Start here if you're new to coilovers, spring rates, damping, and the fundamentals of how suspension geometry affects ride quality, handling, and vehicle dynamics.
← Back to Tech HubSuspension can seem complicated — coilovers, springs, damping curves, preload, ride height, motion ratios, and more. This section breaks down the fundamentals in clear, practical language so you can make informed decisions and tune your Dežru setup with confidence.
Why you don't match perch measurements, how to measure at the pinch weld, and when to consider corner balancing.
Understanding stiffness, wheel rate vs spring rate, motion ratios, and how to choose the right spring rate for your driving style.
What preload actually does, when to use it, how helper springs work, and why preload does NOT raise or lower the car on fixed-length assemblies.
A clear breakdown of compression, rebound, valving curves, and how damping affects both comfort and performance.
What causes each, how spring rates and damping contribute, and how to tune your Dežru setup for a more neutral balance.
How wheel rate is calculated, why spring rate doesn’t tell the whole story, and how motion ratios influence handling and spring selection.
