With the backing plate in place, we bolted the base plates for the wing mounts to the top side of the trunk lid. These are bolted through the trunk lid and backing plate with 3 bolts and some super sticky 3M adhesive tape. There’s also a foam strip around the bottom side of the base plates that allow them to make a water tight seal. All in all, these are very nicely designed pieces.
Next we bolted up the swan neck wing mounts, which have multiple mounting holes at their base as well as where they mate up with the wing element. This gives the wing an extra level of adjustability, since it allows you to move the wing’s position forward or backward (the further back you mount a wing, the more leverage it has on the chassis and thus the greater its ability to produce rear downforce).
There is, of course, provisions to adjust the wing’s angle of attack via a series of bolt holes on the wing mount attachment points on the top side of the airfoil itself. We set the wing to a fairly mild angle of attack for now, but will do some testing at the track to see what wing angle gives us the best overall aerodynamic balance when combined with a front splitter we’ll be fabricating with the help of our buddy Kevin from C3 Composites. For more information on how we’ll be building the FR-S’s splitter, check out our multi part series on the carbon splitter we built with Kevin for the ASS2000.
With the wing mounted, we decided to bolt up our fresh new rolling stock for the FR-S this year, a stunning set 18×9.5 +40 Advan Racing GT wheels in Racing Titanium Blue and a fresh set of 255/35R18 Toyo Proxes R1R extreme performance summer tires.
These are the new 200 UTQG R1R’s, which makes them legal for Street class autocross and time attack competition as well as Ontario-1500, which has a UTQG tread wear requirement of 140 or higher. We will be doing a full track test of the R1R’s very soon, including all sorts of data on cornering g-forces and speeds, so standby for that.
As for the wheels, to be honest I wasn’t completely sold on the idea of dark blue wheels on our Asphalt Gray FR-S, but once we rolled the car out into the sunlight, we were both totally blown away by how badass they look, especially in combination with the Voltex wing. The look of the car is utterly transformed, and we’ve only just started. Once we get our new livery on there along with a few other aero upgrades, it’s going to be full on Time Attack craziness.
Next up we’ve got an engine swap to knock out, but in the meantime enjoy Episode 2 of our Ontario-1500 build series and let us know what you think of the mods so far!
