Detroit Speed - Archived Suspension Kit - 154003-373-SDS

The Detroit Speed Level 2 Full Vehicle Kit captures the essence of a true DSE build - refined ride quality on the street with confident, track-ready capability. Designed for C2 and C3 Corvettes producing up to 800 horsepower, this system combines modern geometry, single adjustable coilovers, and the proven ZR12 IRS Differential. Ideal for enthusiasts who demand versatility, the Level 2 makes the transition from weekend cruising to spirited track driving seamless and controlled. ENGINEERED FOR MODERN HANDLING & TRACK CAPABILITY Elevate your Corvette into a true dual purpose performer with the Level 2 - Detroit Speed’s premier suspension integration engineered for precision on the street and dominance on the track. At the front, the SpeedRay™ system introduces a fully engineered coilover conversion, crisp rack and pinion steering, and premium Corvette hub pack uprights. This bolt in assembly reshapes suspension geometry for sharper turn in, reduced body movement, and a planted feel that inspires confidence whether carving backroads or attacking apexes. The DECAlink™ rear suspension completes the package with its true multilink architecture and coilover conversion - delivering exceptional stability, traction, and ride quality. The included CV axle kit ensures a factory clean interface with the ZR12 IRS Differential (selectable in 3.55, 3.73, or 4.11 ratios). To tie it all together, tuned, single adjustable coilovers allow effortless transitions from compliant street manners to track ready precision. With predictable balance, improved feedback, and remarkably refined ride quality, this Level 2 package elevates your Corvette to a new level of modern performance - any road, any track, any time.

Note: LEVEL 2 TUNABLE PERFORMANCE, STREETABLE CONFIDENCE The Detroit Speed Level 2 is built for the enthusiast who wants a sharper edge and the ability to dial the car in. It bridges the gap between refined street driving and true performance tuning, giving you more adjustability and a more responsive feel without pushing the build into full competition territory. Level 2 is about control you can tailor. Ride height, stance, and overall response can be set to match your wheel and tire package, driving style, and the way you want the vehicle to behave. The result is a chassis that feels more immediate on turn-in, more stable through transitions, and more planted when you start leaning on it. It keeps street usability in mind. You get the tuning capability to chase a more aggressive setup, but with the composure to drive it often. It is the right choice when you want something beyond a set-and-forget package, and you enjoy the process of fine-tuning the way the vehicle feels. If you want modern performance with the freedom to make it yours, Level 2 is where Detroit Speed engineering meets driver preference.
