BC Racing Coilovers - 03-08 Mazda 6

Application: 03-08 Mazda 6

This listing puts the available BC Racing options for this fitment in one place so you can compare them without bouncing between separate products. BC builds these kits around application-specific spring rates, and several series can be ordered with custom rates or Swift spring upgrades where applicable.

Available options:

• BR Series - 30-click single-adjustable mono-tube. Independent ride height adjustment. Custom spring rates and Swift spring upgrades are available on applicable orders. Why you would choose it: Best for most street cars, weekend canyon runs, and track-day builds that want real adjustability without getting overly complicated.
• DS Series - 30-click single-adjustable mono-tube with a digressive piston for stronger low-speed control and crisper response. Why you would choose it: Choose this when you want sharper turn-in, better support in transitions, and a more aggressive feel than a standard linear-valved setup.

Simple version: BR is the easy all-around answer, DS tightens the car up more, ER/HM/ZR/ZX are for builds chasing more track control, and RM is the inverted-strut option when that matters for the chassis.
