{"type":"firestarter.listing","listing":{"id":"lst_-abWt68z","product_name":"APR MK8 Golf R Roll Control Lowering Springs","category":"Springs","description":"APR Roll-Control Lowering Springs greatly improve the looks and handling of your Volkswagen MK8 Golf R without greatly sacrificing comfort or your wallet! Designed for use with DCC or Non-DCC dampers, our performance lowering springs are a direct plug-and-play upgrade that offer a lower center of gravity and increased spring rates to reduce body roll.\n\nMany lowering springs on the market today simply lower your vehicle and give a false sense of improvement by feeling overly stiff. We took a different approach with our design. We extensively track and street tested several iterations to deliver a system that not only makes your MK8 Golf R look great, but does so while delivering a comfortable experience that doesn't constantly crash and bottom out the dampers. Through a proper ride height configuration, we're able to greatly increase spring rates for improved handling, but do so without leaving the ride harsh, bouncy, and uncomfortable. Your MK8 Golf R will be planted with a minimal impact on comfort. It's a system you'll love the second you're behind the wheel!\n\nThese springs were designed in house and manufactured in the USA using a premium high tensile chrome silicon steel for excellent resilience against sagging and failure for years to come. Each spring comes powder coated in our signature red color, further protecting the spring from the elements. The front and rear springs are a dual rate spring that will operate as a single rate, linear spring, under normal loaded driving situations. All center of wheel to fender (CF) measurements were recorded on our in-house US Spec 2022 MK8 Golf R (DCC) test vehicles and may vary slightly from vehicle to vehicle. Lastly, while this system was designed specifically for the MK8 Golf R, it will fit other similar platform vehicles.\n\nSpecifications: \n\nUS 2022 MK8 Golf R (DCC) Front: 365 mm (OEM) vs 344 mm (APR) or a 21 mm reduction in CF Height 220 lbs/in (OEM) vs 319 lbs/in (APR) or a 45% increase in Spring Rate\n\nUS 2022 MK8 G","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/sus00017_001.jpg?v=1696431561","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/sus00017_002.jpg?v=1696431561","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/sus00017_003.jpg?v=1696431561","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/sus00017_004.jpg?v=1696431561","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/sus00017_005.jpg?v=1696431561","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/f9c1d222d7f7327507e263716efc82392a0c4398.jpg?v=1696431561"],"price":274.95,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:21.911Z"},"share_url":"https://firestarter.network/l/lst_-abWt68z","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
