BC Racing Coilovers: Built for Your Car—Custom Fits and Swift Spring Upgrades
Mastering the Fit: BC Racing Coilovers Tailored Per Vehicle
Every vehicle has its own unique suspension geometry. That’s why BC Racing coilovers are meticulously engineered for the exact year, make, and model of your car. From damper lengths to spring rates, each component is pre-set on the assembly line for a direct replacement of your OEM suspension—no guesswork, no guess fit.
Coilovers: Built To Fit
All quality coilover brands—including BC Racing—commit substantial resources to tooling and product development to guarantee that their kits fit precisely for each vehicle type. In production, kits are assembled to OEM-replacement specs and shipped ready to install. This baseline ensures that you get:
- Correct ride height and damping travel
- Proper fitment with vehicle-specific top hats and bearings
- Confidence in fit and function right out of the box
Custom Upgrades: When One Size Doesn’t Fit All
Many enthusiasts and racers want to go beyond the standard setup. Premium brands like BC Racing, for years, have offered customization options such as:
- Custom spring rates (e.g. 8 kg, 10 kg, 12 kg)
- Swift spring upgrades
- Camber/caster plates and adjustable top mounts
- Extreme low setups
Traditionally, these customizations were offered courtesy to cater to a small niche of track-focused customers (e.g., drifting, time-attack). But as more drivers demand tailored setups, customization is no longer occasional—it’s common. That shift has impacted supplier logistics, delivery timelines, and costs.
Why Swift Springs Stand Out
History & Engineering
- Founded in Tokyo, 1997, part of century-old Tokyo Hatsujo spring tech
- Pioneering alloy “H5S.TW” and proprietary winding process delivers lighter, more linear, longer-lasting springs
Performance Benefits
- Thinner wire = less unsprung weight
- More spring stroke before bottoming
- Exceptional rate retention (within 0.5–1% after one year of racing)
- Faster reaction speed for improved road compliance
Swift upgrades are widely accepted across coilover brands and are a go-to for improved performance. And yes—a Swift option carries an upgrade fee—but it’s often worth every penny.
BC Racing’s Policy Shift: Courtesy Ends, Fee Begins
Effective June 30, 2025, BC Racing North America has announced a $150 custom build fee for any coilover customization—this includes Swift spring swaps, custom spring rates, extreme-lower kits, and advanced top plate adjustments . This change reflects increased costs in materials, shipping, tariffs, and labor:
- Dealers and consumers will incur the $150 charge
- Swift spring pricing is also increasing—$50 per pair retail, $100 for upgrades after June 9, 2025
While this fee helps stabilize base pricing, it also signals that customization is no longer light work—it’s a deliberate, labor-intensive engineering process.
What Customization Entails
- Disassembly: Coilover is removed from inventory and placed on the assembly table
- Spring swap or rate adjustment: Standard springs replaced with Swift or tailored by rate
- Setup changes: Lower ride height, extreme-lower internals, new top plates, caster/camber
- Reassembly & testing: Kit adjusted to customer specs, torque-checked, and returned to stock
This isn’t "free" labor—it involves skilled techs, bench time, and parts tracking. The new fee makes the process sustainable and transparent.
How We (Coilovers.com) Handle It
We absorb handling and processing fees on your behalf. You’re charged exactly $150, and we won’t mark it up further. That includes ordering, customizable options, and processing—all while maintaining top-tier customer support.
In short: you pay the fee, we do the rest—no surprises, no hidden costs.
Why Customization Fee Makes Sense
- Ensures customization is intentional: Customers think twice before opting in
- Maintains lead times: Prioritizing orders that truly need tailored setups
- Sustains quality: Covers labor, parts, and tech resources without inflating base kit prices
Final Takeaway
BC Racing coilovers deliver precision-engineered performance right out of the box for your exact vehicle. But when drivers demand more—whether it’s a sharper race setup, lower ride height, or Swift spring quality—that requires real engineering. With rising material and labor costs, BC Racing’s new $150 customization fee ensures these tailored builds remain high‑quality and sustainable.
At Coilovers.com, we stand behind transparent pricing: you pay the fee, we handle everything, passing no extra cost to you. For serious enthusiasts or track-driven builds, this is your chance to harness the full power of purpose-built suspension—all with clarity, confidence, and unmatched support.
