Seems like we’ve just received a leaked image of the Rocket Bunny 6666 Kit for the 2016+ ND Miata, made by the legendary TRA Kyoto. We can see that the design shifted a bit from their previous kits and they have some pretty awesome vented fenders and reuses the OEM Front Bumper which is pretty awesome by itself.

Wheels shown on the car are beautiful Rays TE37v (probably in 18″) that are 9.5″ wide with (minus) -15 offset! Now that totally makes an already aggressive car looks much more mean.

If you’re interested in ordering this full kit, just check out this page : TRA Kyoto Rocket Bunny ND Aero Kit.

It’s not just for looks!

The cutout in the 2016 MX-5 bumper right behind the emblem with an air funnel will feed air to the air intake and provide more power to the ND Roadster!

“When you look at the exterior, it’s a very natural, hard to notice part” says Garage Vary CEO.

After development, Integral Kobe checked gains from the duct design.

By using ventilation simulating the Miata traveling at about 40 to 50 km/h, they noticed gains of about 2.5 PS (~2.45 HP) and a small .4kg/m (~0.26ft/lb) torque increase. That’s on a vehicle equipped with Jet’s N-Zero Muffler for ND.

There is an effect on the power of the car. At higher speed, there also could be higher gains. It’s a functional part that does not require any engine modification. The small difference could be big on a circuit race with limited modifications allowed.

Price is going to be around $299. You can contact us at info@rev9autosport.com for more details about this part.

Garage Vary also says that there is something for the NC in the pipeline, should be similar in concept to this.

Hey everyone,

Integral Kobe has been testing intensively their ND for a few weeks and shared with us the results of their track testings. They do all tests in Central Circuit (https://en.wikipedia.org/wiki/Central_Circuit) as it’s close to the shop. 

First of all, let’s start with the stock vehicle (1.5L):

Here are the results from the stock car:

Then, he added High Performer Springs, Rays ZE40 Wheels (17×8 ; 6.8kg), ZII tires (215/40R17) & their N-Zero Exhaust (under development). Now, the new results:

The owner says that from his analysis, the tires & wheels helped for ~2 seconds, springs for ~2 seconds and exhaust for ~0.6 seconds. He believes better results will be possible with full coilover system!

This is all based on the 1.5L ND, so it’s good to see that these modifications really improve the lap times by A LOT compared to stock.

For those who don’t know, they own one of the fastest NC in Japan (2.3L with ~220hp) and he actually holds the record for the fastest cornering speed in its class in West of Japan. That’s mostly because of the aero parts they develop as well as their suspension components. Most of their parts are available at REV9 Autosport.
