    I have a new set of front left and front right Koni Special Active Strut housings for sale. These are new, never installed, still in the box. They were shipped to me with some scratches, as seen in the photos presented. The manufacture part numbers are 8745-1336L, and 8745-1336R. They were...
  2. Koni Special Active dampers

    2010-2013 Mazda 3 & Skyactiv Suspension & Handling
    I installed Koni Special Active rear shocks and front struts on my 2011 3i. The original units clocked 55,000 miles, so were not worn out. The Konis, as advertised, improved both ride and handling.
  3. Koni Special Active Reds, backorder hell?

    2014-2018 Mazda 3 Skyactiv Suspension & Handling
    My apologies, I feel like I've been spamming this forum lately. Anyone have any luck ordering the Koni Special Active Reds lately? Specifically the rears (PN: 8045-1337)? I can't find them in stock anywhere and Tirerack just contacted me saying the back order is looking like late August at...
  4. WTB: 14+ Racing Beat/Eibach Springs or Koni struts

    Mazda 3 Parts - Buy / Sell
    Found some RB Springs, please ignore this. On the off chance someone is unloading some new/lightly used Racing Beat (ideally) or Eibach springs, I'd like to chat with ya. Not interested in H&R/Corksport as they are too low for my needs. Also interested if anyone has new Koni Special Active...
  5. KONI FSD - more comfort over stock?

    2014-2018 Mazda 3 Skyactiv Suspension & Handling
    I'm browsing all the discussion about the KONI FSD, but I'm not certain on what "better ride" means. My only real issue with the stock setup(2015 M3 sport) is on concrete roads. They have wavy pattern here, so the car is bouncing up-down at 2-3Hz - really annoying . All other cars we have a...
  6. New Koni FSD not lowering spring recommended

    2014-2018 Mazda 3 Skyactiv Suspension & Handling
    Just bought the new improved FSDfor my ride. Currently on eibach, but going to RB springs cause the ride is a bit low for where I live( unless eibach are much better ride/handling than RB, then I would keep the Eibach and be super careful). The dampers are on the way from Tirerack, I just got...

    2014-2018 Mazda 3 Skyactiv Suspension & Handling
    Had a shop installed vogtland and koni special actives on my mazda. Trimmed the bumpstops according to spring drop however it feels like Im hitting something on the rear when I go over bumps. Sometimes I hear a clicking sound. Ride is stiff but rides well on smooth roads. Small potholes aborbed...

    I am in the Maryland/Washington DC area. I posted on local craigslist, but wanted to get the word out so I joined the forum. Apparently I can't post the link since I don't have the post count. Feel free to message me if you are interested and I can forward you to the craigslist post. Selling a...
  10. Vogtland Springs + Koni FSD, 17x8 Wheels

    2014-2018 Mazda 3 Skyactiv Wheels and Tires
    I want to run a little lower than Eibach Springs and decided the 30/40mm of Vogtland/H&R would be a good look. I’m trying to decide on the best tire size for daily driving with the occasional spirited driving, with the help of everyone who knows much more than myself. I’ve done research using...

    Mazda 3 Parts - Buy / Sell
    $250 + shipping: Brand new set of Koni Sport Shocks for the first and second gen. Never installed. Sold the car and never got a chance to use these. Great deal on these rebound adjustable shocks that will take the handling to the next level and pair well with stiffer or lower springs. Was $700+...

    Looking for feedback on Koni Special Active Strut. Has anyone had experience with these yet? Relatively new (replaced FSD) so I haven't seen a review on these yet. https://www.koni-na.com/en-US/NorthAmerica/Products/Cars/Special-Active-(Red)/ Thanks in advance!
  14. Bilstein B6 or Koni FSD with Racing Beat springs?

    2014-2018 Mazda 3 Skyactiv Suspension & Handling
    Need a lowered and softer ride. I know the FSD will give me that, but the design just seems like it's begging for repairs down the road. I'd like to know if anyone has the Bilstein B6 and if it's more comfortable than the stock setup and how much drop it offers.

  16. Koni FSD Upgrade + Springs?

    2014-2018 Mazda 3 Skyactiv Suspension & Handling
    Greetings. I have a 2017 3GT 5-Door and I want to upgrade the suspension to Koni FSD shocks, and I would like to upgrade the springs as well, but I do NOT want to lower the car. The FSD page says that it is designed to run with the stock springs and does NOT lower the car. That is perfect...

    Hi, I am selling a set of used koni yellow sports that was on my car for about 30k miles. I am selling this because I am converting my car back to stock. Be aware! While removing the suspension, my mechanic noticed that one of the struts had some oil on top one of struts. He suspects it may...

    Hello, This upcoming week I'll be installing Koni FSD's on my car, I searched the entire thread and did not find many cases in which people have installed FSD's with their Eibach Pro Kit, I mainly found the RB Springs and FSD's Combo. My question is, will it be necessary to cut the bump stop...
