It's the spring you buy when you want the Si to look right and handle better without turning it into something you have to think about on a bad road. Around an inch down, progressive rate, and engineered to work with the shocks already on your car. For a lot of Si owners, this is the correct amount of lowering rather than a compromise.\u003c\/p\u003e\n\n\u003ch4\u003ePro-Kit Or Sportline?\u003c\/h4\u003e\n\n\u003cp\u003eEibach makes two options for this car and the difference matters.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003ePro-Kit\u003c\/strong\u003e drops around 0.9 to 1.1 inches. Enough to close the fender gap and lower the center of gravity meaningfully, while staying comfortable enough that you'd happily commute in it. This is the moderate, live-with-it option.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003e\u003ca href=\"https:\/\/www.hybrid-racing.com\/products\/eibach-sportline-lowering-springs-17-20-civic-si\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSportline\u003c\/a\u003e\u003c\/strong\u003e goes considerably lower, 1.5 to 1.8 inches depending on body style. More visual impact and a lower center of gravity, with more compromise on ride and less suspension travel to play with.\u003c\/p\u003e\n\n\u003cp\u003eHonest guidance: if the Si is your daily and you want it improved rather than transformed, the Pro-Kit is the right call and you won't regret it. If you want the car properly slammed and you're willing to accept a firmer ride, look at the Sportline.\u003c\/p\u003e\n\n\u003ch4\u003eYour Drop Depends On Body Style\u003c\/h4\u003e\n\n\u003cp\u003eSame spring for both cars, but they settle slightly differently.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCoupe:\u003c\/strong\u003e 0.9\" front and rear\u003cbr\u003e\n\u003cstrong\u003eSedan:\u003c\/strong\u003e 0.9\" front, 1.1\" rear\u003c\/p\u003e\n\n\u003cp\u003eThe sedan drops a touch more at the rear, which is a function of its factory ride height and weight distribution. Either way you're closing the fender gap and getting rid of the excessive ground clearance Honda builds in.\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Actually Feel\u003c\/h4\u003e\n\n\u003cp\u003eLowering the center of gravity does real work beyond how the car looks.\u003c\/p\u003e\n\n\u003cp\u003eLess weight transfer means less body roll in corners, less squat under acceleration, and less nose dive under braking. What you notice day to day is sharper steering response and a car that feels more settled and more willing to change direction. It's not a dramatic transformation, it's the car doing everything slightly more precisely than it did before.\u003c\/p\u003e\n\n\u003cp\u003eAnd the appearance change is genuine. The 10th gen Si leaves the factory with a lot of fender gap, and closing that up is the single biggest thing you can do to how the car looks for the money.\u003c\/p\u003e\n\n\u003ch4\u003eProgressive Rate Is Why It Rides Well\u003c\/h4\u003e\n\n\u003cp\u003eThis is the engineering behind the Pro-Kit's reputation.\u003c\/p\u003e\n\n\u003cp\u003eA linear spring has one rate throughout its travel, which means a spring stiff enough to control body roll is also stiff enough to punish you over every expansion joint. It can't tell the difference between a corner and a pothole.\u003c\/p\u003e\n\n\u003cp\u003eEibach winds these progressively, so the rate climbs as the spring compresses. Road texture and small imperfections only work the softer portion of the spring, while a corner or a real compression brings up the stiffer rate. That's how you get better handling without giving up ride quality, and it's why the Pro-Kit is the spring people keep on daily-driven cars.\u003c\/p\u003e\n\n\u003ch4\u003eWorks With Your Stock Dampers\u003c\/h4\u003e\n\n\u003cp\u003eEibach designs and tests these for the factory shocks, so you don't need to replace dampers to run them.\u003c\/p\u003e\n\n\u003cp\u003eOne honest caveat. That assumes your dampers are in good condition. If your Si has real miles on it and the shocks are worn, lowering the car will make that obvious immediately, and you'll blame the springs when the dampers are the actual problem. Worth being realistic about their state before you order.\u003c\/p\u003e\n\n\u003ch4\u003eBook An Alignment\u003c\/h4\u003e\n\n\u003cp\u003eDo this. Lowering the car changes camber and toe, and skipping the alignment means eating tires and driving something that won't track straight. Budget for it as part of the job rather than an afterthought.\u003c\/p\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cp\u003e2017-2020 Honda Civic Si, coupe and sedan\u003c\/p\u003e\n\n\u003cp\u003ePart number E10-40-036-02-22.\u003c\/p\u003e\n\n\u003ch4\u003eWho Should Run These Springs\u003c\/h4\u003e\n\n\u003cp\u003eThis is for the Si owner who wants the car lower and sharper without giving up the ability to drive it every day. It's the safest lowering decision you can make on this chassis, it works with what's already under the car, and it fixes the one thing everyone notices about a stock Si, which is how much air is sitting in the fenders. Check your dampers, book the alignment, and get it sitting right.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e 2017-2020 Honda Civic Si, coupe and sedan. \u003cstrong\u003ePart number:\u003c\/strong\u003e E10-40-036-02-22. \u003cstrong\u003eDrop, coupe:\u003c\/strong\u003e 0.9\" front and rear. \u003cstrong\u003eDrop, sedan:\u003c\/strong\u003e 0.9\" front, 1.1\" rear. \u003cstrong\u003eDesign:\u003c\/strong\u003e progressive rate, engineered for factory dampers. \u003cstrong\u003eWarranty:\u003c\/strong\u003e Eibach Million Mile.\u003c\/p\u003e\n\u003c\/li\u003e\n\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Drop\u003c\/strong\u003e\u003cbr\u003eCoupe: 0.9\" Front, 0.9\" Rear\u003cbr\u003eSedan: 0.9\" Front, 1.1\" Rear\u003c\/p\u003e\n\u003c\/li\u003e\n\n\n\n \n\u003cli id=\"Included\"\u003e\n\u003cp\u003e(2) Front Lowering Springs\u003cbr\u003e(2) Rear Lowering Springs\u003c\/p\u003e\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\n\u003c\/ul\u003e\n","brand":"Eibach","offers":[{"title":"Default Title","offer_id":46614229549090,"sku":"EBH-E10-40-036-02-22","price":395.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/884aca5cf71d78dc42894d9af26b507aL.jpg?v=1787861092","url":"https:\/\/www.hybrid-racing.com\/products\/eibach-pro-kit-lowering-springs-17-20-civic-si","provider":"Hybrid Racing","version":"1.0","type":"link"}
