  1. 2014-2018 Mazda 3 Skyactiv Wheels and Tires
    I know the general rule of thumb is +-3% of dia or circumference is OK, but I'm wondering just how accurate that number is for this car. I've got a 2014 3i sport and want to upgrade the wheel/tire package for the summer. My current setup is the OEM 16" wheels with Conti PureContact 205/60's...
  2. 2014-2018 Mazda 3 Skyactiv Suspension & Handling
    Anyone aware of what is the diameter of brake piston in front and rear calipers? Japan built cars. Also looking for the diameter of the master brake cylinder. Want to do some calculations....
  3. Wheels / Tires
    Hi all I am considering putting 15 or 16 inch Steel (or may be alloy, something like Dots Dakar) on my 3 Sport. I am thinking 215s instead of stock 205s on a 7inch rim. Going for a wider to improve the grip and lower diameter of rim to soften the ride a bit due to extremely bad roads in the...

    Gauge install woes continue... After the heater hose adapter didn't work out, I purchased the sender adapter from Prosport, 32mm diameter. I did some research before and found that the radiator inlets were 33mm, so no problem right? Well I've been doing more research, and have been finding...
