Description
Push your 6th Gen Camaro to the front of the pack with the UMI 225558-1R Complete Race Coilover System. Designed specifically for road racing, time trials, and competitive autocross, this uncompromising four-wheel package delivers the grip and stability required for R-compound tires and heavy aerodynamics. The kit pairs UMI's premium 2024 aluminum front caster/camber plates and extreme-duty double-shear rear mounts with Viking Crusader GP-valve double adjustable dampers. Aggressive 450 lb/in front and 550 lb/in rear linear springs drastically reduce body roll, brake dive, and rear squat, keeping your tire contact patch planted under extreme lateral loads.
Built for 2016–2024 Camaro models, this direct bolt-on system offers massive suspension adjustability. The independent compression and rebound damping allows you to fine-tune weight transfer for any track surface, while the threaded shock bodies enable precise corner-balancing. UMI's front plates facilitate quick, engine-bay alignment adjustments—adding up to 1.25 degrees of camber and 1.75 degrees of caster. Track-tested at UMI Motorsports Park, this 100% USA-made kit is the ultimate foundation for serious competitive track builds.
Product Features
- Complete 4-wheel race coilover and mount kit
- Viking Crusader double adjustable dampers
- Aggressive 450 lb/in front & 550 lb/in rear springs
- 2024 aluminum front caster/camber plates
- Laser-cut double-shear rear upper shock mounts
- Bearing mount rear shock ends
- Engine bay front alignment tuning
- 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 Crusader dampers: Race-oriented double adjustable struts and shocks offer a massive adjustment range to support high spring rates and sticky tire compounds.
- Competition coilover springs: Stiff 450 lb/in front and 550 lb/in rear rates increase roll and pitch resistance, keeping the car flat under heavy braking and high-g cornering.
- 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 wheels. *(Note: Front toe alignment will need to be reset any time Caster/Camber is changed.)*
- Double-shear rear mounts: UMI 2258 brackets replace the weak factory single-shear setup, ensuring a rigid foundation for your rear coilover assembly.
- Bearing mount shock ends: The rear Crusader shocks feature bearing mounts to enhance pivot articulation and prevent binding under extreme suspension travel.
- Take-up spring kit: UMI auxiliary front springs ensure the stiff main springs remain properly seated when the suspension reaches full droop.
- Corner balance ready: Threaded shock bodies front and rear enable precise ride height adjustment, allowing you to establish perfect rake and corner weights.
- Track-proven validation: Extensively tested on the road course at UMI Motorsports Park to ensure reliable, national-level performance.
Product Outcomes
- Flattens cornering stance and severely reduces dive under threshold braking.
- Maximizes corner-exit grip by managing rear squat and maintaining an optimal tire contact patch.
- Allows rapid trackside damping and alignment tuning for changing track conditions.
- Eliminates suspension slop through spherical bearings and rigid double-shear mounts.
Installation Summary
Overview & Difficulty: Moderate DIY install requiring floor jacks, jack stands, and hand tools; 4–8 hours. Disassemble the front and rear suspension by removing factory struts, rear shocks, and coil springs. Install the UMI front plates and rear double-shear brackets into factory locations. Assemble the Viking coilovers (install rear bearing mount spacers per instructions; ensure rear shock bodies face up). Mount coilovers and torque to spec (front lower knuckle bolts 140 ft-lbs; rear upper bolts 70 ft-lbs). Magneride vehicles must disconnect the suspension harness and use a delete kit. Professional corner balancing and alignment are highly recommended. Please note that front toe alignment will need to be reset any time Caster/Camber is changed.

Product FAQ
Quick answers
Who is the UMI 225558-1R complete race kit intended for?
This complete four-wheel kit is built for serious 2016–2024 Camaro owners prioritizing road race, time trial, and autocross performance over street comfort.
How does the 1R race kit differ from the 1S street version?
The 1R uses race-oriented Viking Crusader valving and stiffer springs (450F/550R) to support heavy track loads, whereas the 1S uses Berserker valving and softer springs (300F/400R).
Will this system let me run aggressive camber settings for track tires?
Yes. The included UMI front caster/camber plates provide both caster and camber adjustment, giving you ample range to keep your tire contact patch flat.
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 setup.
Do I need to corner-balance the car after installing this kit?
Yes, corner-balancing is strongly recommended for competition use to fully leverage the four-wheel threaded coilovers and properly balance the chassis.
Do I need to remove my wheels to adjust the front alignment?
No. Trackside caster and camber adjustments are made from the engine bay with simple hand tools, saving valuable time between sessions. However, please remember that front toe alignment will need to be reset any time Caster/Camber is changed.
Does this kit require chassis modifications or welding?
No. The entire system features a direct bolt-on design using factory mounting locations and included Grade 8 hardware.
Is this setup suitable for street driving?
While it can be driven on the street, the 1R kit will ride noticeably firmer than stock and is best suited to cars that see frequent, aggressive track use.
