Sportline R
107 Mercedes 450 SportLine | 0-60 in 4.0 Sec | 294 BHP
Signal Red / Bucket Seats, Roll Cage
Before the paint had barely dried on our road going SportLine 300SL prototype, SportLine Racer plans were being hatched.
So we took all of the lessons learnt with the SportLine build and applied them to a USA spec 450SL. By adding a manual gearbox and removing the restrictive exhaust system, we were able to extract a raw track beast from this sedate grand tourer. Then, the improved suspension geometry from the 300SL SportLine was tweaked for the extra weight of a V8 engine and combined with racing components to give the desired ride and handling.
The end result is truly exhilarating, a tremendously exciting proposition. Our SportLine R is fited with racing seats, harnesses and a roll cage and is compliant with most forms of classic motor racing.

SportLine ZERO: For Everyone
Sportline Driven
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? How 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.
Sportline Parts
But it doesn’t have to stop there. Our large range of upgrade parts will give you a taste of Mercedes SportLine at home. Engine and gearbox upgrades to sports suspension and even cosmetic touches… Ultimately, you don’t have to undergo the full SLSHOP conversion. Now, you can make improvements to the look and feel of your Mercedes SL at home.
We’ve picked out some of our favourites. However, you can view our full range of Mercedes SportLine performance parts in the catalogue below.
Performance anti-roll bars
Reduce pitching and body roll with our up-rated sway bars. With these, you’ll get better stability but remain comfortable. This is thanks to a combination of superior materials, a thicker diameter, and polyurethane bushes.
Adjustable tow and camber kits
One of the biggest benefits to a car’s handling is having it setup and balanced properly. So, our adjustable trail arm bushes allow tow and camber to be altered. Take note that the factory set-up doesn’t include this.
Adjustable coil springs
Stiffer coils with adjustable spring cups offer a more modern feel to the drive of your SL. And it adds stability of lowering the ride height by 70mm or more.
Drilled & Vented brake discs
Whether you prefer city or mountain roads, you want the assurance that your Mercedes SL stops as well as it goes. We’ve got it covered! Try these heavy-duty brake rotors, with the option for performance pads.
7×15” Bundt Alloys
Our dished 15” ‘Mexican Hat’ wheels fill the arch nicely. Also, it retains the classic look. Also unlocking a plethora of compatible tyres, in a very limited market for the now-dated 205/14 size.
Stainless Steel performance exhausts
At SLSHOP, we offer nothing but the best. Our stainless steel exhaust systems have been hand-crafted in the UK, since the days when these cars were new. Also, with the option to turn up the volume if you wish!
Limited Slip Differential
The Mercedes SportLine delivers an increase in BHP of more than 35%. Also, it has improvements in throttle response. That extra oomph needs somewhere to go! So an LSD upgrade is a must-have. This is one of our most popular SportLine upgrades.
Re-profiled steering wheel
Finally, 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!

Wet, dirty roads, mud, dust and snow… Not exactly the natural habitat of a well preened R107 SL, but for international endurance racing, an SL makes the perfect contender.
Sportline 300
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.
Sportline 500
Long before our 300SL SportLine reached the pages of glossy magazines, when it was an unpainted shell and boxes of unfulfilled potential, we knew that a V8 SportLine had to be next – what we didn’t have at the time was the right customer.
