Gosh it looks so much better with the smaller diameter wheels. Can't wait to see it lowered -- soft springs always seems to be the weak spot.

Having the same hub pattern as NA/NB = winning!

In other news the used NC market should get really interesting soon.

Is the NC interesting at all at this point, or just as interesting as watching any market crash?

In for Pics of 225/50-15 on 6ULs. It can't be ugly or slow, or can it?

I test drove a couple NCs a while back. After owning an NA and NB, to me the NC is just ...different. I'd rock a PRHT as a DD but its not something where I'd dump a bunch of cash into it re:suspension/rims/tires/brakes. I/H/E is probably as far as I'd go, if that. IMO you have to like the NC for what it is, rather than as a Miata. But again, that's just me.

I will say the drop in option for the 2.5 (or is it 2.3?) MZR is rather attractive, that would probably be a frickin' riot.

<p>The NC is a fun car, that's undeniable. But it's a fun car for like... $10k. I genuinely can't imagine paying $30k for one, especially with the ND here. I'd happily pay $4-5k more for an equivalent ND. Maybe more. It just feels that much better.</p><p>&nbsp;</p><p>Funny though... I am not sure I like it better than my S2000. </p>

The shared hub pattern helps almost not at all. Different wheel sizes and offsets are needed for this car, so almost no carry-over there. Rotor hats need custom offset specs, so we could've done a 6-lug just as easy, etc. etc.

The ND has larger wheel wells than NA/NB. Tons of people *asking* for 15" wheels on ND, but likely they will all change their mind as soon as they see it. 16" wheel on ND is about the same proportion as 15" on NB. Don't worry, we will still give it a shot for you guys, but I suspect a year from now nobody will be putting 15's on this car, except for very specific cases looking for a gearing advantage in autox, much like 13" on NA.

Default Qualcomm autocross with ND

I'm sure Brian will be putting up some in-car videos. Here's one from outside the car:


Doh! Just realized that Brian wasn't driving...

After getting a quick feel for the ND on the street last week, I was itching to drive it at the autocross. This weekend Brian brought down the ND for more testing at the San Diego BMWCCA event. Today lots of fast SCCA and regulars were out to play, so it was an excellent chance to benchmark the ND's performance.


Prior to the event, Ryan finished up the 6 piston brake project and we mounted some fresh RE-71r tires (205/50/16) onto 16x8 Enkei RPF1s. Brian also swapped in an OEM LSD and some lowering springs for testing. Not completely stock but all the upgrades, except the tires, were very mild. Previously, Brian ran the car at an autocross the week before with stock wheels/tires and the LSD upgrade. Based on his results, he was predicting the car would be much faster after springs and some fresh tires.



On track I quickly learned the car was very soft, even with the lowering springs. You have to be patient with the car rolling onto the bump stops in order for it to go fast. The tires also made this worse, the RE71 has a crazy amount of grip and want way more spring than this car has currently. However, despite the body roll, the ND hauls and it was very easy to drive. In fact, the ND was just as fast as some of the local STR NCs which came to this event to prep for nationals. Ryan was able to get the 3rd fastest time overall (out of 80) and I was only .7 seconds off his pace. It is safe to say the speed potential is very high for this car.

I was also very surprised by the electric power steering in the ND, this was an aspect of the car I was unsure of. Thankfully, the steering was communicative and weighted just right, this made catching excessive amounts rotation very easy. Furthermore, the gearbox was very positive and never left you guessing what gear you were looking for. If I had to compare the gear box to another car, it reminded me of an S2000...only better. Another huge plus was the increased spacing between gates, second to third reminded me of the 5 speeds in NAs.



Finally, the motor in this car is an absolute gem. Combined with the gearing in the 6 speed, the numbers are a lie. The ND moves was faster than the 155hp would lead you to believe and the torque lets you could dig out of a corner with ease and short shift while still maintaining a very quick pace. Another common complaint I've heard is about the lower redline, after driving today I didn't find myself really wanting more. Again with the power band on this motor, you don't need to go for every last RPM and can go for another gear instead.

In summary, the ND is a Miata on steroids. It does everything a perfectly sorted NB2 track toy could do only better in every conceivable way out of the box. The speed potential for this chassis huge and reminds me the numbers do not tell the story. Mazda really did their home work and I'm excited to see the chassis to be developed further.

Looks like the Orange Virus guy might be an irl cool dude: Miata ND/Skyactiv Tuning Information thread - MX-5 Miata Forum

Big takeaways is how adaptive the ECU is, but the motor is essentially the same as a 2015 Mazda 3 2.0L motor with a different exhaust cam. Has a big warning about buying headers/exhausts and air intakes that have dubious testing if any since that can cause significant lean conditions up top more times than not. Also looks like there's a Cali specific ECU versus the Federal 49 state one.

Keith just mentioned that the 15x10 Jongbloed clears stock brakes on the ND.

That info has been out for a while, but its good to get more confirmation. I wonder how much (if any) bump you'll see going from the CA to the 49 ECU.

Wheels is one thing, but what's the fattest tires you can fit with close to the same diameter (i.e. a little taller than NA/NB)?
There might be more options in 17" than 15" (16" is always limited).

Probably the 235/50-15 R888.

I don't think a 15 is the way to go, i just found it interesting.

Something we are working on. We might be a bit late to the party but it should be worth the wait.

Looks amazing.

Can you replace the front emblem with the toilet bowl one?

Do what ever we want in CAD. Mazda is a partner on this project so no, we won't be messing with their logos.

Ah awesome, always good to see MNAO partner up with good race shops. So I take it that this is a Super25 project?

Very excited to have 949 diving into this new car as well. It's certainly not "late"! Renderings look great.
