Will work on cars with EDC. Average lowering of 1.6\"F 1.0\"R \n\n\tFor those that want the ultimate in handling and an over-the-top highly aggressive look, UroTuning recommends the H&amp;R Super Sport Springs. Super Sport Springs will lower your vehicle approximately 1 - 1.6 inches and should be matched with high-quality sport tuned shock absorbers. Super Sport Springs also have a firmer spring rate than the regular Sport Spring. \n\n  H&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/28802-1.jpg?v=1783983427"],"price":424.15,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-07-14T01:31:31.929Z"},"share_url":"https://firestarter.network/l/lst_8Ab4tgi7","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
