Tein 12-13 Honda Civic Si (FB6/FG4) Street Basis Z Coilovers

Tein is well-known for making performance suspension parts that offer a noticeable improvement in handling. The Street Basis Z coilovers for your 2012-2015 Honda Civic Si (and 2013-2015 Acura ILX) are built to give you that sportier feel and adjustable ride height you're looking for, without breaking the bank. These are a solid option if you want to lower your car and get a more responsive feel on the road.

These coilovers use a twin-tube damper design, which is a popular choice for street performance because it offers a good balance of comfort and control. They come with Tein's own PVS (Progressive Valve System) to help manage damping force across a range of speeds, giving you a smoother ride over bumps than you might expect from a performance coilover. The spring rates are carefully selected to work well with the vehicle's original sway bars, so you get improved handling without needing to upgrade every single suspension component. You can adjust the ride height using the included spring seats, allowing you to dial in the perfect look and stance for your Civic Si. The upper mounts are often integrated, making installation a bit more straightforward as you don't have to worry about reusing your old ones.

When installing these coilovers, you'll be able to set your desired ride height. It's a good idea to have an alignment done after installation to ensure everything is tracking straight and true. While these are designed for street use and offer a comfortable ride for a performance coilover, remember that lowering a vehicle can sometimes affect the factory suspension geometry. Tein's reputation for durability means these should hold up well for daily driving and spirited canyon runs alike.
