04-13 MAZDA 3 BC Racing Coilovers - DS Type

Brand: BC Racing

Part number: N-03-DS

Note: If you are installing these coilovers on a 2010-2013 model year Mazdaspeed 3, you will need to purchase 2 lower control arm bolts for the lower shock mount. The 10-2013 Mazdaspeed 3 uses a shorter bolt that does not fit with this shock.

BC Racing Coilovers DS Type For The 04-13 MAZDA 3

Part Number:N-03-DS

BC Racing Coilovers DS Series is perfect for street driving and occasional road course duty. With easily accessible adjustment knobs for fine tuning your compression/rebound and separately adjustable ride height, having a performance coilover system couldn’t be any easier. You choose how low or high you want your vehicle, no preset ride height here, and patented concave lower locking ring keeps it locked in. Ride height is adjusted by raising and lowering the shock body; this maintains the same ideal damper stroke at ALL ride height levels for the best ride under any conditions. The pillowball mount option provides the most available feedback possible from your suspension and to sharpen your steering response. All this while providing a strong, attractive looking coilover system.

The DS series BC Racing Coilovers use a large 44mm diameter piston in a 53mm diameter damper body to maximize oil capacity. As the damper unit operates the oil contained within heats up. The viscosity of oil changes as it's temperature varies which can lead to changes in the damping characteristics of the unit.

BC Racing Coilovers use a very high quality oil with their coilovers but go that extra mile to maximise performance and build their BR range with a large 53mm diameter damper body. This increases the capacity of the unit which increases the volume of oil which in turn reduces the peak temperature and significantly improves damper performance.

Designed to Maximize Driver Feel

BC Racing Coilovers new proprietary digressive piston design offers increased damping force at low piston velocities while maintaining a linear damper feel at higher piston velocities. One of the greatest advantages of increased low-speed damping force relates to what the driver feels, e.g roll, pitch, dive, and quick weight transitions on technical road courses. This is the key difference between the BC Racing BR series and DS series, but makes the biggest difference where it counts!

Awesome suspension...but...

I have a 2012 Mazda speed3. I am a pro auto tech and the install on this system was what I expected...but....there are a couple of key items that the consumer should know about.
1. The lower bushing on the rear shocks is wider than the stock so your factory bolt with built in sandwich plate is not long enough to make thread. I had to cut on both ends. It worked just fine but come on...really! 2. The camber adjustment on the front, you can’t access the four Allen head bolts that secure the camber adjustment without drilling holes in the upper body mount. Luckily I’m used to being a master fabricator and made it work. I just thought other techs or especially the occasional do-it-yourself type should know that this isn’t a direct fitment for this vehicle. Once complete and tuned it’s a great system. Great ride But be prepared. To the BC engineers might want to key into these facts. For the cost of the system, fitment R&D needs to be dead nuts
