APR is pleased to present the Racingline range of parts developed by Volkswagen Racing UK and distributed exclusively through APR's global dealer network. To learn more about VWR, please visit Volkswagen Racing UK's website.
VWR Sport Springs are specifically engineered to replace your factory springs with slightly shorter and stiffer springs. They are designed to lower your vehicle's center of gravity and reduce body roll for better handling all while maintaining the ride quality and comfort as if intended by the OEM. VWR found the current VAG OEM dampers are a much more sophisticated design than previous generations resulting in a worthwhile improvement in handling with little change. VWR painstakingly developed these springs to work perfectly with your OEM dampers and require no other changes to your suspension to take advantage of their benefits.
The VWR Sport Springs were developed for several VAG platforms all matching correctly to their respective OEM dampers, making this a very cost-effective modification. With different engines and vehicle weights, VWR has developed a range of springs specific to your vehicle and powertrain. These springs are fully compatible with Volkswagen's Switchable ACC (Adjustable Chassis Control) dampers.
A typical VWR Sport Spring customer is one who demands performance over stock without breaking the bank. These springs are not intended for customers looking to dramatically lower or track their vehicle. For those customers, VWR's full line of coilovers are available to suit your individual needs.
Engineering
Many springs available for VAG vehicles were either designed to be coupled with aftermarket dampers or are simply available to lower and stiffen the vehicle without any testing to stand behind the chosen stiffness or ride height. Through extensive development and testing, the VWR Sport Springs were optimized for each vehicle platform. Tens of thousands of miles across multiple vehicles were necessary to determine the ideal specifications for each spring set and VWR is very proud of the end results. VWR can guarantee with confidence they believe these springs to be the best for your VAG vehicle on the market.
Reducing Ride Height and Increasing Spring Rate
Each vehicle will be lowered differently, depending on platform. Most vehicles see a 20-25mm reduction in front and rear ride height. These heights were chosen in order to preserve the wheel travel needed to keep the usability of the standard car, with an increase in spring rate of around 10-15% depending on the type of car. Lowering or stiffening further, as some springs do, in VWR's experience will cause the vehicle to bounce and lose damper control as the dampers are mismatched to the spring-rate and will also cause the springs to run out of wheel travel. You also risk reducing the life of your dampers significantly by choosing the wrong springs, which the VWR Sport Springs are guaranteed not to do.
Lowering Spring Style and Spring Rate
VWR Sport Springs are a linear rate spring with a barrel-type shape so the end forms come slightly in. The springs have specific front and rear spring rates as seen below in the technical data table. This allows VWR to preserve the ride quality in normal use, but stiffens the spring rates at the ends of its travel when cornering or braking hard. The springs come in power-coated gloss VWR blue with Volkswagen Racing Logos and work especially well when combined with APR Roll Control or VWR Sway Bars.

Notes:
VWR Recommends a suspension alignment after installing sport springs as a part of the installation process. While the ride-height reduction keeps the geometry within the Volkswagen recommended tolerances, if your car is not brand new, it may have moved out of tolerance with use, so it's a good practice for your installer to verify alignment after install.
