This application is built specifically for the E82 1M Coupe — BMW's short-lived, purpose-built performance coupe powered by a tuned version of the N54 twin-turbo inline-six — giving it the same balance of handling sharpness and street-usable ride comfort H\u0026amp;R aims for across its Street Performance line.\u003c\/p\u003e\n\u003cp\u003eEvery damper uses a fully threaded shock body, so ride height is set continuously rather than in fixed steps and can be fine-tuned corner by corner. The dampers are mono-tube gas units built from premium materials for a lower center of gravity and improved control, with H\u0026amp;R quoting an average height-adjustable range of 1.0 to 2.5 inches across the Street Performance line.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDamper: custom-valved mono-tube gas shock, matched to a progressive-rate H\u0026amp;R spring\u003c\/li\u003e\n\u003cli\u003eRide height: fully threaded shock body, continuously adjustable\u003c\/li\u003e\n\u003cli\u003eHeight-adjustable range across the Street Performance line: approx. 1.0\" – 2.5\" on average\u003c\/li\u003e\n\u003cli\u003eSprings manufactured in-house by H\u0026amp;R from 54SiCr6 alloy spring steel and shot-peened\u003c\/li\u003e\n\u003cli\u003eWarranty: 2 years on H\u0026amp;R Street Performance Coil Overs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eComplete H\u0026amp;R Street Performance Coil Over kit as supplied by H\u0026amp;R Special Springs.\u003c\/li\u003e\n\u003cli\u003eSee the fitting instructions supplied in the box for the full bill of materials.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-wheel alignment\u003c\/strong\u003e — H\u0026amp;R requires the wheel alignment to be checked and reset any time vehicle ride height is changed.
