Ryan Passey’s Amazing Miata


Data logging is handled by a Racepack USM Sensor module shown here which communicates to a Racepack IQ3S display via a CANBUS.

A high mounted Moroso expansion tank is recirculated and removes air bubbles from the cooling system.

The front of the chassis has been cut away forward of the shock towers to the limit of GTA rules.  The unibody in this area has been replaced with a tubular modular subsection that holds the radiator and oil heat exchangers.

This front module can be removed for repair in minutes with the help of Radium dry break quick disconnects for the fluid lines. This also makes it very easy to remove the engine.

Sealed ducting directs air from the front bumper through the forward canted aluminum Goodwin Racing/CSF triple pass radiator that was originally intended to fit an NC Miata and up out of the lovered hood instead of backing up in the engine compartment.

These tubes brace the shock towers and couple to the roll cage. They are equipped with machined sections that are bolted together to allow for their quick disassembly to speed engine removal and servicing if it were to become necessary. The shock towers are reinforced for stiffness and the entire chassis is seam welded, also to increase stiffness.

The car uses a Wilwood 1″ tandem master cylinder in the stock location and OEM clutch hydraulics. No pedal boxes here.
