XYZ Racing Top Sport Coilovers — Lexus IS 200t/250/300/300h/350 (XE30) (Modified Rear Integrated) (Front FORK) 2013-2026

The XE30-generation IS carries a fair share of its mass over the nose, and left on the factory dampers it rolls into direction changes with more body movement than the badge suggests. Top Sport coilovers correct that lean without turning a daily-driven IS into a track-only tool.

Top Sport is XYZ Racing’s step up from a fast-road-only set-up: a track-capable spring and damping combination built around 30-50% more damping force, or roughly 2kg/mm more spring rate, than a comfort-biased street tune. For an XE30 owner who wants to drive the car daily and still turn up to the odd track day without swapping suspension the night before, that is the right amount of stiffness – enough to control body movement under load, not so much that the ride turns punishing on a B-road.

What this coilover kit does for your 2013-2026 Lexus IS 200t/250/300/300h/350

Fitted to the IS’s double-wishbone front and multi-link rear, the added spring rate keeps the nose from diving under trail-braking into a corner, so the front tyres load progressively instead of all at once. The extra 30-50% damping force controls the body through direction changes – less roll into the apex, less of the pitch you get from the standard dampers over a compression like a motorway slip road taken at pace. Ride height is adjustable independently of spring preload, so you can drop the IS enough to sharpen its stance and lower the centre of gravity without resorting to cut springs. Over broken tarmac the shock body itself is kept under control through sharp inputs, which is where XYZ Racing say the improved traction out of slower corners comes from.

About the Top Sport coilover

Top Sport sits between XYZ Racing’s fast-road Super Sport line and their outright competition kits. Spring and damping rates are lifted by roughly 30 to 50% over a street-biased set-up – or, expressed as a spring rate, around 2kg/mm firmer – which is enough to soak up the hit from an expansion joint or a mid-corner bump without the wheel skipping off-line. That control over the shock body is the point: on a car being driven hard, an underdamped shock keeps moving after the input has passed, and that residual motion is what costs grip. XYZ Racing built the Top Sport tune around what its own team learned running this exact type at track days, and it shows in how the car settles – stability under load is the headline, not outright stiffness. It is aimed at owners who do a handful of track days a year alongside regular road use, rather than a car that lives on a trailer.

Fitment for the Lexus IS 200t/250/300/300h/350 (XE30) (2013-2026)

This kit is built specifically for the XE30-generation IS, covering the 200t, 250, 300, 300h and 350 variants across the full 2013-2026 production run. It uses XYZ Racing’s modified rear-integrated mounting and a front fork-type top mount, so confirm your car matches this exact mounting configuration before ordering rather than a standard top-mount variant.
