The wing stays are supplied in a set of 4. You will see from the picture below that the rear pairs are attached by drilling an 8mm hole in the rear upright for one bolt and the other is attached to the top calliper bolt with a bolt that is 6mm longer than the donor. You can drill with the suspension assembled. Just remove the shock absorber and use an electric drill from the inside, it is forged so fairly easy to drill. Alternatively remove the top wishbone bolt to allow access by pivoting the hub.

The front pair as shown below are attached to the 3 bolt holes that were intended for the tin dust guard, this involves pulling off the front hub bearing. Bolts to be 5mm longer than those removed.

The sketch below is taken from the IVA manual with regards to the requirement for positioning of the wings. You will need a spirit level to ensure that the wheel rim does not protrude beyond a vertical line from the edge of the wing.

We drill 2 holes for the wings stays to go into and then bond them to the underside with PU adhesive. If you are fitting the LED lights into your kick wings or G-type wings fit them before fitting wings to car.

It is important that thread lock paste is used on the calliper bolts and longer bolts/locking washers. The G type wing stays are designed to use up to 235mm tyres, see the Wheels section for more info.
