The H&R Super Sport Spring kit (part 50487-77) is a lowering spring set for the BMW E82 1 Series coupe, covering the 128i and 135i. The manufacturer rates it at 2.2 inches of front drop and 1.6 inches at the rear, which is 0.4 inch more at each end than its Sport spring on the same chassis. Owners on user forums regard it as the lowest-riding spring option short of coilovers. Choose it over a generic budget spring when you want a visibly lower stance and a lower center of gravity for better body control, without committing to a full coilover system.
Fitment needs some planning. Owners on user forums have reported front struts bottoming out after fitting H&R's lower-profile sport springs on this chassis, and the Super Sport drops further, so check strut and bump-stop clearance before ordering. Pairing the springs with dampers designed for lowered cars is a sensible step, and a wheel alignment after installation is worth budgeting for because the new ride height changes suspension geometry. Enthusiasts searching for E82 135i coupe lowering springs, 2008-2013 BMW 128i Super Sport drop, or H&R 50487-77 install details will find the most relevant owner experiences on forums.
The manufacturer's application table lists the Super Sport at 2.2 inches front and 1.6 inches rear, compared with 1.8 inches front and 1.2 inches rear for the Sport spring (part 29187) on the same E82 chassis.
The manufacturer's application listing I confirmed covers the E82 coupe. Lowering figures for the E88 convertible vary across sources, so confirm fitment and drop with the manufacturer before ordering.
