Rear Spring Advantages/Disadvantages for 2550 LB Asphalt Modified

[mikey531]

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!
