The Complete Guide to 2G DSM Suspension Parts

If you own a second-generation DSM — the 1995-1999 Mitsubishi Eclipse, Eagle Talon, or Plymouth Laser — you know these cars handle well from the factory, but after two decades, the original suspension is likely tired. Replacing or upgrading suspension parts can transform the driving experience, whether you're daily driving, autocrossing, or building a drag car. This guide covers everything you need to know about 2G DSM suspension parts, from common wear items to performance upgrades, without the hype.

Understanding Your 2G DSM Suspension Layout

The 2G DSM uses a MacPherson strut front suspension and a multi-link rear suspension. The front has struts, springs, sway bar, and control arms. The rear uses a trailing arm with lateral links, a strut, and a separate coil spring. Many parts are shared between Eclipse, Talon, and Laser, but there are differences between turbo and non-turbo models, as well as between ‘95-‘96 and ‘97-‘99 years.

Common Wear Items to Replace

Struts and Shocks

The original struts are usually worn by 80,000 miles, causing bounciness, poor handling, and excessive nose dive under braking. Factory replacement struts are available from Monroe and KYB, but many owners upgrade to adjustable struts like Koni Yellow or Tokico HP (now discontinued). For the rear, the strut is separate from the spring, so you can replace the strut cartridge without changing the spring.

Springs

Over time, springs sag, especially on turbo models. Stock spring rates are about 138 lb/in front and 118 lb/in rear for turbo cars. If you want a lower ride height and stiffer rates, aftermarket springs from Eibach, H&R, or Tein are popular choices. Avoid cheap no-name lowering springs that can cause bottoming out or poor ride quality.

Sway Bar End Links and Bushings

The factory plastic end links wear out quickly, causing clunking noises. Replace with metal end links from Energy Suspension or Moog. Also upgrade the sway bar bushings to polyurethane for better response.

Control Arm Bushings

Front lower control arm bushings are a common source of slop. After 100k miles, the rubber bushings crack and allow the arm to move, affecting alignment. Replace with polyurethane bushings or buy new control arms with pre-installed bushings.

Rear Trailing Arm Bushings

The rear trailing arm bushing is another weak point. Worn bushings cause the rear to feel loose during cornering. Polyurethane replacements from Energy Suspension or Prothane are affordable and easy to install.

Performance Upgrades

If you plan to track your car or just want sharper response, consider these upgrades beyond stock replacement.

Coilovers vs. Strut and Spring Combos

Coilovers like BC Racing, Fortune Auto, or Feal allow adjustable ride height and damping. They are a popular choice for serious autocrossers and street drivers who want a lowered look. For a simpler setup, a matched set of lowering springs and Koni Yellow struts is a proven budget option that handles well.

Adjustable Camber Plates

2G DSMs have limited camber adjustment from the factory. Adding adjustable camber plates on the front struts gives you the ability to dial in negative camber for cornering or positive for drag racing. This is essential if you lower the car significantly.

Sway Bars

Upgrading to larger diameter sway bars, like those from Addco or Suspension Techniques, reduces body roll. Pair with polyurethane bushings for best effect. You can run a bigger front bar or a combination of front and rear bars.

Subframe Bushings

The rear subframe is bolted to the body with rubber bushings that deflect under load. Prothane makes polyurethane subframe bushing inserts that tighten up the rear end for better traction and feel.

Installation Tips and Considerations

Alignment After Suspension Work

Any change to ride height or replacement of control arms will affect alignment. Always get a professional alignment after installing suspension parts. For lowered cars, you may need adjustable control arms or camber bolts to bring the alignment within spec.

Tools You Need

Strut removal requires spring compressors, a breaker bar, and penetrant oil on bolts. Many suspension bolts are torque-to-yield and should be replaced with new ones. Consider renting a spring compressor or having a shop assemble the struts to avoid injury.

Year-Specific Differences

195-1996 cars have different strut mounts than 1997-1999. Also, turbo models have thicker sway bars and different spring rates. Always verify part numbers for your specific model year and trim.

Recommended Brands for 2G DSM Suspension Parts

For reliable replacements, KYB and Monroe offer good quality at reasonable prices. For performance, Koni, BC Racing, and Eibach are trusted names. For bushings, Energy Suspension and Prothane are the go-to. Avoid generic parts from discount stores; they often don't fit correctly or wear out quickly.

Final Recommendation

For most 2G DSM owners, starting with a refresh of worn struts and bushings is the best first step. Replace the front and rear struts with KYB GR-2 or Koni Yellows, install polyurethane bushings on the sway bars and trailing arms, and add a set of Eibach Pro-Kit springs. This combination will ride well on the street, handle corners confidently, and last many miles. If you're building a dedicated track car, invest in coilovers and adjustable camber/caster plates. Always prioritize safety and alignment after any suspension work.
