086-090 PVW 0512 28/03/2012 14:14 Page 86 ow unless this is your very first time picking up a copy of the mag, we’re pretty sure you don’t need us to tell you who KW Automotive is or what it’s all about. And if it’s not your first time but you do need us to fill you in, we’ve got to ask, where have you been all this time?! After all, KW Automotive is one of ‘the’ names when it comes to premium suspension in the VAG scene, look under the arches of any serious car parked up in any showfield or track day car park and there is a high chance you will see KW’s trademark purple and yellow colours looking back at you. But while we all N might know the KW Automotive name, we bet there aren’t many out there who know where it comes from and more importantly, where it’s going and what it has in store. So with that in mind, we decided to take a trip down to the German company’s new purpose-built UK HQ near Rochester to meet up with KW UK main man Richard Goode and get a closer look at the brand. And what a place it was, but more on that later… For starters, it might be somewhat surprising to learn that KW didn’t exist at all until it was formed in 1992 by Klaus Wohlfahrt. But it will be more surprising to learn that the coilover system we all know and love so much didn’t even exist until KW pioneered it back in 1995 – before then the idea of height adjustable suspension was strictly for the race track. If that wasn’t impressive enough then the rate at which KW has grown in both scale and technology is what really blows you away – from just three employees and 150sq metres of space when it formed in ’92 to 130 employees and 16,000sq metres of space at its base in Fichtenberg. But while it may have experienced rapid growth, KW still prides itself on specialising in ‘small scale’ runs, meaning that something can go from the drawing board to the production line in an 086-090 PVW 0512 28/03/2012 14:15 Page 87 Super Production Think coilover technology stopped with height adjustment and the ability to play with bump and rebound settings? Think again. We take a trip to KW Automotive UK to see the future of static suspension. Words: David Kennedy Photos: Si Gray incredibly short amount of time, perfect for the high-end brands it partners and the race teams it supports. KW even has its own ex-F1 seven-post rig at its factory, something that even some F1 teams don’t have. As the story goes, Klaus was at Autosport one year and got chatting to a member of what was the Honda F1 team at the bar. They mentioned that they had a seven-post rig they didn’t need anymore (like you do). Klaus said that he’d always wanted to own one and the rest, as they say, is history! The fact that KW had to build an entirely new facility to house the rig (it also took two lorries to deliver it over to Germany and once it was in place, took four Honda engineers almost a year to set it up) might give you an idea of the complexity of the piece of kit we’re dealing with, but it was worth it as it can replicate any track condition. Interestingly KW now rent it out to other race teams, regardless of what suspension brand they use. But what makes KW as a brand cooler in our eyes is that founder Klaus Wohlfahrt was a VW enthusiast before he started the brand and an avid hillclimber. In fact it was his experiences in hillclimbing that led him to start developing his own suspension kits for the road, put simply, he thought he could do better than what was on offer already. And hillclimbing is just one area of motorsport where KW excel, a list that includes the WTCC, the Mini Challenge, endurance rally events and over 70 teams at the legendary 24 Hour Nürburgring event – even some teams that are sponsored by rival suspension manufacturers – very cool! What else is cool is that KW supply the suspension components for a lot of premium car manufacturers or specialist manufacturerapproved tuning brands. While we were at KW UK Richard showed us the coilover destined for the new AMG Black Series, specially designed by KW for the Black. It’s not painted in KW’s purple and yellow colourway but 086-090 PVW 0512 28/03/2012 14:15 Page 88 instead in matte black, obviously. KW also works with ABT Sportline, Roush, Gumpert and legendary Ferrari-tuner, Novitec Rosso. The company has also developed the suspension for the £120k BMW M3 GTS and the new Mini Coupé among many more, all given their own unique colour scheme and branding, of course. It’s thanks to KW’s ability to handle and specialise in small-scale production runs that means it is the preferred suspension choice of many race teams and manufacture-approved aftermarket brands; something that the team are very proud of. There’s also KW’s work in developing stainless steel construction of its components such as dampers – known as Inox-line – and the use of a polyamide composite for the spring collars. Put simply, KW’s components can take whatever the elements throw at them without corroding; something their infamous salt-bath display at Essen one year proved controversially. KW hasn’t just grown within itself, it’s also grown to take in other companies as well, including Weitec, which it purchased about five years ago, along with ST Suspensions, Belltech and LSD Doors too. So what of KW UK then? Well, KW’s UK division was set up in 2005 by Richard Goode and recently moved in to new premises; a brand-new barn/farmhouse setup with space for the admin and sales departments, a warehouse for stock, training facilities and a workshop capable of overhauling and rebuilding kits and dynotesting dampers. But we hadn’t just visited KW’s new headquarters to get a tour round, oh no. We also heard that KW had some pretty special new kits in the works too and a couple of pretty exciting demo cars in the workshop that we ought to get behind the wheel of – we didn’t need asking twice! So without further ado, let’s take a look at some of the exciting new developments from KW… Full DDC kit looks complicated but is actually pretty simple to fit – if you can instal normal coilovers and have a basic understanding of wiring then it shouldn’t be too hard 88 Performance VW 086-090 PVW 0512 28/03/2012 14:15 Page 89 KW’S DDC Now if you’re lucky enough to own a new Scirocco, Mk6 Golf, Tiguan or Passat, the chances are you already know what Volkswagen’s Adaptive Chassis Control or Dynamic Chassis Control systems are. Essentially, the optional extra allows the driver to adjust the car’s suspension damper settings from a button on the centre console in to three modes: Comfort, Normal and Sport. But until now, if you wanted to fit aftermarket suspension to an ACC/DCCequipped car, you had no choice but to sacrifice your ACC/DCC capability by fitting a module (KW supplied) to disarm the switching mechanism. Not anymore! KW has developed its own DDC kit that allows you to not only fit a set of proper KW coilovers but also retain the functionality of your car’s ACC button on the dash thanks to a plug ’n’ play connection to hook up with your car’s control systems. Clever stuff. But that’s not all. KW realised that some people might want the functionality of the KW DCC system, along with the performance and appearance benefits of a proper set of coilovers, while not having the factory ACC system to plug in to. A problem? Not at all, all the engineers at KW had to do was develop its own version of VW’s ACC system, control module and all. And that they did, and let us tell you right now, it’s a seriously impressive bit of kit! The kit is the same as the regular DCC kit in terms of the coilovers themselves, but with the added Electronic Control Unit (ECU) hooked up and hidden away and a small, subtle control button integrated in to the dash somewhere controls it. Very clever stuff, we’re sure you’ll agree. But we weren’t at KW just to hear about these latest developments and listen to a slick presentation from Richard, we were here to get behind the wheel and test them out for ourselves… BEHIND THE WHEEL First up was KW’s own Audi A6 TDI fresh from the factory in Germany fitted with KW’s own DCC kit complete with the control ECU hidden away to do the job of changing the settings for us. The small circular button on the centre console changes through three colours depending on what you’ve got the system set to: red for Sport, blue for Normal and pink for Comfort. Compared to say, a standard Scirocco, the KW Sport setting was a lot firmer and, indeed, sportier than the standard Sport setting on a normal ACC-equipped car, while the Normal setting too was stiffer than it’s OEM counterpart. In fact, with the car set in Sport, we were impressed at just how much we could hustle it around, far more than we thought a big ol’ A6 was capable of; testament to just how good the KW DCC system is. When we switched to the Normal and then Comfort settings, the car changed completely, the ride switching to a much softer (although still firmer than the OEM system) and more normal-road friendly ride. Impressed? You bet we were. In fact we were so impressed with the system we couldn’t help but think that it might well be the future of coilovers for road cars. It’s one thing to listen to Richard bigging up the products but to get out on the road and feel the car switching from rock-solid and track-ready to smooth as a factory car with just a couple of presses of a button totally blew us away. In fact the Audi was so good we almost didn’t want to take it back, but seeing as we had Richard’s own Scirocco R to go out in too before the end of the day, we thought we ought to head back and switch keys. As Richard’s Scirocco had VW’s own ACC system from the factory, Richard simply replaced the suspension with KW DDC coilovers and hooked up the control unit to VW’s ACC module. And it’s as simple as that – all the benefits of a proper set of coilovers, with the stock ACC button just in front of the gear stick still doing it’s job as VW intended it to do. And while the differences between Sport, Normal and Comfort weren’t quite as pronounced as they were in the Audi, they were still certainly noticeable. And 086-090 PVW 0512 28/03/2012 14:18 Page 90 coupled with the remap, grippy rubber and OZ Superturismo wheels, well, it was a seriously impressive drive. With the ability to take the family out in the car and have it ride almost as soft as stock and then have it stiff and dialled enough to tackle a track day the next, the KW DCC system really does offer the best of both worlds, and all at the press of a button. Impressed? You betcha. THE DDC APP But that wasn’t the end of the trick kit Richard had to show us. And he had certainly saved the trickest bit of kit till the end. What we’re talking about is the DCC iPhone App. Yep, an iPhone App for your suspension! An optional extra for the complete KW DCC kit, it allows you to control and adjust your suspension from your iPhone, iPod or iPad through a W-LAN module. You simply download the App, pair it with the module hidden away in your car and then you can switch between Sport, Normal and Comfort from your i-device. Pretty cool. But it’s not nearly as cool as what Richard showed us next. In addition to the standard settings, you can adjust the damper rates from 0% (maximum comfort) to 100% (maximum Sport), and unlike the normal kit you even adjust the front and rear axles separately. What’s more, you can save up to five different settings. You can have a track day setting, a comfortable motorway setting and a normal driving setting or whatever you can think of and you can email your settings to a friend with the same kit to use (or use settings a friend sends you). KW could even send you its preferred setting for a specific track too. An equivalent App is currently being developed for Android phones too. THE HYDRAULIC LIFT SYSTEM (HLS) AND DROP KIT We’ve covered KW’s Hydraulic Lift System (HLS) in our News pages before but it’s definitely worth going over it again. Put simply, the HLS kit comprises a hydraulic cylinder unit between the spring perch and spring on the coilover body. When the button inside the car is pressed, the cylinder expands to give 45mm of lift in four-five seconds at speeds of up to 50mph; just the thing for clearing speed bumps or tricky angled approaches in to car parks and the like. But as the hydraulic cylinder doesn’t compress itself while driving, it doesn’t alter your car’s handling. It can either be fitted to both the front and back or to either separately, and it can be controlled either by a dashboard-mounted button or by an optional remote control. What’s more, it can even be fitted as either part of a complete coilover kit, or as an upgrade to an already existing kit. The Drop Kit works in much the same way, but in reverse. This means you can set your car’s height up on coilovers and then the Drop Kit lowers the car an additional 20mm at up to 15mph at the touch of a button, all the while performing exactly the same as a normal KW coilover kit. Whoever said the traditional coilover was dead certainly hasn’t told the guys over at KW. And to think, KW has gone from developing the first street coilover to coilover systems that can have their damper rates adjusted from an iPhone in just 17 years. We can’t wait to see what the next 17 years will bring… l PRICES AND CONTACTS The KW DCC kit (that hooks up with your factory ACC system) starts from: £1625 + VAT The KW DCC kit stand-alone kit starts at: £1965 + VAT The WiFi module: £225 + VAT The KW Hydraulic Lift Kit starts at: £2192.52 + VAT (single axle) The KW Drop Kit starts at: £2500 + VAT (single axle) For more details on the KW range from Variant 1 through to Variant 3 coilovers, its new Sport Comfort Range, the DCC kits, the HLS and Drop Kits, contact KW Automotive on www.kw-suspensions.co.uk or by calling 0870 990 7536.
