Its time for me to plumb up the brake system on the Midlana. I'm using NA8 front brakes and Hard S rears. To make future maintenance as easy as possible I am trying to use "off the shelf" OEM parts rather than custom made parts. For the flexible brake lines the obvious choice would be Miata parts, however with the Midlana's wide front stance I suspect they may be too short. I need 16-18 inches of flex line for the front brakes, and from what I have been able to find online the factory front lines are closer to 14 inches. Can anybody verify that?
Are there any other cars that use the same size banjo bolt and M10x1 flair fittings as the Miata? I know there are extended lines available for the drift crowd, but those are more a custom part like I am trying to avoid, and also availability seems to be limited due to COVID.
The rear lines don't need to span as far, however I am planning to locate the distribution block at the center of the car instead of on the passenger side. Any reason not to just run two driver's side lines?
Thank you!

For my 55 Ford disc conversion I used RockAuto's info to determine flex brake line specs (lenght, and thread sizes)
Accounting for full lock I need an 18 inch flex line. Rock auto says the OEM miata lines are only 14.5.
Any ideas on OEM lines that might share fittings with the Miata?
Sunsong has a really nice online catalog, with all the features (end type, fitting thread size, length). And also the OEM application.

The O'Reilly system can filter by brand, overall length, fitting size, fitting style, etc. Unfortunately not their website, just their counter system. You'd have to find an employee you don't want to bash their head into the counter talking to though.
I just measured a set of Goodridge braided steel lines that I got from Mazdaspeed many years ago and the long pair (I assume fronts) are 16" overall.
Also, these guys say theirs are extended lines....Extended Stainless Steel Brake Lines - Front (zerekfab.com)
Or Treasure Coast has even longer....Techna-Fit Stainless Steel Brake Line Extended Front Lines Kit for 1989-2005 MAZDA MIATA MX-5 - FREE SHIPPING (treasurecoastmiata.com)
The front lines on the Sport brake cars (2001-02 Sport models, all 2003-05) are longer than previous Miatas. That's what the "extended" lines are. Get yourself a set of factory lines for one of those if you want OEM. Sorry, I don't have the dimensions handy.
The rear lines are the same on both side. There's steel going from the junction block to the wheel well.
for my Locost 7, I wanted to use a premade hose and was able to design the car to use the same hose for front, back and also for the clutch. Bolts on to stock banjo bolts and uses standard flare on the other end. They are also DOT rated. So far they have been great and no complaints.

That is exactly what I was looking for. Thank you! You have to really give a narrow length range or it says "too many results". In the 16-16.25" range it looks like the following might work:
2204866 from a 2002-2004 Nissan Frontier at 16.1 inches
2203965 from a 1994-1998 Hyundai Sonata at 16.14 inches
2201408 from a 2007-2008 Honda Fit at 16.2 inches
2202825 from a bunch of mid '00 Lexuses (Lexi)? at 16.23 inches
