That's a nice teaser Ron. I can't wait wait to see the aero all come together over the next six weeks.

Will the wing be a traditional bottom mount or a top mount.

Well Ron that pic still shows the deck spoiler but I will take that it is an undermount with uprights behind the rear bumper. :thumbsup:

There will be NO deck spoiler. The body illustration is just something I had in my arsenal to layover the chassis design. The body illustration shows several features (hood vents, no scoop, wheel flares, etc) that are not correct.

You've seen the body shell & where I had the factory kick up removed from the deck lid & flattened out for smoother air flow back there. It's all about the wing. :)

The dual element wing & mounts (upright & forward struts) in the blueprint are exactly how the wing mounts.

Ron,
I always wondered how much the ends effect the wing?
I see some with a lot above the wing and others with most
of the end below the wing... I guess if you look at the F1 cars
now they are adding louvers etc in the ends

I have changed the ends on my Pantera several times but
mostly for looks or holding a number

Hey Bob, good question.

The end plates on wings play a HUGE role in grip. The actually do two key things. First ... they ensure the airflow over the wing ... out near the ends ... doesn't simply roll over the sides. If the airflow did ... the downforce on the wing would be 20-25% less.

Second, the end plates create "side force". This is not talked about much in "car guy" circles. But side force is a big goal & part of the conversation in racing. Depending on the size of the end plates ... we can generate anywhere from 60# or 300# & more of side force at the rear of the car. This helps the car have more grip on corner entry, so we can drive the car in deeper, faster & brake later ... making us quicker of course. But sideforce doesn't add tire grip in the traditional sense like downforce does by loading the tires. Side force is creating a resistance to the back of the car coming around (getting loose).

Most of us understand g-forces from cornering speeds are pushing the car towards the outside of the corner. Side force is simply airflow pushing back ... on the wing sideplates. This gives us more rear grip ... but by reducing the g-force push with side force push back. This is why all racing sanctioning bodies that allow wings ... control the size of the end plates ... as much as the size of the wing itself.

More photos with update on the Track-Warrior roll cage structure ... and first glimpse of the backbone structure we use in our GT & TA Track-Warriors.

We now offer a tool we call the Scholl Fixture, named after Craig Scholl that gave us the idea when he created his own. In these photos, you can see how we use it to place the slant top boss that welds top the roll cage bars. This insures the boss, and the jack screw that threads into it, is parallel with the shock at ride height. The tool is adjustable in height for any shock height we use. The rubber donut on it is 3.5" OD ... the same as the OD of coil over springs ... so we can check for & maximize clearance before we weld it in. While we have these tools for sale in our Catalog HERE ... we "loan" these to our clients that buy Track-Warrior clips to insure they weld the adjustable shock mounts in true.

Such an awesome car!
Maybe I'll get to see it at Thunder Hill sometime.

Ron,
Just noticing in the pictures that the anchor points for the upper and
actually lower a-arms are slotted. There seems to be a labeled washer
or insert that you can move the a-arm anchoring points up or down in
the slot. I assume this is a piece that holds the anchoring bolt to a
certain height... are there different height inserts or are you just sliding
the anchor bolt up and down??

I ask this because someone else doing a second gen was moving his lower anchor points up or down based on info you gave him by welding a washer
in at a certain height... seems like the race cars with slotted anchor points
let you adjust this with the slot or inserts.. kinda of a trick thing if I am
thinking right

Bob
