In a earlier SCD article we detailed the in depth improvement and testing programme of our Suspension Secrets and techniques Porsche Circuit Dealing with Pack. After being signed off, our kits have since been in service on quite a few 911 GT3s, GT3 RSs and Cayman GT4s throughout the UK and the remainder of the world.

Inspired by this success, we once more enlisted the assistance of RMA Observe Days MD, Leyton Clarke in an try to push the equipment to its absolute limits and to see what it may actually obtain. Beforehand, Leyton’s exceptional velocity and consistency as a driver, alongside his technical suggestions, was invaluable within the improvement of our Porsche Circuit Dealing with Pack, however this time our goal was pure velocity.
With Leyton on the helm of his Suspension Secrets and techniques Porsche Circuit Dealing with Pack geared up Porsche 911 GT3 RS Weissach, we visited a few of the UK’s hardest circuits and set the automobile towards the stopwatch. Over the course of the final six months, Leyton claimed what have been on the time three outright street automobile lap data at Donington Park GP, Manufacturers Hatch Indy, and Oulton Park Worldwide.
Throughout a go to to Fort Combe, Leyton obtained a reasonably sudden endorsement of the Porsche Circuit Dealing with Pack’s capabilities. In the midst of a session he was black-flagged, and after enquiring with the marshals as to the character of the black-flagging, he was instructed he was, “merely going too quick”.
Having tackled a few of the UK’s finest circuits with success, we seemed for the subsequent challenger to beat and the reply was apparent — the Nürburgring Nordschleife. Dubbed ‘The Inexperienced Hell’ by Jackie Stewart, the Nürburgring is broadly thought-about to be probably the most technically difficult race observe on the planet, and is the last word check for each automobiles and drivers.
After some last-minute arrangemenets, the date was set and we made the journey to the Eifel Mountains to sort out the fabled 12.9 miles of undulating and terribly bumpy tarmac that makes up the Nordschleife.
Just lately, the Nürburgring has turn into a battleground, with automobile producers one- upping one another in an try to say the general street automobile lap file. While the aim of our journey was to not attempt to set a scorching lap time, we couldn’t assist however strap some timing gear to Leyton’s GT3 RS for our personal curiosity.
When in Rome…
The truth is, the principle goal of our go to to the Nürburgring was to collect information on our Circuit Dealing with Pack and the way it carried out on the last word check observe.
One of many key upgrades of our Porsche Circuit Dealing with Pack is to put in a shorter and stiffer entrance spring. This offers the chassis some all-important rake angle which improves turn-in, reduces nose- diving on the brakes and makes path braking way more intuitive. This decrease entrance spring is mixed with a re-engineered damper cup that enables the entrance dampers to retain their commonplace vary of operation together with the decrease entrance spring.
Leyton’s automobile runs a decrease entrance spring than ordinary which drops the entrance axle fairly significantly, and to some extent the place some have commented that maybe it’s too low for the Nürburgring. Among the older arms on the Nürburgring even declared operating such a low entrance trip top as ‘unattainable’. The consensus for the Nürburgring is to run a barely increased nostril as a way to stop any entrance splitters from being broken over the bumpier sections.
As a way to check our equipment to the fullest, we selected to maintain the setup that was utilized to Leyton’s Porsche when he set the UK lap data. This meant operating a really quick entrance spring and having religion in our redesigned spring cup.
After we found that the entrance splitter, that was sat mere inches from the bottom, had barely even brushed the tarmac over the course of a whole day, that was an incredible vindication of our design and our willpower to realize what was thought-about an impossibility.
We then started our testing routine and have been thrilled when Leyton reported again to us that
the soundness of the automobile, even over the hardest bumps and jumps, was infallible. This extra stability, mixed with the flexibility — because of the Circuit Dealing with Pack — to hold way more velocity into the corners, allowed Leyton to shortly settle into a quick and constant tempo, regardless of typically heavy site visitors.
Our Circuit Dealing with Pack is designed to be supple sufficient for the street while additionally drastically bettering observe efficiency. In setup phrases, the Nürburgring is taken into account to be extra of a ‘quick street’ than a pure observe setup because of the elevation modifications, various tarmac high quality and uneven surfacing. Our alternative to keep up this suppleness in comparison with a conventional very stiff setup that emphasises wrought iron physique management, allowed Leyton to sort out even probably the most treacherous sections of the Nordschleife with out experiencing any undesirable suspension deflections.
After two days of intensive testing we have been happy that we had pushed our Suspension Secrets and techniques Porsche Circuit Dealing with Pack to the restrict on the hardest observe of all of them.
Leyton managed to file a Bridge to Gantry time of 6:52 on a vacationer lap, with site visitors and in 30+ levels climate, which was very encouraging and stands as a testomony to our Suspension Secrets and techniques Porsche Circuit Dealing with Pack.
We all the time attempt to push what is feasible with these automobiles and after two exhausting days on the Nürburgring we thought there was no higher manner of celebrating than heading to Europe’s second most well-known race observe, Circuit de Spa- Francorchamps, the place Leyton once more put the equipment to the restrict. Once more, our equipment’s enhancements to the caster and camber settings of the GT3 RS allowed Leyton to essentially lean on the chassis in the course of the increased velocity corners, such because the quick left hander at Blanchimont.
The top of our go to to Spa was the scarcely plausible tempo at which Leyton was in a position to assault the Eau Rouge/Radillion complicated on the prime of fifth gear solely to elevate for a slight second, downshift, after which bury the throttle on the way in which up the hill.
Fairly spectacular for only a street automobile!
