Logan's Gen 3 Coupe-R Build

[PNWTim]

I also really like the CF5. I ran that face-style on my Mustang for the past 3 years and absolutely loved them. Classic 5-spoke look, simple yet elegant, easy to clean... On the other hand I also like the look of the F14s, but it pretty much came down to available sizes that made that decision for me. SDC profile and 12" to 13" widths available in the F14, previously with as low as +6 offset, but now with UDC profile they go as low as -50 offset which is nice. I would not hesitate to use a spacer with CF5s or SDC-profile F14s if needed.

As for the hubs, remember the rear hubs (if you go with IRS) are already M14x1.5 studs as they are S550 Mustang spec. FFR would have you replace the beefy M14 rear studs to match their 1/2" studs in the SN95 front hubs... but I prefer to keep the larger of the two. Especially since it's standard issue on many (most) performance cars today. Better clamp load, higher yield strength, handles frequent torque cycles better, etc. To achieve this, you only need to ream out the front SN95 hubs to roughly the size of the rear hubs holes. There's science behind knurl diameter, material displacement, and so on. But long story short, I have done the science and have confirmed results. Buy a 0.612" diameter reamer from McMaster Carr, and within 5 minutes at the drill press you're ready to press in a 0.625" knurl-diameter M14-stud of any length you desire. The reamer is $50, and has little other use besides this, but very much worth it to do it right. Cuts the hub material like butter. Do NOT take a regular twist drill to your hubs!

Hello - I know this post is a couple of years old but I am curious if you had any concern regarding the "meat" left on the hub on the outermost portion after they were reamed out? I am guessing not as this hasn't come up but thought I would ask. Like you, makes more sense to go larger rather than smaller as I will be running 19's as well. Great build thread!

No concerns at all. The amount of material removed is minimal. Plus, in this specific assembly, you’re taking some steel out of the hub flange but adding the same amount of steel back with the larger knurled section of the stud. Using the reamer size I outlined is not a problem, and I have put dozens of cycles of 1.2G forces through them in real world testing. No fractures or failures observed.

Thanks for the quick reply. It makes sense, just wanted a real world double check.

ok Logan..... I am taking Command of your thread....lol.... need to get this to graduation!

Going to paint!

Pretty good weekend - I hate doing the carpet though!!!

What seats and headlights are those?

[Erik W. Treves]

kirkey that come with the kit; headlights are just off of amazon - same size that is on a jeep.

Hi Erik - what flasher unit did you use? I tried to pause and zoom in but couldn't identify it. I am assuming it was controlling the delay commands for each signal you demonstrated?

Not Erik but I know that the car has a Signal Dynamics self canceling turn signal module:

I've used these on several cars that I've built and recommended them to many other builders. They've all worked great with no issues. On the cars that I've built I have used different activation methods; a momentary rocker switch (actually a power window up/down switch), momentary toggles and individual momentary pushbuttons like what Erik demonstrated in the Coupe.

Thanks Jeff, I will look into.
