If you haven't been to our forum, you've been missing out on some of the fun! Ryan @ GWR has started his LFX V6 swap in his wild time attack Miata. Stay current with his build and all of our shop cars in the forum!


Konig comes to the Spec Miata party with a great looking NEW 15x7, 13.6 pound wheel named Current. The Konig Current has a great split 5 spoke look at an amazing price of $99! The Konig Current's +25mm offset is also optimized for Spec Miata racers.  
 
Although designed with Spec Miata in mind, this wheel is a great choice for street users looking for an affordable 15x7 wheel with a very aggressive offset.
 
NASA and SCCA Spec Miata rules require a 13 pound minimum wheel weight for competition and the object of that rule is to keep the costs LOW.  Rubbing and breaking wheels is common as racers rub against each other and drop wheels off track. 
NEW 15" Konig Hypergram in hard to find 15x7.5 and 15x8.5 
 
The all new Konig Hypergram is HERE! Flow formed for superior strength and low weight, the 15" Konig Hypergram comes in two aggressive fitments with the 15x7.5" ET35 and the 15x8.5" ET25.
 
Weighing only 11.6 lbs, the 15x7.5" ET35 Hypergram is perfect for STS competitors...and it can easily clear our big brake kits.  The unique 15x8.5" ET25 Hypergram weighs 12.6lbs and now is the WIDEST wheel you can fit on your NA or NB with factory diameter springs (stock or lowering). NAs will require a roll AND pull while NBs only need a flat roll to fit the 15x8.5 with 225/45/15.

Flow Force Injectors

If you are looking for superior idle quality but you do not need monster 1000cc injectors for your project, look no further! Flow Force injectors are based on cutting edge Bosch EV14 technology and every set of Flow Force injectors are f low matched within +/-1% static and dynamic (2ms pulse, idle conditions) flow rates for accurate fueling under every condition. All Flow Force injectors are plug and play kits including everything required for installation. 

Sean's Application Notes: These EV14 injectors are the go-to choice for high performance naturally aspirated builds, low pressure E85 forced induction, or a lightly built motor running pump gas with forced induction. With tight flow matching at 2ms pulse width, they will support 300whp on pump gas, and still idle beautifully. Bottom line there is no better value in the injector market and are a bargain at $299!

 
The wait is almost over, so we've activated pre-pay on the highly anticipated RoadsterSport MAX Power header for the 2016+ ND MX-5!
 
The results of going 4-2-1 on the dyno are clear, this is THE header for peak TORQUE on the ND with 2.0 liter motor.  Our Best DYNO Results to date are with this Header plus our RoadsterSport Midpipe and RoadsterSport SuperQ Muffler...and Tune which is critical to making the full TORQUE gains. Chart below shows comparison with baseline stock run. Notice new HIGH at the ground of HP 168 and BIG TORQUE 171 FtLb. If unfamiliar with reading DYNO graphs what you need to look for is before and after of same car, on same dyno, because what you want to see is the TOTAL GAINS. As you can see in graph below, our ND generation Miata totally stock did 139 hp at the wheels as a baseline from the factory (the factory hp rating is at the crank but you spend some of that number getting through the transmission and down to the other end of the car where the rubber actually meets the road). With this RoadsterSport Header, our RoadsterSport Midpipe and SuperQ Muffler we obtained our best torque curve to date with gains of 25+ ft/lbs over most of the rpms range, massive peak gains over 35 ft/lbs, and incredible 30 ft/lbs of torque gain from 3000 through about 4300. Result is SUPER meaty midrange where you actually drive the car, making freeway passing just a flick of the pedal, pulling away from stoplights is noticeably stronger than stock.
Our outlet is 2.5 inches.


 
 

ND RoadsterSport Mufflers 

All of our ND mufflers use new finely-tuned Helmholtz chamber technology to cancel out the 'boomy' droning frequencies so you get maximum fun without the negative side effects of typical aftermarket mufflers! All versions are in stock and shipping now:


Our mildest choice, on gas or off it is deeper and more throaty than stock and just a little more volume than stock. Also likely the best choice for those who later add header and/or midpipe that will raise the sound more. If the wife is going to object to anything too sporty, this is your choice!

Hear it:


Same overall design as the "Race" but upgraded with fancy tip for more full finished look and high density resonator to lower the volume. It's otherwise the same design and same melodic burble sounds when you put your foot to the floor, except it turns down the volume dial from 10 to about 7.

Hear it:





The MOST aggressive, minimal weight, minimalist look, not for everyone, will attract attention! Certainly the most fun for those not worried about sneaking out of the neighborhood early in the morning without waking the neighbors.

Hear it:


Big thanks to San Diego Miata Club Member Mark Booth for these videos!


Don't miss out on the next round of the Extreme Speed Roadster Cup at Streets of Willow Springs (CW) on May 29th!
