BC Racing coilovers are known for their performance, quality, and versatility—and that includes a range of customization options to suit your driving goals. You can upgrade to SWIFT Springs for superior spring technology, choose the Extreme Low option to achieve an even more aggressive stance, or request Custom Spring Rates tailored to your unique handling preferences or vehicle modifications.

SWIFT Spring Upgrade

SWIFT Springs are a premium upgrade known for their unmatched consistency, lightweight construction, and faster response. Made in Japan using proprietary materials, SWIFT Springs reduce unsprung weight while maintaining ride comfort and performance. This makes them a favorite for track enthusiasts and daily drivers who want sharper handling without sacrificing ride quality.

Extreme Low Option

For those looking to dramatically lower their ride height beyond what standard BC Racing coilovers offer, the Extreme Low option delivers. Ideal for show cars, stance builds, or vehicles with tight fender gaps, this upgrade includes shorter dampers and modified shock bodies to allow for significantly lower ride height without compromising damper function.

Custom Spring Rates

Custom spring rates let you fine-tune your suspension to your exact driving needs. Whether you're cornering hard on track days, hauling extra weight from modifications, or simply prefer a stiffer or softer ride, BC Racing can build your coilovers with springs that match your goals. Custom rates are especially beneficial for vehicles used in motorsports or those with aftermarket aero, roll cages, or weight distribution changes.
