If you own a Backdraft Racing Cobra replica, you know that proper suspension is key to both handling and safety. Over time, original components wear out, or you may want to upgrade for better performance. This guide covers the most important new suspension parts available for Backdraft cars, what to look for, and how to make smart choices.
Understanding Backdraft Suspension Systems
Backdraft uses a combination of front and rear suspensions inspired by the original AC Cobra but with modern improvements. The front typically uses an independent setup with upper and lower control arms, coilover shocks, and an anti-roll bar. The rear often features a solid axle with leaf springs or a three-link setup, depending on the model year and trim. Knowing your car’s specific configuration is essential before ordering new parts.
Key Components That Need Replacement
- Shocks and Struts: The most commonly replaced wear items. Upgrading to adjustable coilovers can dramatically improve ride quality and cornering.
- Control Arms and Bushings: Rubber bushings degrade, causing alignment issues and noise. Polyurethane or spherical bearings offer longer life and sharper response.
- Sway Bars: Larger-diameter bars reduce body roll. Many aftermarket options are direct fit.
- Springs: Coil springs can sag over time. New springs matched to your driving style (street, track, or show) are available.
- Steering Components: Tie rod ends, ball joints, and steering racks should be checked and replaced if loose.
Top New Suspension Parts for Backdraft
Coilover Kits
Coilover shocks replace the factory strut and spring assembly. Brands like QA1, Viking, and Penske offer adjustable damping and ride height. A typical kit includes front and rear shocks, springs, and hardware. Benefits include improved handling, adjustability, and often a lower stance. For street use, a single-adjustable shock (rebound only) is sufficient; for track use, dual-adjustable (rebound and compression) provides more fine-tuning.
Control Arms and Bushings
Replacing factory control arms with tubular aftermarket units reduces unsprung weight and allows for better geometry. Many come with polyurethane or heim-joint bushings that never need replacement. Look for arms with TIG welding and chrome-moly construction for strength. Some brands offer adjustable length for fine-tuning camber and caster.
Sway Bars
Upgrading the sway bar is one of the cheapest and most effective handling improvements. A 1-inch diameter bar is common for street use; 1.125-inch for track. Ensure the bar comes with polyurethane bushings and end links. Backdraft-specific bars from companies like Hellwig or Addco are direct bolt-ons.
Spring Upgrades
If you want a different ride height or rate, aftermarket coil springs are available by the inch-diameter and spring rate. Companies like Hyperco and Eibach offer springs in various rates (200-500 lb/in for front, 150-300 for rear). Choose based on your car’s weight distribution and intended use. Softer springs for street comfort, stiffer for track.
Compatibility and Fitment Considerations
Backdraft has evolved over the years, so not all parts are interchangeable. Always confirm your car’s year and chassis number. Common variations:
- Chassis Dimensions: Early cars may have different shock mounts and control arm lengths.
- Brake Clearance: Wilwood or Baer brake upgrades may require specific wheel offsets or spacers.
- Steering Rack: Manual vs. power steering racks affect tie rod ends and mounting.
When in doubt, call the manufacturer or a Backdraft specialist. Many part numbers are available on manufacturer websites, but it’s best to verify with a knowledgeable source.
Installation Tips for New Suspension Parts
- Safety First: Use jack stands, never a jack alone. Suspension bolts may be tight; use penetrating oil and a breaker bar.
- Torque Specs: Always tighten bolts to manufacturer specifications. Many suspension bolts require final torque with the car on the ground (under load).
- Alignment Required: After any suspension change, get a professional alignment. Toe, camber, and caster settings affect tire wear and handling.
- Grease Fittings: If you install polyurethane bushings, use a dedicated grease gun to prevent squeaks.
Performance vs. Comfort: Making the Right Choice
Your driving style dictates the best parts. For daily driving and weekend cruises, focus on quality shocks (like Bilstein or Koni) and low-maintenance bushings. For autocross or track days, invest in adjustable coilovers, stiffer springs, and spherical bearings. Remember that stiffer parts can be harsh on rough roads. A good middle ground is a monotube shock with adjustable damping and polyurethane bushings.
Final Recommendation
For most Backdraft owners, a solid upgrade path starts with replacing worn bushings and shocks. If you’re on a budget, focus on the front control arm bushings and a set of quality shocks (e.g., Koni Sport or QA1 single-adjustable). For a more comprehensive improvement, a full coilover kit from QA1 or Viking with matching springs and sway bars will transform the car’s behavior. Always buy from reputable suppliers who know Backdraft specifications. Take your time researching, and don’t hesitate to ask for advice on Backdraft owner forums.
