Mostly Stock with SSR Type-Cs

SSR Gunmetal Type-C 16x7.0 ET42 (12.1 lbs)
Yokohama db Super e-spec 195/55R16 (19.0 lbs)

I started a thread about these wheels earlier and you can check out some more pictures of them here:

I took some more pictures with the center caps installed:

The wheels are machined to accept a snap-in retaining ring to hold the hub rings in place. Pretty nice…

Overall, I love these wheels. You can absolutely feel the difference in weight and I can’t recommend them enough. Not to mention they look really good on this car too…

GE8 Cylinder Head Assembly & Intake Runners

I came across a used Honda Fit (GE8) cylinder head assembly on eBay and contacted the seller about whether they came with the cams, rockers, valve, etc. or not. I ended up getting the cylinder head, GE8 cams, GE8 intake plenum, intake runners all for $650 shipped from MN to FL. I’m looking into extrude honing the head and runners, but I may try to port it myself by hand. I’m going to practice on another manifold first to see if I have the capacity to reach everything.

I took some pictures showing the exterior as well as some internal shots of both pieces that I’m going to extrude hone:

Kind of a cool shot...

Alternate Wheel Set: Racing Hart CP-035

I came across these wheels used on eBay and remembered seeing them on the wheel weights list as one of the lightest wheels made. 13 lbs. for 17x7.5! They are discontinued and are pretty rare. I wanted to have another set of wheels so I can play with some wider, stickier tires. The fitment was perfect for the CR-Z, so I made an offer and he accepted! They looked pretty dirty in the pictures, but no curb rash or major damage. I got them safe and sound, and with a little elbow grease I was able to get them pretty clean. Two of the tires are 60% and the other two need to be replaced. I’ll probably replace all four and sell the two usable ones. I’ll probably sell my stock wheels now too...

Anyways here are the specs of the wheels and the tires I want to run:

Racing Hart Winning Gold CP-035 17x7.5 ET50 (13.0 lbs)
Yokohama Advan Neova AD08 215/45R17 (22.0 lbs)

And pictures:

These pictures were with no spacers.

In your first thread about the ssr rims on the picture where you weighed them on the scale they were 11.9 not 12.1 just curious as to which is the correct number? Btw what is the weight of the stock 16' rims?

Nice car man your build is one of the ones I follow because you have the same idea as to what a "sport hybrid" should be

My scale says 11.9 lbs, manufacturer says 12.1 lbs and I only weighed one of them. Stock weight is 16.5 lbs. Thanks for the compliments!

Red Vinyled Honda Emblems & Spoon Motor Rib

I vinyled my Honda emblems today and took some shots with the hood open to show the Spoon Motor Rib that I installed a few weeks back. You can also see the Spoon oil cap in the last shot as well.

The red vinyl isn't quite "Honda Red", but for the money it'll do for now. I'll figure out a better solution later...

I want a spoon rib :( Jealous!! Those SSR's are money bro. You should sent that Cylinder head to golden eagle and get it bored/sleeved out. :thumbup:
I think you're thinking of a cylinder BLOCK for sleeving/boring. I have a cylinder HEAD; to which I want to extrude hone along with the intake runners.

Yeah, I like the Spoon Motor Rib a lot. Not sure how much it helped, but at least it looks tight! My only gripe is incompatibility with some SRIs. I'm going to try to see if I can get it to work with the Takeda intake with a little trimming to the filter housing.

Thanks for compliments!

Black Seats, Black Center Console and Base Model Trim Pieces

I've kinda been neglecting my build thread for awhile. I've been doing mods and taking pics, but I never got around to posting them or it was just better suited as a DIY. Anyways, here is my favorite mod that "really ties the room together."

I love the OEM Honda Black seats with the blue stitching. While I don't mind the gray seats, I feel that black seats would show less dirt plus I think the blue stitching is a really sharp look. To get black seats for a reasonable price I would have to get them used either from someone replacing theirs or from a wreck. I figuring the chances of that happening locally or at all, given the rarity of black seats, are pretty slim. I decided to just reupholster my own.

I bought the fabric from Honda for about $800 or so. I have the service manual, which details how to do this, so I just went at it. I also added the BASE model trim pieces at the same time. Here's the pics:

Taking the seats apart...

Removing the fabric from the cushion.

These are the upholstery rings or "hog rings" that need to be removed in order for the upholstery to come off.

I used a pair of pliers to pull them apart. This is the hard way to do it. Hog ring cutters would have made this job so much easier.

Instead of hog rings, I secured the upholstery with zip-ties. These are much easier to remove without specialized tools plus I already had them.

It is a little tricky to get the zip ties to make the bend without poking into the foam. I used a trim tool to guide them under the rod.

Seats installed in the car.

Another shot of the seats. Also seen are the BASE model trim pieces: the Alumium finish pieces around the front cupholders and the black door handles. I always felt that the EX gunmetal trim peices were a little out of place...

Another shot of the seats with some sunlight to highlight the blue stitching.

Close up of the BASE model trim pieces on the black center console.

Spoon Suspension

I installed Spoon springs and struts awhile back and I'm finally posting some pics. Here they are:

Spoon boxes make me happy...

All unboxed. The FSB still has yet to be installed...

Ready to go on the car. The rear sway bar is the Basis V1 which rubbed; came off after two days. No thanks...

Car on the lift.

Knuckle supported by my floor jack. I don't want the drive shafts coming out...

Comparing the Spoon strut with the OEM strut.

Shot of the rear spring and shock.

Other side shown with the ARK exhaust.

A day or so after lowering.
