I have a bracket car with the Calvert springs.
It's a 7.0 1/8 mile car.
Thought I had a problem with them once, this car sees a lot of racing & I thought they were worn.
Before I tore it apart, I purchased new rear segments, same as what was on the car.
When I tore it down, found a spring perch had broken loose from the weld.
Went ahead & put the new rear segments in.
Found the car sat 1" higher with the new segments.
So, I guess they can wear some over time.
