XYZ Racing Street Advanced Coilovers — Honda CIVIC SI FB6/FG4 TYPE 2 2012-2015

The ninth-generation Civic Si left the factory soft. Honda gave the FB6 sedan and FG4 coupe a willing 2.4-litre K24 and a helical limited-slip differential, then tuned the dampers for comfort first – so the nose washes wide under load and the body leans long before the front tyres have given up. The XYZ Racing Street Advanced coilover for the Honda Civic Si is built to address exactly that, without turning a usable daily into a track-only car.

Street Advanced sits where most Si owners actually drive: a car that commutes through the week and gets leaned on hard on a good B-road or the odd track day. With 720 damping adjustment settings plus independent height adjustment on each corner, you can run it supple for the motorway and firm it up when the road opens out.

What these coilovers do for your 2012-2015 Honda Civic Si

Drop the ride height and you pull the FB6/FG4’s centre of gravity down, which is the single biggest lever against the factory body roll. Turn-in gets crisper, the front axle settles faster mid-corner, and the helical diff starts pulling you out of bends earlier instead of scrabbling. The 720-way damping range is the part you will feel day to day – soften it off for broken urban tarmac, then wind in compression and rebound before a session so the chassis stops floating over kerbs and crests. Corner-by-corner height adjustment also lets you set a level stance and balance the car across the axles, useful on a front-drive Civic that carries its weight over the nose.

About the Street Advanced coilover

Street Advanced is the most popular kit in the XYZ Racing range, and the one built to do the most jobs. It has been developed over several years by XYZ’s own engineering team and refined through testing in races worldwide, which is where the damping calibration comes from. It is aimed squarely at normal road use and track days rather than one narrow discipline, with 720 individual damping settings so the same hardware suits a relaxed cruise or a committed lap. The brief is simple: give a driver chasing more pace genuine control over how the car rides and handles, on one set of coilovers.
