Real-world results

We have installed this spring set on customer G82s and our own vehicles. Feedback has been consistently positive, with drivers reporting a more planted chassis, improved confidence on B-roads and a clean, level stance without the harshness you get from budget options.

Lowering note

The stated height reduction is a guide. Actual drop can vary depending on vehicle specification, trim level and options. Cars equipped with factory sport suspension may see a slightly smaller change in ride height.
