Toe adjustment after spring change: is it necessary?

Toe adjustment when changing the chassis spring, shock absorber or top mount Clear answer: yes.

Installation work on the chassis, be it a spring change, a replacement of the shock absorbers or a change of the dome or strut support bearing, changes the setting of the suspension.

This is not always immediately noticeable. You may later find out after several thousand kilometers that the tire tread has worn out unevenly. Then it will be too late!
To ensure that the tires do not wear out excessively or unevenly, it is highly recommended to readjust the track and, if necessary, the camber of the wheels after installation.
