Product Description

The RS-R N144S is a Super Down SUS lowering spring set engineered specifically for the 2016-2024 Infiniti Q50 3.0T Sport, Red Sport 400, and Silver Sport in RWD configuration -- featuring the V37 chassis with the firmer Sport-tuned factory suspension. The Super Down series is RS-R's more aggressive lowering option (vs the milder Down SUS line), delivering an authoritative 1.6" to 1.8" drop at both front and rear that closes the factory fender gap, lowers the center of gravity, and gives the Q50 a planted, motorsport-inspired stance that complements the car's aggressive sport-luxury styling -- particularly the Red Sport's 400-horsepower performance personality.

RS-R is widely regarded as the number-one aftermarket spring manufacturer in Japan, and these are authentic JDM springs designed in Osaka with deep consideration of the V37 platform's specific factory suspension geometry, shock dampening characteristics, OE spring rates, and ride height parameters -- engineered to deliver both performance handling improvements and ride comfort that complements (rather than compromises) the Q50's daily-driver mission. Spring rates are 8.93 kg/mm front and 3.67 kg/mm rear, working seamlessly with the OE shocks for a balanced sport setup. Critical fitment notes: this kit fits RWD Sport / Red Sport / Silver Sport trims only -- it does NOT fit AWD models, base / Premium / Luxe Q50 with non-sport suspension (use RS-R N122S), 2014-2015 Q50 3.7L, or Q50 Hybrid. Suspension alignment is required after installation. Backed by RS-R's 1-year manufacturer warranty.
