Driving on factory stock track widths with a modern Renault Sport model means neglecting a vital part of its chassis capabilities. Under aggressive driving or track conditions, a narrow track increases excessive load transfers, encourages turn-in understeer, and reduces exit traction. Failing to widen your track setup means missing out on your vehicle's true potential and losing critical split-seconds along every driving line.
By installing these 17mm track-widening wheel spacers featuring a 5x114.3 PCD, you extend your axle track width by 34mm in total. You immediately gain greater stance, reduced body roll, and a significantly more aggressive look by aligning your wheels flush with the fenders.
The refined chassis setups engineered by Renault Sport deserve flawless stance and balance. Without adding dedicated hubcentric wheel spacers:
Engineered with strict machining tolerances and dual hub-centric centering, these 17mm wheel spacers eliminate all risks of wheel imbalance or steering vibration, even at high speeds.
No, this is strictly unsafe and strongly discouraged. The 17mm thickness reduces thread engagement inside the hub, creating a severe risk of mechanical failure or wheel detachment. Extended wheel bolts or a stud conversion are mandatory. A complete kit including these spacers and matching wheel studs and nuts is available in the complementary products section at the bottom of this page.
The 17mm thickness has been specifically calculated to offer the ideal balance between wide stance and dynamic performance without requiring any physical bodywork modifications on stock wheel setups.

Secure your wheel assembly layout and optimize track wheel centering with this heavy-duty Conic Wheel Nut 12x150 Key 19 - 23mm. Engineered specifically for performance vehicles converted to high-tensile M12x1.50 wheel studs, this 60-degree taper cone nut guarantees a perfectly uniform clamping load across the mounting face of your alloy or steel wheels against the hub.
An absolute requirement when swapping to lightweight motorsport wheels or performing wheel hardware maintenance during tyre changes, these premium nuts eliminate any risk of heat-induced backing out on your performance vehicle.
The hub interfaces and chassis components of track-driven performance cars handle massive shear stresses and lateral loads during aggressive cornering and high-deceleration braking cycles. Choosing to retain aged, rusty hardware with worn threads or installing generic low-grade nuts is a severe compromise to your vehicle safety. Fatigued lug hardware loses its tensile elasticity, rendering it incapable of holding the required torque setting. Without a systematic replacement using these fresh conic wheel nuts 12x150 key 19mm height 23mm, intense track vibrations can cause the lug assembly to back out over time. This loss of clamp load quickly causes micro-play, cross-threading, wheel stud failure, and ultimately leads to the wheel separating from the car at speed. You lose all steering control of your performance car, face high-speed impact risks, and instantly destroy your brake rotors, body panels, and suspension limbs.
A lug nut with damaged M12x1.50 threads or a deformed 60° cone seat will permanently damage your wheel studs and score the lug seats of your expensive aluminum alloy wheels. Neglecting to refresh your wheel hardware when installing wheel spacers or fresh track wheels leaves you vulnerable to permanent steering wheel vibration.
This open-ended tapered motorsport wheel nut is built to comply with the most stringent demands of track racing and rallying. Cold-forged from high-tensile Class 10.9 structural steel, it exhibits excellent tensile strength and fatigue resistance under load. A specialized zinc-nickel or chrome outer finish delivers an effective protective barrier against salt oxidation and withstands the high temperatures radiating from uprated big brake kits. The compact 23mm length and 19mm hexagon drive head allow easy access into deep, narrow lug holes without scratching your wheel paint finish. It is the mandatory item for your axle maintenance or to complete a high-end stance customization project on a sports chassis.
This conic open nut features a universal 60° taper seat design, making it perfectly compatible with alloy or steel wheels mounted onto M12x1.50 thread studs across the following popular applications:

What does a 60° conic seat mean and how do I know if it fits my wheels?
The conic seat describes the tapered base shape where the nut meets the wheel face. The vast majority of aftermarket alloy wheels (such as Speedline, BBS, Compomotive, OZ Racing) and factory wheels feature 60-degree conic lug wells. You must never mix a conic nut with a wheel requiring radius (ball) or flat seats, as it will back out immediately due to an improper contact patch.
What is the mechanical advantage of an open-ended 23mm nut versus a closed-end acorn nut?
An open-ended nut allows the wheel stud to pass completely through the top of the nut. This is strictly required if you run extended competition wheel studs or variable hub-centric wheel spacers; you will never be limited by thread depth, preventing the nut from bottoming out against the stud end before it can securely clamp the wheel.
The mechanical limits of your track car mean nothing without a flawless mechanical interface holding your wheels to the hub assembly. Never compromise your safety or wheel seating integrity with fatigued or low-grade hardware. Trust the strict quality control parameters of the Optimiz Access team to protect your chassis, and add your Conic Wheel Nuts 12x150 Key 19 - 23mm to your basket today.
