{"type":"firestarter.listing","listing":{"id":"lst_KZxEq2Ux","product_name":"H&R Premium Coilovers | VW Mk4 | 2.0L","category":"Suspension > Coilovers","description":"Engineered for street and occasional track use, H&amp;R Premium Coil-Overs feature a fully-threaded aluminum front strut body rather than the heavier steel front strut bodies used in other kits, resulting in a 30-40% weight reduction when compared to stock struts. As with the standard H&amp;R Sport coilover kit, the adjustability will allow you to precisely dial in height adjustment to achieve optimum weight transfer, or simply get the aggressive look you've been looking for. Featuring H&amp;R's exclusive dynamic damper technology, each shock is engineered to work in harmony with a progressive-rate spring, together creating a finely-tuned suspension system.\nIf lowering your vehicle more than 1.4” and it has 42mm or larger drive shafts you must use H&amp;R front sway bars.\nLowering: F1.8 - 2.8\" / R1.8 - 2.5\" (Wheel Offset is critical in fitment)\nPhoto used for reference only. Actual product may vary.\n \nH&amp;R was founded by Werner Heine and Heinz Remmen in the 1970's with a simple idea in mind; with improved suspension, vehicles would have more control and better handling.","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/HR_COILOVER_STOCK_IMAGE_8de76eb5-6b68-4c73-b7c9-4ecc07c12db0.png?v=1782351960"],"price":1258.11,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-07-03T16:46:21.630Z"},"share_url":"https://firestarter.network/l/lst_KZxEq2Ux","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
