Default Problem with cells shape

Hi, I'm currently trying to mesh a Fsae car with Star Ccm+, but I have a problem with the volume mesh.
As you can see from the images, the cells on the curvature result in a strange shape on the top side of the undertray, while on the bottom side of the same part the surface is well approximated. I tried to add a custom surface control for this part, reducing the minimum surface size, but it just increased the number of cells without improvement of the geometry.
I cannot use polyhedral mesh due to limits on my pc power.
Any suggestions on how to get a better result?
