Drop Link Sports With 85 Shore Rating, Front. Porsche 964 C2 / C4 ❭ 9643430
- Porsche 964 (911) C2 1989-93
- Porsche 964 (911) C4 1989-93
Upgrade the front anti-roll bar linkages of your Porsche 964 with this high-performance sports drop link set. Designed specifically for the front left and right sides of the 964 C2 / C4 (1990-94) with the M030 sport suspension, these links feature an 85 Shore rated bushing material for minimal compliance and maximum chassis feedback. The result is improved roll resistance, sharper turn-in, and a more connected steering feel. Ideal for restored, tuned or track-prepped 964s, these direct-fit replacements deliver both performance and durability.
Fits:
- Porsche 964 (911) C2 1989-93
- Porsche 964 (911) C4 1989-93

What This Product Does:
- The front drop link connects the front anti-roll (sway) bar to the suspension (often via control arm or strut), transmitting roll forces and enabling the bar to limit body roll during cornering.
- A key role is to ensure that the anti-roll bar engages properly without undue delay or unwanted movement; the drop link is the “lever” that transfers motion.
- With the “85 Shore” version, the bushings (or joint material) are firmer (i.e., higher durometer) than the standard version — meaning less flex or slack in the link under load, so the anti-roll bar responds more directly and the front end remains flatter in corners.
- In practical terms this yields sharper front-end handling, reduced body roll, and a more direct “connected” feel through the steering and chassis.
Symptoms & Signs You Might Need This:
- Clunking or knocking noises from the front suspension when going over bumps or through quick directional changes — suggesting the current drop link or its mount is worn.
- Excessive body roll or vague front-end behaviour in corners — the anti-roll bar may not be transmitting load effectively due to flex in the link.
- Uneven handling left vs right — if one drop link side is looser than the other, you might feel asymmetrical behaviour.
- Soft or “mushy” front-end feel, especially if you’ve upgraded other suspension components (lowered car, stiffer springs) and the links are still standard and allowing unwanted movement.
- On inspection: visible sleeve or bushing deterioration, play in the link joints, or rubber flexing significantly under load.
Why This Upgrade Matters:
- The step from standard hardness to 85 Shore gives you a firmer connection in the drop link, meaning the roll bar is engaged more quickly and consistently under load. This is especially beneficial on a car like the 964 with sport suspension or for drivers seeking sharper response.
- It helps preserve and maximise the benefit of other suspension upgrades (e.g., stiffer springs, upgraded shocks, larger tyres) — because the weak link is removed. If the drop link is still soft or worn, the rest of your upgrades may be compromised.
- Better roll-control means more predictable handling, less chassis lean in corners, and improved tyre contact patch maintenance — which improves grip, cornering speed and driver confidence.
- From a maintenance perspective: worn drop links often lead to bushing failure or increased stress on the anti-roll bar and associated mounts. Upgrading proactively can reduce downstream costs and improve longevity.
- For a vehicle with sport heritage (964 C2 / C4) the upgrade aligns with the model’s dynamic capabilities, bringing front-end behaviour closer to tuned-chassis expectation.
