From the lessons learnt from developing and refining the race-versions of the Golf and Scirocco over the past decade, we are proud to release the StreetSport Coilover suspension kit to suit the enthusiastic road and track driver.
Our StreetSport suspension range is European made by the same team that build all of our full-race suspension, using exactly the same quality and materials that we insist on for the race cars.
Hence this well-proven kit provides an adjustable ride-height suspension system that genuinely offers the sort of quality, detailing and refinement that few of the ‘aftermarket’ suspension products can offer.
All of our kits use our premium monotube construction, which few kits at this level offer. Our whole Coilover family – from StreetSport up to our full-race TrackSport have also been designed by our engineers from the outset to be upgradable. As you will read below, uprated Linear Springs can be fitted at any point on all models, and the Adjustable Top Mount will also fit any kit, from road to race. Many customers have really enjoyed being able to uprate their suspension kit over a few months or years.
A bit of background if you are new to uprated suspension systems. A “coilover” suspension system replaces the entire standard front damper and spring with a high quality, motorsport orientated unit with much more sophisticated valving inside the dampers. It consists of a shock absorber with a coil spring encircling it. The shock absorber and spring are supplied assembled as a unit, allowing us to perfectly match the damping to the specified spring rate. The rear uses an adjustable ride-height spring and seperate damper. The result is a beautifully taut, controlled ride that feels like the best thoroughbred German sportscars that are firm over bumps, but never crashy around town nor floaty or loose at high speed.
Another very significant advantage of a coilover set up is that it allows full adjustment of ride height, using a simple threaded spring perch on the threaded body of the damper. This allows the car to run at your chosen height, from standard clearance down to ground-scraping show cars, whilst keeping the same spring length wherever you set it.
THE STREETSPORT KIT
The StreetSport Coilover suspension system differs from the StreetSport PLUS Coilover suspension system in that it has non-adjustable damping rates. Through extensive testing of spring and damping rates, our engineers have established the ideal settings for enthusiastic road driving, whilst maintaining a really suprisingly good ride quality.
The StreetSport kit is aimed at fast road use, and has been developed thoroughly to ensure that the comfort is not sacrificied – in fact, it is the beautiful, taut ride quality that most customers are most impressed by when they try the StreetSport Kit. This is certainly not a track set-up suspension.
As a non-adjustable suspension kit, this is a ‘fit and forget’ suspension kit that doesn’t require constant adjustment – suiting the customer who wants to get on with enjoying their car’s performance in the knowledge that suspension is already at its optimum settings.
The kit replaces the entire standard front and rear dampers and springs with high quality, motorsport-derived units with much more sophisticated valving inside the dampers for significantly better levels of wheel control than any mass-produced damper offers.
The StreetSport suspension system transforms a standard on track, having stiffer springing and damping rates. However, if you are serious about getting the most out of your car on circuit, we would recommend that you consider the PLUS 12-point adjustable kit.
The StreetSport kit is European-made from strong, durable stainless steel powder-coated in satin black for durability, using a 22mm shaft and anodised aluminium spring seats.
As a premium product, all our Coilover family are all of a monotube damper design. The main advantages of monotube dampers are that the pistons are much larger than those of twin-tube dampers, which are more normally the design that cheaper dampers follow. The larger monotube piston creates more flow through the valves than the smaller twin-tube piston as it can displace more oil through the valve; this makes the mono-tube damper more sensitive to small suspension movement.
The deflected-disc valve system found in our Monotube systems are more precise and consistent than the system of check valve, springs, and orifices commonly used in cheaper twin-tube dampers. Our Monotube dampers use much higher gas pressure which helps them to run much cooler than a twin-tube damper. This means our dampers are able to provide consistent damping performance under the harshest condition (such as track use).
Precision, consistency, and performance advantage mean parts used in monotube dampers have to be produce with higher accuracy than twin-tube dampers, and hence tend to cost more – but the benefits are clear to any suspension expert. We’d really recommend that customers don’t choose a twin-tube suspension system for your car without trying a monotube alternative first.
Each kit is made to the very highest of standards, produced alongside our full motorsport-specification suspension kits. We truly believe that by applying the standards demanded from high-level motorsport to a street suspension, there is no other coilover kit at this price-point that offers anywhere near the quality of engineering that the Racingline kits offer.
We have specified our own springs to match perfectly to the damping rate and car weight. These are finished in powder-coated blue with the RacingLine logo etched in.
The springs are carefully selected for each vehicle chassis’ design and weight, and come as standard with progressive springs. A progressive rate spring is one in which the spring rate changes depending on the amount of load placed on the spring, therefore the actual spring rate is not a fixed number. This allows the spring to offer a comfortable daily driving experience on the street yet offer excellent control over the bumps and sudden elevation changes seen on streets around the world.
A full linear front & rear spring upgrade is available which can be added at any time. A linear rate spring has a fixed spring rate, meaning the amount of weight needed to compress it does not change with the load. They offer less of a compromise than the Progressive Springs, which give a softer spring rate in the middle of their travel, but firm up towards the ends of their travel (hard cornering or braking for example). The Linear Springs are just a stiffer spring, all of the time.
The main advantage of linear springs is the consistency in the way that the weight transfer from one side of the car to the other side, it should be very smooth and consistent, this makes the dynamics much easier to predict as the driver can anticipate weight transfer and body roll more accurately. Hence Linear Springs offer superior control on the track over progressive springs but do so at the cost of comfort on the street.
These springs are designed to directly swap onto your StreetSport or StreetSport Plus suspension and are an excellent upgrade for anyone who frequents the track. Some customers even swap to the linear springs for a track day even and then back to the progressive springs when on the street. This is a key advantage of the our RacingLine Coilover suspension kits – other suspension kits do not offer this sort of upgradability.
TOP MOUNTS/CAMBER PLATES
Another unique design feature of our Coilover kits is that both Suspension Systems (StreetSport and StreetSport PLUS) are fully compatible with either Solid Adjustable Top Mounts or the standard rubber mounts. Unlike many Top Mounts available on the market, our mounts are a direct swap that require no cutting and are completely reversible back to standard.
THE END RESULT?
A true transformation in the way that your car rides and handles. Think how a Porsche 911’s suspension behaves – taut, controlled but never crashy or harsh – and you’ll have a good idea of how your car will feel with the StreetSport kit fitted. This was the brief to our engineering team – to adapt our race-winning motorsport suspension into something that would combine dramatic performance improvements whilst still delivering genuine day-to-day useability (see the picture, above, of our team benchmarking the new suspension against a couple of the industry’s best resolved suspension set ups – a 911 with PDC switchable suspension and a KTM X-Bow R). It was a tough challenge to reach – but we are thrilled with the end result.
Versions of the StreetSport suspension kits (both adjustable and non-adjustable) are available for all cars on the Golf platform: 5 and 6, Scirocco, Jetta 07 and Jetta 11, Beetle 12, A3 and S3, TT, Leon, Octavia and others.
The StreetSport Coilover suspension kit is available for 2 and 4 wheel drive cars on the Golf/Scirocco platform. Our Anti Sway Bars are highly recommended with this kit too.
This kit is compatible with cars fitted with Volkswagen’s switchable ACC suspension – although it’s important to be clear that the dampers loose the switchability of the standard dampers, and an additional electronic box is required from us at extra cost in order not to generate fault codes in the car.
For information, we also offer the Competition Coilover suspension kit which is an altogether stiffer set up for circuit cars, with 3-way adjustable damping rates for both bump and rebound. It’s ideal for the more track-orientated car, but it’s a significantly stiffer spring and damper rate than the StreetSport Kit. Please feel free to ask us for advice on choosing between the two.
