UK/Ireland Location: Other/NonUK. Posted November 17, 2019. Based on the information in Ecat / Etis the 320 mm front disc brakes were installed on the MK3 and early MK3.5 Focus ST. From production date 02-03-2015 onwards ford installed the 335 mm front disc brakes. The increased brake disc diameter was not because of performance reasons. yes, I figured it out. The camera was not working and I must replace the Start-Stop module. It it located behind the OBD port, check the image. If you have gray connector, you connected the camera and camera is not working, you probably have bad Start-Stop module and you need to replace it. The module has code something like: BV6T-14B526-xx. Wide Body Fender Flares For: Ford Focus ST Made from FRP Adds +50mm each corner Wheel Spec: 18x9.5 +22 with 25mm spacer **Not designed for Focus RS Front Bumpers **NOTE: Professional installation required. The Focus ST workshop manual specifies the torque as 12 Nm, which is approximately 106.2 inch/lb or 8.9 ft/lb. I use an inch/lbs torque wrench. Remember that for most torque wrenches, the upper half of the range is more accurate than the lower half. I suggest you do not use a ft/lbs wrench on spark plugs as it is highly unlikely any of them Our Ford Focus ST (2015-2018) front splitter is like no other. We actually extend the splitter underneath the car with ideal mounting spots. Our chassis mounted rod brackets stand out. We machine our splitter rods in house. Quality is key. The mazdaspeed 3 pcv valve (not entire plate) can swap right over. However you will need to adapt the hose size since the opening is much bigger. I have one sitting in my garage I was playing with for fitment verification. I did the same thing on my 05 Focus. Since the PCV valve is a wear item it's good to know the Mazda one is cheaper even 6tze.
