Hey, long time lurker, first post here. Picked up my 2018 Fit EX 6 speed CPO from my local Honda dealership at 14.5k miles this past August. This car has been the perfect balance of a single car for me; it's fun, cheap, low maintenance daily, cargo hauler, and autox platform with great potential. My current goal is to achieve the perfect balance of cornering performance while meeting a certain standard of daily drivability.

So far I have done only 1 autocross event with the only modifications being short shifter and throttle pedal spacer. It was nimble and maintained surprising front grip despite the awful stock tires. The autocross I attend is not a club autocross; it is open class, no restrictions, and thus not officially competitive. For me it's just about improving my driving, improving the car, and having fun. From what I've seen, this is a great community and I'm eager to share knowledge and learn more about the platform!

Here's the current build:

• Interior
  • Acuity Throttle Pedal Spacer (an absolute necessity)
  • WK Motorsports short shifter kit
    
• Exterior
  • Roof rack with Yakima tracks, towers, and roundbars, custom installed by a local rack outfitter.
  • 
    Yes, this is a permanent rack system attached to the roof's sheet metal
    
    The tower and bars are detachable though
    
    These kayaks are 50lbs each. I've never felt uncomfortable driving with them on the car.
    
    This is how it looks with the racks removed
    
• Wheels & Tires
  • Stock EX wheels & tires for winter set
  • Work Emotion CR Kai 15x7 +44 with Bridgestone Potenza RE71R 205/50R15 tires
    
    
    
    I was afraid these would look small on the car, but I think they look great now. If only it was a little lower...
    
    This is how much a stock wheel/tire weighed.
    
    Weight of the CR Kai's/RE71Rs. The CR Kai's are kinda heavy. I thought they would be lighter than this, especially because of the smaller overall diameter. From what I read, the wheels themselves in this size are around 16lbs each. RPF1s in the same size are almost 10lbs each. Definitely want to go lighter in the future.

I suppose I'll update this post as needed, at least until the build is at the point I want it. I am soon doing SPC front camber bolts, Motul DOT 5.1 brake fluid, and Stoptech Sport pads on the front. Debating on Progress rear sway bar. Still debating on what to do about springs/dampers - I'm considering the HFP suspension kit because it's streetable and cheaper than a full coilover system. It would be nice to have adjustable damping/ ride height though...

Anybody else autocross their GK5?

 

I can tell this is going to be a thread to watch. Could you go into more detail about your pedal spacer? What about it do you like/ dislike? And do you have a picture? Thanks, man.

 

Hey I appreciate it. I feel like the Acuity spacer is the first thing you need to do to these, and I believe Acuity is the only company that makes one. The stock pedal setup has the throttle pedal too close to the firewall relative to the brake, which makes trying to heel toe awkward. The pedal spacer just makes the pedal closer to brake pedal and driver so the brake and throttle are more level. I tend to heel toe on light (street appropriate) braking when I need to downshift, so with the spacer I can have more control over the throttle blip. There isn't anything to dislike about it though. Well worth the $100.

Here's some pics of when I installed it a while back:

 

Camber bolts installed the other day. Easy job. Aligned at Firestone, alignment sheet in the last picture.





The -1.6 degrees is the max I could get with both sides even.

 

I also recently figured out how to show torque pro measurements displays on the touchscreen. I really love this feature. Without this I would have to get a phone mount on my windshield and need to look at the phone screen, which seems like a waste of a perfectly good display built right into the car. I'd highly recommend doing this to anyone who cares about monitoring precise OBD readings.


Monitors for: Engine RPM, Coolant temp, intake air temp, engine % load, mpg (instant), mpg (avg), afr, lambda, and obd vs gps speed difference

@ Evergreen speedway up in Monroe, WA. Air temps were low 40's.
Open class autox - I placed 4th out of 9 FWD, 3rd if last run was clean/ drove solo more than once.
Just some good tires and small amount of camber up front. Open diff kept spinning with the slightest amount of throttle when the inside wheel picked up, which was pretty much all the time. I'm thinking coilovers and a RSB should help with that.
Also this time disabled traction and stability control which would always cut power on wheel spin and it was still very controllable.

 

Can't wait to get involved in the local SCCA autox events!

 

Right on
