The H&R 51855 is a four-spring lowering set for the 2008–2012 Honda Accord coupe with the four-cylinder engine. It replaces the factory coil springs at all four corners, so the car sits lower without converting to coilovers. Owners on user forums report a drop of roughly 1.5 inches in front and 1.3 inches in the rear, which reduces the fender gap and lowers the center of gravity.
Compared with stock springs, this set gives a tighter stance and less body roll in corners for far less than a coilover kit. Owners on user forums generally advise buying a name-brand spring over a bargain option and avoiding cut factory springs. Expect a firmer, sometimes bouncy ride over broken pavement, so this suits street driving more than track use. Forum regulars also recommend upgrading the shocks at the same time, because factory dampers are often worn out quickly once a lower spring rate is fitted.
Buyers searching for 2008-2012 Accord coupe 2.4L lowering springs, an H&R 51855 sport spring set, or a 1.5 front and 1.3 rear drop should note that this number is meant for the four-cylinder car. Owners stress matching the spring to the engine, so a V6 coupe needs its own part.
Owners on user forums advise matching springs to the engine, with four-cylinder cars using four-cylinder springs and V6 cars using V6 springs. This listing is for the four-cylinder coupe.
User forums commonly report that factory shocks wear out soon after lowering springs are installed, and many owners recommend replacing the dampers at the same time.
Part-number references for the sedan version are inconsistent across sources. Owners on user forums say the suspension is similar between coupe and sedan, but confirm fitment with the manufacturer before ordering.
This is a job for a home mechanic with a coil spring compressor and a solid jack setup. Owners on user forums describe compressing the spring with hooks at the top and bottom, then removing the strut assembly to swap the spring. Plan on a wheel alignment afterward, since changing ride height shifts camber and toe. One owner reported strongly negative camber after alignment and needed a rear camber kit to correct it. If you lack a spring compressor or an alignment rack, having a shop do the install is the safer route.
