XYZ Racing Street Advanced Coilovers — Kia K5- OPTIMA (TYPE 1) 2010-2015

The 2010-2015 Optima rides on soft factory springs and long-travel dampers that let a nose-heavy front end wallow through quick direction changes. The XYZ Racing Street Advanced coilover for the Kia K5- Optima (Type 1) tackles that directly, swapping the saloon’s compliant but vague setup for height-adjustable struts and 720 ways of damping control.

This is XYZ Racing’s enthusiast street kit, built for owners who use the car every day but want it to feel tied down on a B-road or the occasional track day. You set the ride height to close the large factory wheel gap, then tune the damping to suit how the K5 is actually driven.

What this coilover does for your 2010-2015 Kia K5- OPTIMA (TYPE 1)

Lowering the Optima settles its centre of gravity and trims the body roll that makes the standard car feel reluctant to turn in. With 720 damping settings on tap, you can run softer rebound for broken UK tarmac during the week and firm things up before a track day without changing a single component. The front end gains the support it needs to keep the nose from pushing wide under braking, while a flatter platform gives the front tyres a more consistent contact patch mid-corner. Stance improves too: pulling the body down into the arches transforms how this generation of K5 sits on the road.

About the Street Advanced coilover

The Street Advanced is the kit XYZ Racing’s engineers have refined over several years, and it sits as their most popular all-round coilover. It carries 720 damping adjustment positions, so compression and rebound behaviour can be matched to road, weather and tyre rather than locked to a single factory compromise. XYZ Racing developed and validated the platform through international race programmes before releasing it for the street, which is why the same kit is rated for both daily commuting and track day use. Ride height adjusts across the strut body, letting you balance kerb clearance against the stance and handling you are after. For a driver chasing more speed and sharper control from the K5 without giving up everyday usability, it is the natural starting point in the XYZ Racing range.
