Eibach's Pro-Kit is a four-spring set of progressive coil springs for the 2016–2021 Honda Civic, meant to replace the factory springs at all four corners. The manufacturer positions it as a way to add sharper handling and a lower, more aggressive stance while keeping everyday ride quality. It was tested with factory dampers, so many buyers can lower the car without replacing the shocks at the same time.
Compared with stock springs, the kit is built to lower the center of gravity, which helps the car stay flatter and more controlled through corners. Buyers weighing it against cheaper springs should note the manufacturer's stated factory-damper testing and its five-year warranty, which backs the purchase beyond a short return window. Fitment is trim-specific, so check your model against the manufacturer's application list. Owners on user forums describe a manageable rear swap and a more involved front swap that calls for a spring compressor, which makes this a solid weekend project for a DIYer with the right tools.
The manufacturer lists the Rear Camber Kit part 5.67476K as required for proper alignment after installation.
The manufacturer's application list covers the 2016–2021 Civic Base Sedan, Base Hatchback, and Base Coupe, plus the 2017–2021 Sport Hatchback. Confirm your trim with the manufacturer before ordering.
The manufacturer notes that the kit was tested with factory dampers. Owners on user forums commonly keep the stock shocks after lowering, but the condition of worn shocks should be checked before installation.
Owners on user forums say the rear is the simpler end of the job: lower the control arm with a jack under it and swap the springs without removing the shock. The front takes more work and needs a spring compressor. Remove the axle nut and push the hub inward so the axle does not pop out, and take care not to cut the axle boot. Do not trim the bump stops, since owners warn that the extra compression can lead to shock failure. Some owners also remove the dowel pin on the front top hat, which they report adds roughly half a degree of negative camber. Always finish with a proper alignment and the rear camber kit.
