Red Bull

…gives you wings apparently.  In my case 1/2 of the Anzac day holiday gave me a wing…

This first pic is from inside the boot.  The wing needs something strong to push down onto – if you want to take full advantage of it.  So its mounted into the rear subframe, where all the suspension is mounted.  The idea is that every gram of down force that this thing produces gets fed straight to pushing the tyres onto the road – rather than the force going into flexing the rear body work.

And the other side.

Close up.  This shows the mounting plate where the alloy strut (see pics a bit lower down this post) mounts to the car.  It bolts on under here so that it can be removed if required – but it keeps the bolt heads etc out of the air flow.

Here are the alloy struts.  They go through the boot lid and attach to the mounts shown above.  I choose to do it this way to keep all of the mounts etc out of the air flow that is running over the car.

There is a single hole at the rear edge of the wing, where it can pivot.  The holes in the front edge allows the angle of the wing to be changed, meaning that I can create more or less downforce as required.  This change may be based on circuit characteristics or just to even out the balance of the car i.e if the back is sliding at speed, I can add more angle, and therefore more downforce to the rear to balance it out.

With the wing sitting in place, set about about half way through its range of adjustment.

A shot from further back, so better see the scale of the wing in proportion to the car.  I’m not sure if I haven’t gone too far rearwards with the wing to make it look right.  We will see when the wheels are back on and its out of the shed.

LOTS more to do before Wanneroo!  I did a list last night of the things remaining to be done – its a little scary…
