107 300 SL | 0-60 in 5.9 Sec | 255 BHP
Signal Red / Cream Alcantara
Although the R107 SL was superbly engineered, we always knew the platform was capable of more. Customers were looking to make the car drive, respond and brake in line with modern performance standards. With this in mind, we started the SportLine project.
Using the 300SL as a base, we lightened the crank and flywheel, ported and polished the cylinder head, installed a performance camshaft and replaced the ignition and fuelling with modern components. Our team was also able to shorten the throttle linkage, which transforms the way the three litre six cylinder responds through the gears. With a custom exhaust and manifold, the 300SL SportLine produces 255bhp, which is more than a factory standard 500SL.
The car now drives and handles unlike any other R107 SL. It’s lively, it’s agile, and it wants to be driven. For drivers looking for the enjoyment of a classic car without compromising on performance, the SportLine is the perfect solution. If you’re looking for the best handling, most responsive and most rewarding 107 SL you’ve ever experienced, then the SportLine is for you!

It all started with a question: can the iconic R107 Mercedes-Benz SL meet the expectations of modern performance car drivers? After restoring, repairing and maintaining many R107s, we found customers asking the same sort of questions. Can we firm up the ride a little? Can we improve the pedal response? Can we get more power without losing the character of the car? And so, with the keen driver in mind, the SportLine project was launched.
Our team has years of experience working with the R107 SL, so we knew its strengths and weaknesses, and how best to extract more power from the wonderful straight-six engine. With its incredible build quality, open top format and sheer elegance, the R107 now satisfies the hard core driving enthusiast too.
With a worldwide reputation for quality and attention to detail, SLSHOP’s SportLine was always going to executed to the highest standards. It handles and responds like no SL you’ve experienced before, and is equally at home on the road, track or classic car meet.
We knew the R107 SL had potential and with SportLine we’ve created something truly special.
Our 300SL SportLine has been featured in Octane and Mercedes Enthusiast Magazine, amongst others. It has been displayed at various classic car shows, and used for classic car events around the country. If you are interested in the SportLine project, and would like to discuss a SportLine restoration of your own SL, do get in touch.
It doesn’t have to stop there, our extensive range of upgrade parts will give you a taste of SportLine at home. From Engine and gearbox upgrades to sports suspension and even cosmetic touches, you don’t have to undergo the full SLSHOP conversion in order to make improvements to the look and feel of your Mercedes SL where you want to most.
We’ve picked out some of our favourites, however; you can view our full range of SportLine performance parts in the catalogue below.
Performance anti-roll bars
Reduce pitching and body roll with our up-rated sway bars, offering better stability without compromising comfort through a combination of superior materials, a thicker diameter and polyurethane bushes.
Adjustable tow and camber kits
One of the biggest benefits to a cars handling is having it set-up and balanced properly. Our adjustable trail arm bushes allow Tow and Camber to be altered, where the factory set-up lacks this adjustment.
Adjustable coil springs
These stiffer coils with their adjustable spring cups offer a more modern feel to the drive of your SL, with the added stability of lowering the ride height by 70mm, or more if you like.
Drilled & Vented brake discs
Whether your preference is the city or a mountain road, you want the assurance that your Mercedes SL stops as well as it goes. With these heavy duty brake rotors and the option for performance pads, we’ve got it covered!
7×15” Bundt Alloys
Our dished 15” ‘Mexican Hat’ wheels fill the arch nicely whilst retaining the classic look. Also unlocking a plethora of compatible tyres when there is a very limited market for the now dated 205/14 size
Stainless Steel performance exhausts
Nothing but the best; our stainless steel exhaust systems have been hand crafted in the UK since the days when these cars were new. With the option to turn up the volume if you wish!
Limited Slip Differential
With the Sportline delivering an increase in BHP of more than 35% and improvements in throttle response, that extra Oomph needs somewhere to go. An LSD upgrade is a must have, one of our most popular Sportline upgrades.
Re-profiled steering wheel
Take control our your Mercedes SL with the SportLine steering wheel. A thicker profile, thumb pads and hand stitching give this old helm a new lease of life. Leather, of course!
