Hi José,
Please have a look at the file below:

The problem would be solved if the Spline Effector would use the results from the Step Effector. But since this Effector overwrites this results, we need to get this information first before it can be applied to the Spline.
To first place the clones on the spline and then use the Step Effector works after the spline was evaluated for position, hence the displace of the clones.
The file above uses the polygons as information source, hence the Polygon Center in the last Cloner setting. Since the Spline Wrap Deforms the objects, the Polygons are the ones that will be not rendered, but the polygon center stays pretty much the same, make them smaller if not. Since they influence the Bounding Box of the Spline Warp, I wouldn’t go larger at all.
A more straightforward method is given with the Matrix object, since it doesn’t share the deformation of the “clone” representations.

Let me know if that works for you.
All the best
