My Caterham’s nosecone will also be wrapped in PPF (paint protection film, like the rear wings, so I wanted to get the nosecone to fit properly before the PPF is applied. The important part of this exercise is to check the clearance between the nosecone and the suspension components. If the nosecone touches the anti roll bar or lower wishbone, then that is an IVA fail. That said, the IVA testers I have meet would have given you some time to adjust this sort of thing on the day, so be prepared for that.

But since I know what is expected, I might as well sort the fitting now. I started with ARB. The right-hand side had plenty of clearance, the left-hand side was another story. Time for the Dremel again.

I took a slow, step by step, approach to this; the nosecone is an expensive part and I didn’t want to cut too much away, and the Dremel can do that all to quickly if you let it.

I turned my attention to the lower wishbone fitment, and this time the left-hand-side had plenty of clearance, but the right-hand side was less convincing.

In this case I didn’t go mad, just enough to make the clearance as required. The ride height is very low at the moment, so that gap will increase the ride height is set correctly.

One final observation I made was the 7 grill is actually touching the cooling fan motor. I raised this with Caterham and they advised this is normal. I believe this is only a problem if you specify a painted 7 grill, because a combined 7 and mesh grill is fitted when this option is not selected. For now my plan will be to apply a small amount of self-adhesive rubber on the back of the 7 grill, where it touches the fan motor. Long-term I may switch to the combined mesh&7 grill and endure the painstaking task of masking the 7 from the mesh and painting it. Ultimately a painted combined grill has a bigger visual impact than the 7 obscured behind the mesh.
