I had hoped to do something like this originally, but the FFR hatch hinge and bracket were in the way...

Nice job on the brake booster, also enjoying reading through your build thread.

No issues on the Bel Ray. It costs me more than I sell it for by the time shipping etc. is calculated in. Your source is the cheapest I have seen. I will likely pick some up from them also.

You are a freaking magician!! I really admire what you are doing, and how you are getting it done!
Your vision and execution are extraordinary, and I can't wait to see this thing done; but I am sure enjoying the build process, and the ride you are taking us on!!
Keep up the great work!!
Regards,
Steve

What year 350z roadster trunk hinge did you use to make your hinge? Looks good and really increases the hatch opening area.

Any of the US spec 350z roadsters/convertible, I think 2004-2008. NOT the coupe/hatchback. It's not plug and play, but really pretty easy to do with some simple welding.

I think I’ll steal that hinge idea.
update: I just bought a pair from eBay $18 shipped.

Thanks Dave I have the hatch on now but still not happy with fit so will keep working on it and may change the hinges as the ones you made seem to work great.

Damn, you have all the answers for this monster!
At times I wish I knew all of these solutions before starting my build. It makes me want to redo my car over and over.
Your hatch contour is pretty much perfect with the roof line.
Did you modify anything, or was it matched "out of the box"?

It didn't match perfectly out of the box. I think you are referring to this picture (I still have not made any adjustments after welding it in, may need to adjust slightly). The 350z hinges really control the position of the hatch leading edge. There is an adjustment screw built into the hinge as well that allows fine-tuning of the closed position. Before I installed the hinge, the driver's side leading edge of the hatch sat about 1/3" higher than it is in this picture. I placed a weight on that corner of the hatch to hold it symmetric to the passenger side of the hatch while I welded the mounting studs for the hinge to the GTM frame (hinge was already bolted to the hatch). Now it knows where to live in the closed position. The FFR hinges didn't have that control of position, too sloppy.

Yeah, I had the same experience.....here is a thread I started on that:

I ended up finding some in a box on the shelf here, so never did try to order any or find them to purchase....

Just about finished up the airbox. Not trying to win any beauty pageants since the outside will be covered with heat shielding.
Air filter is accessible, the red portion of the airbox will be held in place by screws/rivnuts.

Even back in '94 Honda was using variable resistors to control lighting, wipers, etc. So I'm having to tear switches apart and jump the internals to dumb them down a little.
I wired up the turn signals to a standard flasher relay and FYI for you guys planning on running LED lights on the corners, the LEDs don't draw enough current to make the flasher relay even work. Ordered some flasher relays designed for the low draw of LEDs:

All you need to do is put a resistor across the LED leads to increase the draw when in use. The LED specific flashers are the official way to do it, but the resistors are the cheap and easy way to do it.

Beeman,
here is a link to the load resistors that I used, for the led turn signal lights that were supplied by FFR.

Joel, are you running ABS? I'm running the OEM C5 ABS/EBCM so I'm not so concerned about front or rear lock-up, but there still may be some imbalance under track conditions. I looked through some of the C5 forums and usually guys are changing calipers to get more braking from the rear. Some of the C5 Track guys have ripped out the ABS and went with a Tilton/Wilwood setup. I don't think a variable proportioning valve is a great option in my situation as it would probably screw with the EBCM. I'm wanting the best option for street + track. Track only, I would probably ditch the ABS and booster entirely.

No ABS, no track and the stock Gen V Camaro dual Master Cylinder(1” bore) with Gen 5 Camaro SS calipers. The stock Tilton master cylinders are 3/4” front and 7/8” rear so if my math is correct this setup sends 16% more pressure to the rear calipers. So my thinking is to maybe put the proportion valve on the front brakes and that way I could create similar balance.
I have’t put much thought beyond that, but thought I’d ask since we are following similar paths.

With the larger MC on the rear brakes, that should make less pressure than the fronts......more fluid flow, less pressure. You would have to go to smaller MC size to increase pressure.....

Thanks so much Shane for adding your input. i’m Glad I have it backward, now it makes more sense with what I would need to do to get good brake balance. Dave, didn’t mean to hijack your thread and appreciate your feedback as well.

Continuing to mock up the console... I wouldn't dare build a C5 based kit without a manly DIC!

If you are considering tuning the GTM for the track
The proportioning setup from willwood is required.
I has stop tech custom build the calipers to match the weight bias and traction of the GTM. Even so the ability to adjust the bias really changes the turn in.
On the street it doesn’t matter at all. The GTM has so much extra braking capacity it’s silly.
On the track some form of bias adjustment is a must have.
The C5 although using the same components doesn’t drive anything like a GTM on the track. It’s apples and pineapples.

3D printing. Prototypes in PLA, final components will be carbon fiber reinforced nylon. How's your track car? Any updates?

Very cool. Yeah I’ve been busy updating my capabilities in the shop for the next phase of development. I need some robots to help me get the job done. Updates are coming soon.
