BC Racing Coilovers - 14-24 Mazda 6

Application: 14-24 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.
• RM Series - Inverted mono-tube strut design with 30-click single adjustment and independent ride height control. Swift spring compatible. Why you would choose it: Good fit when you want the added rigidity of an inverted setup without stepping all the way into a remote-reservoir package.
• ZX Series - 3-way adjustable system with 20 clicks of low-speed compression, 12 clicks of high-speed compression, 30 clicks of rebound, and external reservoirs. Why you would choose it: This is the race-car answer. It is for serious track or competition use, not the option I would push for a normal street build.

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.
