Transform the handling and stance of your classic Mercedes-Benz R107 SL or SLC with this Height Adjustable SportLine Suspension Spring Kit – developed in-house by SLSHOP to solve the long-standing shortcomings of factory springs.
Unsatisfied with the “one-size-fits-all” approach of most aftermarket kits, we set out to engineer a better solution – one tailored to the realities of the W107 platform.
Whether you’re chasing tighter handling or simply want to refine the stance of your SL/SLC, this kit gives you complete control – our system is engineered with precision adjustability at its core.
The Problem We Solved
No two 107s are the same. Across nearly two decades of production, Mercedes built variants with wildly different specifications. Depending on engine, transmission, heater, seating, cabin extras… the total vehicle weight can vary by over 215kg. That means a spring setup that works perfectly on one car can leave another sitting nose-high and unbalanced.
This is where our kit makes the difference. By combining high-performance springs with fully adjustable perches, you can fine-tune your ride height to suit your specific car and preferences – whether you’re after subtle improvement or a more aggressive drop.
Why Choose This Kit?
• Height adjustable design – fine-tune your ride from standard height down to approximately 40mm lower*
• Engineered for all R107 roadster and coupe variants – from a lightweight 280 to heavier, option-loaded 560.
• In-house development – created by 107 specialists to solve widely-known handling issues.
• Ride your way – achieve the look and feel you want, without compromise
What’s Included
• 4x Height Adjustable Springs – developed in partnership with Eibach, world leaders in performance spring technology
• 44x Height Adjustable Spring Perches – designed in-house by SLSHOP. Made form 6061 Aluminium and hard-anodise coated for longevity.
• 2x Adjustment Spanners – to set and fine-tune your ride height with confidence
Installation Notes
This kit is a direct-fit replacement for your existing springs and uses the original Mercedes-Benz rubber shims – no irreversible modifications required.
For those wanting more, different thickness shims can extend your adjustment range but you should consider damper length and wheel arch clearance if you’re pursuing an aggressive drop.
Recommended Upgrades
To get the most from this suspension setup, especially during spirited driving, we recommend pairing it with our SportLine Anti-Roll Bar Kit and KONI Adjustable Dampers. It’s also the ideal time to replace your original rubber shims – a simple step of preventative maintenance to ensure you get the most out of the suspension for longer.
Fitting Applications
This kit is compatible with all Mercedes-Benz SL (R107) and SLC models produced between 1971 and 1989, including:
• 280 SL / 280 SLC
• 300 SL
• 350 SL / 350 SLC
• 380 SL / 380 SLC
• 420 SL
• 450 SL / 450 SLC
• 500 SL / 500 SLC
• 560 SL
The Verdict
If you’ve driven a stock R107, you’ll recognise the familiar body pitch under acceleration, nose-dive under braking, and vague feel through corners. This kit brings your SL or SLC into the modern age of handling – without sacrificing the comfort and character that make these cars so rewarding to drive.
It’s not just an upgrade. It’s the suspension your R107 should have had from the factory.
*Height range is based on average vehicle weights and suspension loads – actual results may vary. Always check clearance and suspension travel after installation.
