I also have this posted in the racing group but want as much info as I can get. Took the race car out for breakfast today. After leaving I was pulling out into traffic got straight and nailed the throttle. All was well, got home and notice the driver side of the car is sitting 3 or 4 inches lower than the passenger side.. Looking under the car the driver side leaf looks flat and the rear spring eye is all the way to the rear of the slider. What do you think happened, why and how to stop this happening again? Arched spring. Flat spring.
