns in racing
USEFUL FOR

Race car engineers, suspension tuners, and competitive racers looking to enhance traction and performance in asphalt modified racing.

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!

Pls post on race car suspension class so we can use as teaching point
Pls include type car type of track
Track size , banking
Etc
See you there

ok I will post tonight

Thanks
