Replace your angled thermostat outlet with this straight outlet for more clearance near the downpipe.

All three fuel rail ports are tapped for 8AN ORB.

Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

Manufactured with a large 0.69" internal bore, the fuel rail can support all necessary engine power requirements.. The rail is CNC machined from solid 6061 aluminum and bright-dip anodized for a high quality surface finish. It is compatible with all fuel types including popular alcohol mixtures such as E85.

This comes with both of the below items, making it install directly to the stock Evo X Fuel System.

The Girodisc system is a direct replacement iron rotor for the OEM PCCB disc, no modifications are necessary. The disc will bolt directly to the car and work with OEM calipers and pads perfectly. 

The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum.  The disc is made from our own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc.  The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.

The rotor and hat have a floating mount system, which utilizes 12 high strength alloy steel drive pins, manufactured by Girodisc in the USA to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by class 12.9 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.

Once the Girodisc system is in place, simply replace the cast iron rotor when needed.

The Girodisc system is a direct replacement for the OE disc however you must use the same pad shape that is used on the 991 GT3 that came with the iron rotors from the factory.  The annulus (pad swept height) of these pads is smaller than the large PCCB pads, this is done to keep the rotor weight at a reasonable level and allow far better pad selection.  If we manufactured a rotor with the same annulus as the OEM PCCB rotors they would be unnecessarily heavy.

Looking for that secret edge? Flyin' Miata's billet aluminum sway bar brackets are lighter and stiffer than the ones that come with our bars. Plus they're less likely to end up with the bolts pressed up against the edge of the bracket - if that's happened to you, you know what we're talking about. No more messing around with inexpensive bent steel brackets, these drop right in to place with a nice flat surface to mate up to the mount. Anodized matte black.

The opening is 39 mm (1.535") wide and 48 mm (1.890") tall at the tallest point. Fits the oversize bushings used on front FM sway bars. Includes new hardware.
