Record Breaking: PZ Tuning’s 531 WHP RSX!


The final piece of this puzzle is the aero. Just as we have seen throughout this build, Will and PZ Tuning have their special touch everythere. The Mugen wing at the rear of the RSX is probably the only off of the shelf piece present. And that has been the benefactor of the custom Shark Fin that Will added as a vertical stabilizer, enhancing rear stability as speed increases. When I captured some pictures in late October the front splitter and canards were very functional, but I remember thinking to myself that the plywood splitter did not quite fit with the rest of the aero features.  I was back the day the RSX was loaded on the trailer because in less than a week the splitter and canards had been completely revised. The plywood was relegated to back-up status and an alupanel splitter and aluminum canards were now in place. The canards’ side pieces tie into the splitter, giving additional strength but also keeping the airflow in where it is wanted. Both corners of the alupanel splitter have aluminum runners bolted on that span the depth of the splitter to provide ‘grinding’ room should the splitter contact the track. The underbody treatment is also made from alupanel and an 8’ by 6’ sheet has basically been fitted under the car. The panel extends to the width of the rear tires. Then it ties into the custom PZ Tuning rear diffuser. There is nothing to say except that this really looks cool! The car, in black and silver, is a beautiful piece of machinery.


The Alupanel flatbody treatment is notched to allow room for the oval exhaust Will fabricated from Vibrant Performance pieces. The underbody tray then ties into the custom built diffuser.
The underbody tray extends out the side of the car to the width of the rear tires.
Less than a week before heading to California, Will completely redesigned his front splitter and the canards. The plywood was replaced with Alupanel. There's an 1/8″ aluminum runner bolted to both sides of the splitter, to provide some 'grinding' material should the splitter come in contact with the track.
The canards now have a side plate that ties into the splitter. This not only provides added strength for the splitter, but keeps the wind in place to ensure that as much downforce as possible is held in place.
Plus, it looks really cool! As you look to the rear right of the splitter/canard you can see that the plate flares out. That's to direct the air flow away. You also get a great view of the ducting to cool the brakes plus the intercooler.
