Poly Suspension Parts for the 2002 Porsche 911 996: A Complete Guide

If you own a 2002 Porsche 911 996, you already know it’s a capable sports car. But after twenty-plus years, the stock rubber suspension bushings have likely hardened, cracked, or sagged. Replacing them with polyurethane (poly) suspension parts is one of the most cost-effective ways to sharpen turn-in, reduce wheel hop, and get more consistent alignment. This guide covers everything you need to know about poly suspension parts for the 2002 996, including which components matter most, how poly differs from rubber or delrin, and what to look for when buying.

Why Upgrade to Polyurethane Bushings?

Factory rubber bushings are designed for comfort and noise isolation. Over time, rubber degrades from heat, oil, and age. Polyurethane is a dense, durable polymer that resists compression set and maintains its shape. The result: less deflection under load, more precise suspension geometry, and quicker steering response. Poly also lasts significantly longer than rubber—often the lifetime of the car. For a 2002 996, which already has a stiff chassis, poly bushings transform it into a more predictable track-day tool without making it unbearably harsh on the street.

Key Benefits

• Reduced flex: Poly bushings minimize unwanted movement in control arms, sway bars, and trailing arms.
• Better feedback: You’ll feel the road surface more directly, improving driver confidence.
• Longer life: Poly won’t crack or rot like rubber. It’s resistant to oil and grease.
• Consistent alignment: With less bushing deflection, your alignment specs stay put under hard cornering.
• Cost-effective: A full poly bushing kit costs hundreds, not thousands, and installation is DIY-friendly for intermediate mechanics.

Which Poly Suspension Parts Should You Replace?

Not all bushings need to be poly. Focus on areas with the most compliance. For the 2002 911 996, the weak spots are the rear trailing arm bushings, the front control arm (wishbone) bushings, and the sway bar end links. Here’s a breakdown:

Rear Trailing Arm Bushings

These are the biggest culprit for rear-end slop. The stock rubber bushings allow the trailing arm to move independently under load, causing instability during hard acceleration or cornering. A poly replacement (often a two-piece design) locks the arm in place, improving traction and reducing wheel hop. Recommended durometer: 80A-90A for a street/track balance.

Front Control Arm (Wishbone) Bushings

On the 996, the front lower control arms have two bushings: a front bushing (lollipop) and a rear bushing. Poly versions eliminate the vague on-center feeling and delay in turn-in. You can replace them individually or get a full kit. For street use, 80A poly is ideal; for track-only, consider 95A.

Sway Bar End Links and Bushings

Poly sway bar bushings reduce body roll transitions. They’re cheap and easy to install. Combine with adjustable end links for corner-weighting or lowering. Factory end links use rubber—poly end links with spherical bearings offer zero slop.

Coilover Spring Perch Bushings

If you have coilovers, the upper and lower spring perch bushings can also be swapped for poly to prevent squeaks and improve lateral location. Check if your coilovers use standard 60mm or 2.25” springs; some require custom-sized spacers.

Material and Durometer Guide

Polyurethane comes in different hardness ratings (durometer). Softer poly (70A-80A) mimics rubber feel with slightly better deflection resistance. Medium (80A-90A) is the sweet spot for a street-driven 996 that sees track days. Hard (95A+) is race-only and transmits significant noise and vibration. For winter-driven cars, stick with 80A-85A to maintain compliance in cold weather.

Poly vs. Delrin or Spherical Bearings

Poly is the best compromise for street use. Delrin (a hard plastic) has zero compliance and can cause binding or noise. Spherical bearings (rod ends) are the ultimate but are harsh, expensive, and need frequent greasing. Poly is the middle ground: easy to install, durable, and quiet when properly greased.

Installation Considerations

Installing poly bushings requires pressing out the old rubber and pressing in the new ones. Some are split so you can install them without a press. Here are tips for a smooth job:

• Use plenty of poly-specific grease (usually included) to prevent squeaking. Apply to both the bushing ID and the shell.
• Clean the metal sleeves thoroughly—rust or debris will cause binding.
• Torque bushing bolts at ride height, not on a lift. Poly bushings have less compliance; if you tighten them at full droop, the bushing will be preloaded when the car is on the ground, causing poor ride and premature wear.
• Expect slightly more NVH. A 80A poly kit will increase cabin noise by about 10-15% (mostly low-frequency hum) compared to fresh rubber. This is normal.

Top Polyurethane Brands for the 2002 996

• Powerflex: Offers comprehensive kits for front and rear. Their PFR80 material (80A) is street-friendly. Known for precise fitment and greasing channels.
• Elephant Racing: Specializes in Porsche 996/997 suspension. Their “Racing” poly bushings are slightly harder (approx 90A) and come with lifetime warranty. They also sell delrin options if you want race levels.
• SuperPro: Australian brand with good quality and rust-proof sleeves. Their “Road” series is 70A-80A; “Race” is 95A. Available in full kits.
• FVD Brombacher: German tuner offering poly bushings as part of suspension packages. Good for OEM+ upgrades.
• Tarrett Engineering: Known for motorsport parts; they offer spherical bearing upgrades for control arms, but also have poly options for street use.

What to Avoid

• No-name eBay poly bushings. Many are made from cheap urethane that degrades in UV or gets rock-hard within a year. Stick with reputable motorsport suppliers.
• Full delrin for street cars. Unless you autocross every weekend, delrin will drive you crazy with noise and vibration.
• Poly engine mounts. On a 996, poly engine mounts can cause excessive drivetrain vibration in the cabin. Stick with rubber or a semi-solid mount there.

Final Recommendation

For a 2002 Porsche 911 996 that sees both street and occasional track use, replace the rear trailing arm bushings and front lower control arm bushings with Powerflex or Elephant Racing poly bushings in 80A-85A durometer. Add poly sway bar bushings for a full refresh. Expect to spend $200-$400 on bushings and about 6-8 hours of labor if you DIY. The result is a sharper, more predictable car that still remains comfortable enough for daily driving. If you plan to track the car heavily, consider a full poly kit with 90A bushings and upgrade to adjustable coilovers at the same time. Poly suspension parts are the single best handling upgrade you can make to an aging 996—they fix the rubber’s shortcomings without breaking the bank.
