MotaLeira today's progress

Just tacked these up this morning.
They are not fully welded and have no trangular plates on yet. I also plan putting a rod across the widest point, once they are fitted to the pick up points on the rear subframe. The second photo shows the A1GP car setup, that I saw at Goodwood on Friday, to show what I mean about a rod across the bones.

It is a wheel tether.
Inside the aerofoil profile is a steel wire to stop the wheel flying off in an accident.

Isn't the bar in front of the wishbone the steering rod?

In the GP cars that rod is only there to stop the wishbones from puncturing the tub in the event of a crash as the drivers legs are inside there, it's not a brace to add stiffness or anything. This was explained at the NEC show by one of the exhibitors.

Maybe so on short span wishbones, but on my car they are very wide and I prefer a bit more strength. I just used this picture to illustrate how I would be adding the bar to my bones.

Take a look at the top right end of the wishbone. There is a rod end and in front of that, the tether. This has a small shield taped over it.
