A trailer hitch with a difference.  Most aftermarket hitches you can buy are all the same, made from thick wall construction tubing, and way overbuilt for the lighter duty demands of your Miata.  Our hitches are completely 3D CAD designed and made of lightweight laser cut sheet metal and tubing, CNC formed, fixture welded then powder coated.  This is the only hitch available that's designed with weight and intended use as the major design goals. You can tow a small trailer (say, 4'x4' with your tires and tools) to the track. Once you're there, pull out the ball mount and the part that remains on your Miata weighs as little as 7lb!  These hitches are rated for a 750 lb trailer and 100 lb tongue weight - which is plenty to ask of your Miata's chassis and powerplant.

Install the hidden hitch body to the car and attach/remove the 1-1/4" receiver adapter piece when you want to tow or haul.  Super simple, no outward appearance changes, and the absolute minimum weight penalty!

The design is compact and is shaped to tuck away neatly behind the bumper cover, and doesn't interfere with the area reserved for the rear muffler.  Factory and nearly any other exhausts should fit without issue, unless you have an aftermarket center outlet design or muffler(s) that occupy a similar space.  Only a very small, unnoticeable trim of the plastic lower valence is required on the ND.  Some NB cars with Mazdaspeed valence or similar may require minor trimming around the removable receiver.

This diffuser was designed specifically for the NC Miata to do four jobs:

1. Improve aerodynamic efficiency
2. Increase downforce at the rear axle
3. Eliminate the bumper cover's "parachute effect"
4. Look fantastic while doing all of it

First the design envelope was established - we stayed mostly within the perimeter of the bodywork with only a small amount of protrusion beyond the bumper cover.  We weren't looking for maximum downforce or to install something we need to be careful not to trip over walking around the back of the car.  We wanted a sturdy, streetable piece that looks the part without going too far.  The main profile was shaped to gradually decrease the air velocity as it exits the rear of the car.  This helps merge with the slower air coming over top of the car, to achieve the highest performance within the design envelope. 

The lowest point of the diffuser is level with the lowest point of the rear subframe, so unless your car is really low there shouldn't be a huge risk for scraping the bottom over reasonable driveway entries..  That said, our steel mounting brackets are very sturdy and the diffuser body and strakes are made from 2mm aluminum.  The strakes CAN be replaced if you accidently damage one or two.  Lightweight yet very stiff, and only around 11 lbs installed.  The rear mounts of the diffuser are height adjustable for fine tuning.

Installation is very straightforward, uses factory holes and requires no drilling or permanent modifications.  Very easy with a hydraulic lift, doable on the ground.  Shipped disassembled to keep the package as compact as possible and also to prevent damage in transit.  Click here for the instructions.

All diffuser parts and mounts feature textured matte black powder coating - durable with UV protection to prevent fading over time.  All fasteners are stainless steel with black oxide coating.

This is a large piece and requires oversize ground shipping, via UPS or FedEx, depending on your location.

FTIMENT NOTES: This Diffuser is designed to fit all NC Miatas from 2006-2015, with the exception of the NC1's equipped with the "Appearance Package".  On NC2/3 with the cosmetic factory "diffuser/valence" at the bottom center of the bumper cover -- That item needs to be removed for the PacoMoto Diffuser to fit.  This factory valence piece comes loose with a few small fasteners, which can all be retained and re-installed if desired at a later date.  There will be five holes exposed in the bumper cover on these valence cars, and we will include plastic trim plugs to fill these holes with the hardware kit.

We’ve been offering our Eccentric Locks for NA/NB Miatas for a long time now.  They’ve become a staple in the Miata community from the casually-spirited drivers to the track warriors, keeping those precious wheel alignments locked-in. The tinkerers out there love the ability they give to make incremental adjustments to get the absolute maximum from their setup.

Now NC Miata owners can enjoy the same security with eccentric locks unique to their chassis, which is shared with the RX-8, so identical fitment there too!  The NC/RX-8 chassis uses two different sized eccentric bolts for alignment adjustment, so we're offering large and small versions, accordingly.  (There is actually a 3rd, larger adjustment bolt in front at the back of each lower control arm for caster, but it's not a threat to slip like the other 6 eccentric bolts)

You may purchase the large or small locks individually or as a complete set (4 large, 2 small) to fully equip a chassis (and get a discount!)   The large locks are used at the front of the front lower control arm, and the rear of the rear lower control arm.  The small locks are used at the front of the rear lower control arm.

This is a set of high quality shock spacers for lifting your NC Miata or RX-8! 

Mazda did an excellent job designing the suspension for the RX-8's/3rd gen Miata.  We designed these shock spacers to squeeze out every bit of suspension droop travel available without making major modifications or even changing shocks or springs.  Our spacers have staggered heights for max capability and proper rake.  Lift heights are 2.375 inches front and ~3" in the rear. 

Fabricated from steel with durable powder coating finish.  In general, you can use tires about 1-1.5" larger diameter than stock tire sizes without body modifications, but there are many variables so make sure you do plenty of measuring before you spend a ton wheels/tires.  Shown on our "Shop RX-8" are 225-60-17 all terrain tires and ~15mm offset steel Dorman Wheels factory replacement for Dodge Charger - (P/N 939-137)

The installation is fairly straightforward if you've worked on suspensions before, but you will need a full wheel alignment done on the car following the install.  Click here for the instructions:

NOTE: The pair of "Paco Moto" brackets shown is for the RX-8 chassis version of the kit only

These are genuine Mazda replacement eccentric (camber) bolts for your NC MX-5 Miata (2006-15) or RX-8 (2004-11).  The NC chassis uses two of the small bolts in the rear suspension, two of the large bolts in the rear suspension, and two large bolts in the front.   These are great to replace if your bolts are rusty or crusty, or they've been over-stretched with a bunch of torque in attempt to prevent slippage (our NC/ND Eccentric Locks will eliminate this).  Each Mazda Eccentric bolt comes with the matching factory nut.

LARGE - M14 - FRONT LOWER CONTROL ARM - FRONT POSITION & REAR SUSPENSION - 4 per car - BOLT: F151-28-66Z-- NUT: 9YB0-41-406A

SMALL - M12 - REAR SUSPENSION - 2 per car - BOLT: FE01-28-66Z -- NUT: 9YB0-41-208

NOTE: These nut and bolt sets come as pictured and do not include the Mazda eccentric washer - which gets replaced by our eccentric locks - if you're not using our eccentric locks you will need to reuse the eccentric washers from your car.
