Infiniti G35 BC Racing Coilovers

Built for the Platform That Earned the Reputation

BC Racing coilovers for the Infiniti G35 are one of the most popular suspension upgrades for the V35 platform, offering adjustable ride height, damping control, and proven performance for street, drift, and track builds. Designed specifically for the Infiniti G35 chassis, BC Racing coilovers improve handling response, reduce body roll, and give owners the ability to properly dial in stance and suspension feel without sacrificing everyday drivability.

The Infiniti G35 arrived on the V35 platform with genuine rear-wheel-drive sports-car credentials and a VQ35 engine that enthusiasts have been building around ever since. It also shares that platform with the Nissan 350Z, which means the G35 coilover market is deep, competitive, and well-supported. BC Racing G35 coilovers sit at the centre of that market: tested specifically on the platform, available across multiple series, and built with the kind of detail that makes the difference between a coilover that fits and one that actually works.

What Makes BC Racing Coilovers G35 the Right Choice

The G35 coupe and sedan are distinct fitments, and that distinction matters. Both are covered at Springrates, including the True Rear coilover configuration. On the G35, the factory rear suspension uses a divorced spring-and-shock arrangement rather than a conventional coilover setup. The True Rear option replaces this entirely with a full coilover unit, giving you proper spring-rate control, improved rear-chassis response, and a cleaner overall setup that the standard configuration cannot match.

All G35 BC coilovers use a 53mm monotube damper body with high-quality damping oil that maintains consistent performance across a wide temperature range, whether that comes from climate or aggressive driving. Height adjustment is independent of spring preload, thanks to BC Racing's patented concave lower locking ring, which retains full suspension travel at any ride height you choose. The standard drop on BC Racing G35 coilovers delivers approximately 1 to 2 inches below factory ride height, with the Extreme Low option extending that to 2 to 3 inches for drivers seeking a more aggressive stance.

Three Series, One Platform - Choosing Your BC G35 Coilovers

BC Racing G35 coilovers are available in the BR, DS, and ER Series. The BR Series provides 30-way simultaneous compression and rebound adjustment with carefully chosen spring rates that avoid the oversprung feel common in competing products, making it the strongest all-round starting point for daily driving and occasional track use. The DS Series adds digressive piston valving for sharper low-speed damping and better body control through weight transfers, suited to drivers who track the G35 regularly and want more precision from the platform. The ER Series provides independent compression and rebound adjustment via external reservoirs at all four corners, giving active track drivers session-by-session tuning control without the limitations of a single dial.

One practical note specific to the G35: the rear strut tops are enclosed rather than accessible in the boot as on many other cars. On BR and DS Series kits, this means adjusting rear damping requires removal. On the ER Series, external reservoir placement allows easier trackside access. An alignment is required after installation on any series.

At Springrates, we have been an authorised BC Racing retailer since 2005. If you need help deciding between the coupe and sedan fitment, the True Rear option, or which series suits your build, reach out and we will get on the right track.

Frequently Asked Questions

Do BC Racing G35 coilovers fit both the coupe and sedan body styles?

Yes, but they are separate fitments. The G35 coupe and sedan use different suspension configurations, and BC Racing produces specific kits for each. When ordering through Springrates, select your exact body style and model year to confirm the correct kit. The coupe covers 2003 to 2007 on the V35 platform, while sedan fitments span a slightly different range. If you are unsure which kit applies to your specific car, contact us before ordering and we will confirm.

What is the True Rear coilover option for the G35 and why does it matter?

The factory G35 rear suspension uses a divorced spring-and-shock arrangement, meaning the spring and damper are separate units rather than a conventional coilover design. The True Rear BC Racing option replaces this with a full coilover unit at the rear, giving you proper spring rate tuning, genuine rear ride height control, and improved rear chassis response that the standard rear configuration cannot deliver. For drivers building a serious performance or stance setup on the G35, the True Rear option delivers a meaningful improvement over the standard rear fitment.

Are G35 BC Racing coilovers compatible with the Nissan 350Z?

The G35 and Nissan 350Z share the V35 platform and VQ35 engine, and there is significant crossover in suspension fitment between the two cars. However, fitment is not always identical and depends on body style, model year, and the specific kit. Always confirm fitment using the vehicle selector on the product page for your exact car rather than assuming crossover compatibility. If you have questions about a specific application, the Springrates team can confirm before you order.

How do I adjust the rear damping on BC G35 coilovers without removing the struts?

On the G35, the rear strut tops are enclosed rather than accessible through the boot as on many other platforms. On BR Series and DS Series kits, adjusting rear damping requires removing the rear struts to access the adjustment dial. This is a known characteristic of the G35 platform and affects all brands, not just BC Racing. On the ER Series, the external reservoirs house the compression adjuster separately, allowing it to be positioned for easier access depending on installation. If frequent trackside damping adjustment matters to you, the ER Series is worth considering specifically for this reason.

What drop range is realistic with BC Racing coilovers on an Infiniti G35?

Standard BC Racing G35 coilover kits deliver approximately one to two inches of drop below factory ride height. The Extreme Low option extends that to approximately two to three inches for a more aggressive stance. Factory ride height cannot typically be achieved once coilovers are fitted. The exact drop achievable depends on your wheel and tyre fitment, so factor clearance into your planning when choosing between standard and Extreme Low configurations. An alignment is required after installation, regardless of the selected drop amount.

Which BC Racing series is best for a G35 used for drifting?

For drift use, the DS Series is a strong starting point due to its digressive piston valving, which produces sharper low-speed damping control during the sustained weight transfers and direction changes involved in drifting. The ER Series, with independent compression and rebound adjustment, gives experienced drift drivers the ability to tailor their setup for entry, mid-corner, and exit behaviour - a meaningful advantage at higher levels of competition. Custom spring rates are available on both series at no additional cost, and for drift applications, front-biased spring rate configurations are common. Contact Springrates to discuss spring rate options specific to your drift setup.

Can I upgrade to Swift Springs on my G35 BC Racing coilover kit and is it worth it?

Yes. Swift Spring upgrades for BC Racing G35 coilovers reduce unsprung weight while maintaining more consistent spring rates throughout the compression range. For a G35 used on track or in drift applications, reduced unsprung weight translates to faster suspension response and more consistent tyre contact. If you are switching to a significantly different spring rate alongside the Swift upgrade, revalving the dampers is recommended to ensure the spring and damper work together correctly. Swift upgrades can be specified at the time of your original order or added to an existing BC Racing kit. Contact Springrates to confirm sizing and configuration for your specific fitment.
