Rear Arches

In order for me to fit the exhaust I needed to fit the rear arches first to establish where to fit the silencer and ensure the correct gap. I drilled two M6 holes in the rear of the arch and held in position and marked then drilled. Fixed in place with nylon M6 bolts, washers and nuts. These are quite strong and will snap if I knock the rear arch on track which will protect the body tub.

The arches fit with the flatter end to the rear and the angled end to the front.

To get the correct gap I measured the area around the tyre to be even, then I noticed that the ride height was with the suspension in the unsprung state and that it may be different under load. I then adjusted the ride height on the rear shockers to lower the car and then jacked up the rear wheel until the shockers were loaded. With this I positioned the arch and fixed in to place.
