Performance Rear Drop Link Set, +30% Increased Rubber Hardness. Porsche 911 1978-89 / 930 1978-89

Performance Rear Drop Link Set, +30% Increased Rubber Hardness.
Upgrade your rear suspension linkage with this performance drop link set specifically designed for the Porsche 911 / 930 (1978-1989). Both left & right links included. Featuring stiffer rubber bushes with a 30 % increase in hardness versus stock, this set provides a stronger, more direct connection between the rear stabiliser bar and suspension arms — delivering sharper handling, reduced body roll, and improved rear-end feel under load. Ideal for spirited road driving, track use or any build where precision handling matters.

Fits:

• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50
• Porsche 911 1978-1989 3.3L Turbo (930)

What This Product Does:

• The rear drop links connect the rear anti-roll bar (stabiliser bar) to the rear suspension arms/axle. When the car corners, the anti-roll bar helps keep the body flatter by transferring load between wheels; the linkage must be rigid and responsive for full effect.
• By increasing the rubber hardness in the bushes by 30 % over standard, the link is less prone to flex, deformation or movement under load. This means the stabiliser bar engages more effectively, quicker and with less lost motion.
• The upgrade therefore yields sharper rear-end response, less body roll, better handling stability, particularly under spirited driving or track use.

Symptoms & Signs You Might Need It:

• You experience clunking or knocking noises from the rear suspension when going over bumps or during cornering — typical of worn drop link joints or flexible bushes.
  
• The car displays excess rear body roll, or the rear end feels less controlled in transitions — possibly the stabiliser bar isn’t transmitting force effectively due to soft/link compliance.
  
• You’ve upgraded other components (e.g., stronger springs, larger tyres, lowered ride height) but the rear still doesn’t feel tight — the stock links may be the weak link.
• The existing links have rubber bushes that are cracked, collapsed, excessively soft or you detect play in the link.
• Visual inspection of the rear links shows degraded bushings, movement under load, or the mounts appear worn.

Why This Upgrade Matters:

• Handling precision: With the stiffer bushes, the drop links provide a firmer connection, meaning the stabiliser bar is engaged earlier and more completely — improving turn-in, chassis balance and cornering feel.
• Complements suspension upgrades: If the rest of the suspension has been improved (e.g., springs, dampers, sway bar) then a stronger link makes sure the stabiliser bar isn’t held back by weak link hardware.
• Longevity and durability: The upgrade is likely to resist wear, deformation and fatigue better than standard softer bushings, thus maintaining performance over time.
• Value and driving enjoyment: For performance-oriented or track-use cars, the handling benefit is real. Even for road use, more solid links reduce movement, improve feedback and instil driver confidence.
• Prevents secondary issues: Poor drop links can lead to uneven tyre wear, shifting geometry or looseness — upgrading helps avoid these costly or dangerous side-effects.
