XYZ Racing Circuit Master Coilovers — Nissan MARCH K13 TYPE1 (Modified Rear Integrated) 2010-2017

The K13 March’s kerb weight barely clears a tonne, and that lightness is exactly why Japanese time-attack and gymkhana grids are full of them – but the standard torsion-beam rear and soft factory dampers waste that advantage the moment the road gets technical. XYZ Racing’s Circuit Master coilover for this Type1 rear-integrated K13 chassis is built for sustained circuit lap-time work rather than a fast-road softening.

For a car this light, spring rate and damping control do more work per kilogram than on anything heavier in the class, and Circuit Master is the range built to exploit that: full-range height and damping adjustment aimed at drivers running the March on track days and club circuit rounds rather than the school run.

What this coilover does for your 2010-2017 Nissan March K13

Fitted to a 2010-2017 March K13, Circuit Master drops ride height and firms up body control without turning the car into a kart on the road home from the circuit. The 9720-position damping adjustment, delivered across the coilover’s three external knobs, lets you separate compression and rebound enough to tune out the March’s factory nose-dive under trail braking, and firm the rear enough to stop the torsion-beam axle stepping out mid-corner on a cold tyre. Ride height is adjustable, so you can drop the centre of gravity for track days and wind it back for road use. On a car that turns in as eagerly as the K13 does, the extra body control shows up most in mid-corner confidence rather than outright grip – you can lean on the front end sooner because the chassis stops moving around underneath you.

About the Circuit Master coilover

Circuit Master sits at the top of XYZ Racing’s range, built specifically for sustained lap work rather than road comfort. Each damper is validated by XYZ’s own racing teams on circuits internationally, and the spec reflects that: 9720 discrete combinations of compression and rebound adjustment across three external knobs give a resolution that a two-way or single-adjustable coilover simply can’t match. The trade-off is a small-orifice internal oil path in the damper body – on a genuinely rough section of tarmac or a kerb strike you may hear a faint noise as oil moves through it, which is a characteristic of the fine-adjustment design rather than a fault, and it has no effect on damping performance on the smooth, controlled surfaces this range is built for. That focus on lap-time consistency rather than everyday ride is what separates Circuit Master from XYZ’s fast-road and rally-oriented ranges.

Fitment for the Nissan March K13 (2010-2017)

This kit is built specifically for the Nissan March K13 Type1 with modified rear-integrated mounting, covering the 2010 to 2017 production run under chassis code NI19-1. Confirm your car matches the Type1 rear-integrated spec before ordering, since the wider March K13 range includes other rear mounting configurations that take a different kit.
