Set the perfect stance for daily driving, photo shoots, or track days, then restore stock height anytime. No permanent wiring or coding: plug in, adjust, unplug. Requires the LayMatic OBD-II dongle (sold separately). What you can do Lower in seconds: Easy Mode adjusts all four corners; Front/Back controls axles; Manual enables per-wheel fine-tuning. Save & restore: Your vehicle’s original values are backed up on first connect so you can return to stock anytime. Multiple vehicles: One Key licenses one car; add additional Keys to enable more cars in your garage. Non-invasive setup: No cutting, no “lowering links,” and no permanent wiring.
