    Hey everybody. I’m looking at buying an RS soon and one that I am considering has had some modifications done. Should I be worried about reliability. I’ve never modified a car before so I’m not sure what effects reliability and what doesn’t. I’ll provide a list of the modifications below. If...

  4. Focus RS TroubleShooting
    Have the dreaded p0171 code but common solutions don't seem to fix the problem or make sense in my case. Car has catless downpipe and larger intercooler, both have been on the car for about 18 months. No code. Few months ago had what seemed like a misfire, pulled up to a stop light and car...
  5. Focus RS TroubleShooting
    Hi, I’ve been having this issue for a while and it’s gotten to the point where I’m considering getting rid of the car. The issue is that when I’m cornering this car slips like crazy. Im barely on the throttle and I feel the back end slide out and then the front end. It kind of oscillates back...
  6. Focus RS TroubleShooting
    Hey guys, I have an issue that arose about a month ago. Whenever I steer at low speeds and idle, I get a very loud, what sounds like a rubbing or grinding noise. I haven't been able to pin what it is, closest i got was its on the passenger side of the steering rack, couldn't tell if it was the...
  7. Focus RS Brakes
    Hello! I am not a mechanic but I thought changing my own pads and rotors wouldn’t be so bad in the garage. I’ve done it before on trucks and it was never too bad. Anyways, I started with the rears, got the caliper and hanger off pretty easy on the passenger side but the spring on the driver side...

    Hi, (obligatory its my first thread!) I don't have an RS quite yet, I'm just currently looking at them as an upgrade to my 2016ST3. I was looking at a 2018 limited RS at a dealer yesterday and from afar it looks like a good deal. Its low mileage (47k km or about30k miles) its advertised at $47k...

    New owner here; had the car about 2 months (2016 NB 41k miles - ETS FMIC/Mishi intake/silly boomba BOV/ COBB tune+ 93) only driven weekends and really nothing abusive.

    I'm currently in the process of buying an out-of-state 2016 Focus RS with 57k miles and is in immaculate condition. But, I have no way of telling if the head gasket has been replaced with the C gasket or not. CARFAX doesn't say it had, and when I called Ford's customer service I was told that my...

    Chopped Muffler / stock pic for comparison Focus RS The dealer says they are replacing the muffler, but i am not sure its worth getting if that and other issues are present. As someone who is not planning on modding so i am a bit out of the loop on what to look for in a modded car. It is also...

    Hey all, I am new to the car scene in general and I'm wanting to get lowering springs and drop to 18's (currently fully stock 2016.) I have 0 knowledge on how fitment works and how springs work as well. As I read descriptions of springs I see mixed length of drop like "1/2 to 5/8" or "~1" or...
