Description
Transform your 6th Gen Camaro's handling and stance with the UMI 225558-1S Complete Street Coilover System. Engineered for enthusiasts who demand sharp turn-in and acceleration stability without punishing ride quality, this four-wheel true coilover conversion pairs UMI's premium suspension hard parts with Viking Berserker double adjustable dampers. The system utilizes 300 lb/in front and 400 lb/in rear linear-rate springs to deliver responsive body control for back roads and weekend track days, while UMI's front take-up springs keep the main coils seated quietly during full suspension droop.
Designed specifically for 2016–2024 Chevrolet Camaro models, this direct bolt-on system provides massive adjustability. UMI's 2024 aluminum front caster/camber plates allow up to 1.25 degrees of camber and 1.75 degrees of caster adjustment right from the engine bay. In the rear, UMI’s robust double-shear upper brackets eliminate factory single-shear flex to safely support the coilover transition. Track-tested at UMI Motorsports Park and manufactured 100% in the USA, this kit is the ultimate dual-purpose handling upgrade. (Note: Magneride-equipped vehicles require a separate delete kit).
Product Features
- Complete 4-wheel Viking coilover system
- Viking Berserker double adjustable dampers
- 300 lb/in front & 400 lb/in rear springs
- 2024 aluminum caster/camber plates
- Double-shear rear upper shock mounts
- Independent engine bay alignment tuning
- Front take-up springs eliminate droop noise
- 100% bolt-on installation
⚠ Fitment Note: A MagneRide delete module is required when using Viking, Penske, or other aftermarket shocks when installed on vehicles equipped with factory MagneRide struts. This module bypasses the MagneRide system and eliminates error codes on the dash.
Detailed Features
- Viking Berserker dampers: Double adjustable struts and shocks provide independent compression and rebound tuning at all four corners for precise ride quality control.
- Street-biased coilover springs: 300 lb/in front and 400 lb/in rear springs deliver a firm, responsive feel ideal for performance street driving and occasional track days.
- Engine bay adjustments: UMI 2255 front plates allow up to 1.25 degrees of camber and 1.75 degrees of caster adjustments quickly without removing front wheels. *(Note: Front toe alignment will need to be reset any time Caster/Camber is changed.)*
- Double-shear rear mounts: UMI 2258 laser-cut brackets dramatically improve rear shock mounting strength over the weak factory single-shear setup.
- Take-up spring kit: UMI auxiliary front springs maintain main spring preload and reduce suspension clunking at full droop.
- Ride height adjustable: Threaded shock bodies front and rear allow you to lower the center of gravity and dial in the perfect stance or corner balance.
- Heavy-duty spherical bearings: Interference press-fit bearings in the front plates eliminate strut mount deflection for crisp, instant steering response.
- Direct bolt-on fitment: Installs into factory mounting locations without cutting or welding (Magneride cars require a delete module).
Product Outcomes
- Lowers ride height and center of gravity for a more aggressive, customizable stance.
- Improves overall handling balance, steering response, and rear traction.
- Adapts quickly from comfortable street cruising to firm track damping.
- Eliminates suspension slop through spherical bearings and rigid double-shear mounts.
Installation Summary
Overview & Difficulty: Moderate DIY install requiring standard and metric sockets, wrenches, an impact tool, floor jacks, and jack stands; 4–8 hours total. Involves removing factory front struts, rear shocks, and divorced rear coil springs. Install UMI front plates and rear double-shear brackets into factory locations. Assemble the Viking coilovers and mount them into the vehicle. Reuse front lower knuckle bolts (tap splines out gently, spin nuts only). Torque front lower bolts to 140 ft-lbs and rear upper bolts to 70 ft-lbs. Magneride-equipped vehicles require disconnecting wiring and using a delete kit. Professional alignment highly recommended. Please note that front toe alignment will need to be reset any time Caster/Camber is

Product FAQ
Quick answers
What vehicles does this complete UMI coilover system fit?
The 225558-1S kit is a direct fit for all 2016–2024 6th Gen Camaro models, providing a complete front and rear suspension overhaul.
Can I use this system on a daily driven Camaro?
Yes. This Street kit is specifically tuned for dual-purpose use, featuring 300 lb/in front and 400 lb/in rear springs paired with Viking Berserker valving for comfortable street manners.
Does this kit allow me to lower my ride height?
Yes. The included Viking front struts and rear shocks are fully threaded coilovers, allowing you to adjust ride height, perfect your stance, and corner-balance the vehicle.
How do the front caster/camber plates improve handling?
They allow both caster and camber adjustment directly from the engine bay using hand tools, eliminating the need to remove wheels for trackside tuning. Note that front toe alignment will need to be reset any time Caster/Camber is changed.
Why does the kit include rear upper mount brackets?
The UMI 2258 double-shear rear mounts replace the weak factory single-shear design, providing the required strength and rigidity to safely run a true rear coilover.
What adjustments can I make to the Viking dampers?
The Viking Berserker dampers offer independent compression and rebound adjustment at all four corners, giving you total control over ride quality and weight transfer.
Will I need to cut or weld my chassis to install this kit?
No. The entire system features a 100% bolt-on installation using factory mounting points and supplied premium hardware.
Will this fit cars with factory Magneride?
The hard parts will bolt on perfectly, but replacing the factory Magneride system requires a separate Magneride delete kit to prevent dashboard error lights.
