The 8th-gen Civic Si (FB6 sedan / FG4 coupe, 2012-2015) has a well-documented aftermarket, but coilover fitment on this chassis is split by year — a kit built for the 2012-2013 Si often isn’t the same part number as one for 2014-2015. Every kit below has confirmed FB6/FG4 fitment; check the exact year range against your car before ordering, since that’s the single most common mistake buyers make on this platform.

The picks, in detail
BC Racing BR Series
The most popular entry-level coilover for this chassis, covering the 2012-2015 Civic broadly — note the BR kit specifically excludes the 2014+ Si, so check the DS kit below for that year.
- 30 levels of adjustable damping
- Mono-tube shock design
- Separately adjustable ride height
- Full coilover kit, all four corners
- Best-known budget coilover brand in the Honda scene
- Wide range of damping adjustment for the price
- Doesn’t cover the 2014-2015 Civic Si specifically — verify your model year before buying
- Ride quality firmer than stock, as expected for a coilover
BC Racing DS Series
BC’s step-up digressive-piston coilover, sold specifically for the 2012-2013 Civic Si (FB6/FG4) — the pick if the BR kit’s year exclusion above rules it out.

TruHart StreetPlus
A twin-tube street coilover sold in two distinct kits — one for 2012-2015 Civic / 2012-2013 Si, another specifically for 2014-2015 Si — so match the kit to your model year.
- Twin-tube shock design
- Independently adjustable lower mount for ride height
- Front camber plates included
- 1.5″-4.0″ drop range

Megan Racing Street Series
A 32-way adjustable coilover sold in separate kits for 2012-2013 and 2014-2015 Civic Si, with front camber plates included on both.

Buying tips
- Confirm whether your Si is a 2012-2013 or 2014-2015 model before ordering — several brands here (BC Racing, TruHart, Megan Racing) sell different part numbers for those two ranges, and the BC Racing BR kit excludes the 2014+ Si entirely.
- A mono-tube design (BC Racing, Yellow Speed) generally rides firmer and responds faster than a twin-tube (TruHart) — pick based on whether the car is a daily driver or sees regular track/autocross time.
- Budget on a professional alignment after installing any coilover kit; ride height changes alter camber and toe enough to cause uneven tire wear if left unchecked.
