Think a tune that elevates the rev limiter is safe and possible? Seems like if you did that, torque might fall below the NC for the remainder of the curve, but the extension of the power band would be helpful.

And now what happens if ND runs against NC with headers? Here is the overlay!

Green Line is 2006 with RoadsterSport Max Power Header, RoadsterSport Midpipe and RoadsterSport Q exhaust.
Red Line is 2016 STOCK
BLUE LINE is Project 2012 PRHT with our full Roadstersport Ceramic Coated STREET catted header and RoadsterSport Midpipe and RoadsterSport Q exhaust.

Analysis: stock ND does indeed run neck and neck for torque with NC when we give the NC our catted header that looks very much like what Mazda has now added to the ND. We should underscore that our NC with catted header in these results ALSO has full 2.5 inch exhaust back from the header back, while the ND is stuck pushing through stock small midpipe and muffler in this comparison... so not yet a fair comparison of ND vs. NC with similar exhaust configurations. And we also see that if we go catless on the NC with our RoadsterSport Max Power header then that is quite a bit more powerful than ND with stock exhaust system. Hopefully the ND responds well to catless header so it can re-take the crown here, hope to find out soon!

Testing numerous spring combos, first combo rather mild and yet the difference is AMAZING, the ND really comes alive once the soft stock springs are gone. And...it sure looks sexy once lowered!

Numbers upper part of page are STOCK, bottom of page after springs.

Thanks for the dyno posts! Finally, real world data. The ND looks great from idle to 6k; lots of torque. With a couple hundred fewer pounds to move it's going to do well in autox. Enjoy the development process and let us know about the new spring rates when it's appropriate (ready to sell).

I imagine you're going to do a big business in aftermarket springs for the ND. Car looks great in the second picture...

This always surprises folks, the power of WIDER wheel for the SAME width tires!

On the LEFT is STOCK 205/45/17 tires....and on the right is 205/50/16.

Thus, both tires are 205mm wide right? And given 25.4 mm per inch you have 8 inch wide tires in both stacks....yet the stack on right is more than 4 inches higher, a good inch per corner more effective width!

Part of what you see is the racy RE-71R is beefy for it's listed size, but MOST of what you see is effect of just spreading that 8 inch wide tire on 8 inch wide wheel. (stock wheel just 17x7).

Now to really blow your minds!

Even before the car was released we had MANY of you asking us to make a Caliper upgrade and wheel upgrade alternative to the factory $3400 factory upgrade price for Brembos and lighter BBS....and we listened!

YES, we have Four Piston Caliper Conversion Done that fits stock rotors and stock wheels!
YES, we have SIX Piston Caliper Conversion Done that fits stock rotors and stock wheels!
YES, two-piece rotor option in stock rotor size too!
YES, we have ND BIG BRAKE KIT Complete with Two-piece rotors.

AND ALL THESE OPTIONS LIGHTER THAN STANDARD ND BRAKES! Even our 6 piston caliper upgrade saves over 2 pounds compared to stock ND front calipers, and four piston option saves about double that amount! Even the Big Brake Kit is LESS weight than stock setup! The lightest setup stock size saves a big EIGHT pounds compared to stock standard front ND brakes per corner!!

YES...we have been VERY VERY BUSY!

Special thanks to Ryan and Mike the Machinist for many late nights this past 10 days to make it all happen! We are final test racing the caliper conversion this weekend! Note I won't answer all questions on this now, giving you guys the sneak peak, but FULL DETAILS on our site next week.

As for an amazingly light flow formed wheel to go with it, 14.05 pounds 17x7 with 40mm offset to be stock/street class legal.

Adding even mild springs has revealed that the ND does still have considerable cowl shake, so we are working on ND bracing already too!
