    2014-2018 Mazda 3 Skyactiv Discussion

There's a strange behavior regarding the braking system which I can't tell for sure that I had with my previous vehicles. When I shut down the engine, I can pump the brake pedal about...
  2. Wheel and Tire Setups for Track (3rd Gen)

    Hey folks. I just got a 2018 touring hatchback and was wondering what my wheel and tire options may be for track days and HPDE type setttings. I'm fairly experienced on the track so I am looking for something semi-aggressive and for track use only so I'm not too worried about rubbing issues...
  3. DIY rear motor mount for 3rd gen Mazda 3

    Mazda 3 Parts - Buy / Sell
    Filled a stock mount with 65 durometer urethane. Now, I will say that this mod will increase the NVH on the car significantly and that the driver's side mount (transmission mount) is a far superior albeit costly and labor-intensive mod. But this will also help lock down the drivetrain and really...

  5. Shifts in 3rd gear roughly, slight jerk. On first few shifts

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I have a 2015 Mazda 3 S trim sedan with 55k miles on it and I live in Oregon. I let it warm up for a good 5 minutes before I drive it everytime it has the blue symbol for the car being cold.

  8. 2.5AT issue from 2nd to 3rd gear

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    So this morning I drove to work, my 2.5AT was acting weird when shifting to 2nd to 3rd. The transmission would revs up about 700 rpm then up shift so there was a jolt after the rev. I wasn't sure if the torque converter was also slipping in 4th or 5th because I was paranoid and didn't want to...
