Unlike more conventional wound springs, barrel shaped springs provide multiple spring rates to the difference of spring diameter.\u003c\/p\u003e\n\u003cp\u003eBy taking advantage of the characteristics of this shape, its possible to achieve a suspension setup that uses a lower spring rate around the 1G load range - where ride comfort is most important - and a higher spring rate during high-speed cornering.\u003c\/p\u003e\n\u003cp\u003eThese spring rates were tested across various conditions, including winding roads and mini circuits, and were set at 4.5 kgf\/mm for the front and 5.1 kgf\/mm for the rear.\u003c\/p\u003e\n\u003cp\u003ePaired with these carefully calibrated spring rates, a 20mm ride-height reduction balances increased stiffness with supple low-speed behaviour. The result is sharper turn-in and improved body control without compromising ride quality on imperfect surfaces. Equally at home on daily commutes or circuit work.\u003c\/p\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eRide height change:\u003c\/strong\u003e -20mm front and rear\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpring rates: \u003c\/strong\u003e4.5kgf\/mm front, 5.1kgf\/mm rear\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"torquegt","offers":[{"title":"Default Title","offer_id":58024088371525,"sku":null,"price":422.1,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0895\/2014\/4709\/files\/51400-BF1-001.png?v=1779355119","url":"https:\/\/torque-gt.co.uk\/es\/products\/spoon-sports-progressive-lowering-springs-prelude-bf1","provider":"Torque GT","version":"1.0","type":"link"}
