I don't have a scale at home, but I have every reason to believe they are identical. When I get the opportunity I'll weigh it. To the hand, they certainly feel light, for what that is worth.
The seller, 88rotors, informed me they come from the same factory with just different caps.

damn I feel so gypped, my tracklites do have diamond encrusted center caps! Perhaps that is why they cost more!

I second the request for a weight! Also, for anyone running fenders, what spacers have you found that clear with 205/50 15 tires and a zero offset wheel? Mine look like I will still need a 5-10 mm spacer. |

I am gonna go to Harbor Freight and find a scale today  I think Exomotive has a spreadsheet with wheels and offsets. I think they said we need a 4mm spacer on the rears with the 15X8 holeshot. I'll try to find the spreadsheet. |

Mine look like I will still need a 5-10 mm spacer. This is a very timely question. I literally just ordered 5mm spacers yesterday. I started to mount my front fenders this past weekend. I run a 225/45/15 with the zero offset tracklites. There was a slight rub between the front tires and fender brackets. I probably should have waited to order the spacers until after I see what kind of interference issues I encounter with the rear fenders. I may need a different size spacer for the rear fenders. My perception from reading posts in this forum is that there is a higher probability of needing a spacer for rear fitment as opposed to the front. What kind of clearance issues are you encountering? |

Thanks for posting that Jon. I have a feeling the 5mm spacers I have on the way aren't going to be adequate for the rear 225s. |

The JNC wheels weigh a little more than 14 lbs from this crappy bathroom scale I have. So yeah, they are the same as the holeshots.

If I run a 5mm spacer in the rear, do I need longer studs on the hub with the holeshot wheels? Anyone know?

Any more than 5mm spacer, you would need longer studs. I feel very comfortable using the stock studs with 5mm spacers.

Fun fact, contacted an ebay seller, they claim the JNC 15 x 8 wheel weighs 19 lbs( specifically stated the wheel only, not shipping weight). I like your 14 lbs better:)
Mazda intentionally makes the front track narrower to cause understeer, by adding just rear spacers it should increase this effect. (Not including all the other things we have changed:). Stock front track 55.5, rear track 56.2 according to the book. I have never been a big fan of understeer! But you can make other adjustments to offset the track adjustments caused by just running spacer on one end of the car.
I have heard stories of Spec Miata racers finding wheels that appear the same, but different offsets, to be able to change the front/rear track ratio and not be noticeable to others. (not legal according to the rules)
The only clearance issue I have at the rear is with all the stock offset the tire rubs the frame on cornering and suspension bottoming. The front is happy with all the wheels I have tried. The fender bracket are another issue. Would love to somehow get the fender brackets(wings) to be quickly adjustable for different wheels. My rear fender will also barely touch the frame.

Some updates. Depowered the steering rack - was not that hard, except I broke a rusted snap ring and could not find a replacement locally. Mcmaster carr had one that fit in an english size. Also assembled the sub frames and replaced a brake caliper. I put a top coat over the POR15 on the subframes too. Came out decent.   Powder coated the floors, bulkheads, and trans tunnel to match the frame.    Replaced the oil seals on the transmission and rebuilt the shifter. The shifter now feels great! My engine should be back this week from the builder. I am excited to see it "new". Then my car can start coming together. |

Did you fill the turret before installing the shifter.. 90cc gear oil..

Yep! shifts like butter now! It was bone dry when I took it apart though.
