  1. Civic Si in GS

    I have a 2018 Si Coupe and wanted to get into autocross so many thanks to all who post here! I've read all 72 pages and I'm surprised no one has mentioned reprogramming the car when the wheel sizes are changed. Background: When I bought my coupe in 2018, I bought the full Honda Factory...
  2. Seat covers

    I just bought this for my driver's seat. It covers the bolsters and stays in place well. This different from some of the other towel seat covers because it's made to cover the front and back of the headrest so it doesn't pull down when you set in it...
  3. Seat covers

    RobXsi, How do you like those seat covers now? Would you buy them again?
  4. 2018 Honda civic si HFP?

    I have a 2018 Si coupe that I added the complete HFP kit to, including the suspension. The upgraded dampers and controller gives a better ride with the OEM wheels and I autocross the HFP wheels which are lighter, with sticky tires. More of my thoughts and some pictures of the parts are in my...
  5. What's your SI looking like today?

    The HFP suspension package does not lower the car. It gives a better daily ride and a much better Sport mode.
  6. What's your SI looking like today?

    Yes, my HFP 19in wheel/tire comb is 4lbs lighter per wheel than my stock 18in wheel/tire combo.
  7. What's your SI looking like today?

    Thanks! The HFP wheels are made by Enkei and weigh 25 lbs. So my wheel/tire comb with the HFPs are lighter than the stock wheel/tires. 25 lbs may sound like a lot, but these are 19in wheels, so in the 19in wheel arena, they aren't heavy. The best thing about the HFP kit is what you can't...
  8. What's your SI looking like today?

    My Si with complete Honda Factory Performance package installed.
  9. Rally Cross Anyone?

    I hadn't heard of BPL. Seems like I've tried left foot braking in autocross to keep up RPMs in turns without any issues. I do autocross with VSC off.
  10. Coupe Si owners and seat belts...

    I get the passenger side seat belt clunking everyday when I pull into the parking lot at work. My windows are up, but its the side to side motion of going over the lip of the parking lot pavement. When I remember, I buckle the belt, but then someone rides with me and I get reminded the next...
  11. Now that summer is here, here's how to spot another Civic SI Driver

    For where you and I live, I think its absolutely the way to go. When I get in my hot car, the leather of the steering wheel actually feels hotter than the shift knob. The carbon fiber just doesn't transfer heat like other materials. The one I bought (pictured above) is a Mishimoto Carbon...
  12. Now that summer is here, here's how to spot another Civic SI Driver

    I bought my Si last July. I live in Tucson where its regularly over 100 degrees daily during the summer (which runs till Oct). I was carrying a bandana in my car to be able to drive out of the work parking lot each day. I thought how sad that looked in my brand new car. So I bought a carbon...
  13. DIY Manual Transmission Fluid Change and Are They Different By Model Year?

    Not sure why this picture was added to the thread, it does not belong here. The picture shows the remaining Engine Oil life, not the status of the Manual Transmission Fluid which is what this thread is about.
  14. DIY Manual Transmission Fluid Change and Are They Different By Model Year?

    For the record, my car is relatively new. My car only had 9,000 miles on it when I changed the MTF, which is way before the required maintenance interval. My car shifts better with the AMSOIL. BUT the point of this thread is how to change the MTF.
  15. HFP Package on 17 CIVIC SI

    I get the desire for a "lowered" look to the car. But when your actually driving the car with the full HFP suspension, its not missing anything. I autocross my car and with the HFP suspension, 19" wheels and PS4s, it handles great, has great grip and very little body lean. I had one of the...
  16. DIY Manual Transmission Fluid Change and Are They Different By Model Year?

    Agree, ramps work fine that's what I use. I measured the original fluid and 2 quarts came out. I added in 2 quarts of AMSOIL. Also, notice in my picture above that when you open the filler cap, it's not "full" meaning that gear that can be seen isn't covered in MTF - its not supposed to be so...
  17. HFP Package on 17 CIVIC SI

    The suspension package consists of new dampers, new damper module and new springs. I absolutely think its worth the cost. In regular mode with the stock wheels, the ride is much smoother. In Sport mode, there's less body lean. The install is pretty straight forward. The only PIA is the...
  18. DIY Manual Transmission Fluid Change and Are They Different By Model Year?

    The maintenance minder is only for the oil change. For MTF, just keep a record in your owners manual or on your computer/phone of when you did it and the mileage.
  19. DIY Manual Transmission Fluid Change and Are They Different By Model Year?

    Thanks for posting the link to the torque specs, that's excellent! I didn't notice any type of "liquid gasket" on my filler plug. Did you find any on yours when you changed your MTF?
  20. Rally Cross Anyone?

    I would be easier to remove the whole bumper/front facia with the lip, than the lip by itself. I don't know how over lips are designed, but the Honda HFP lip has an amazing number of bolts and fasteners holding it on. Some of the fasteners are like zip ties - I don't believe they can be undo...
