Caterham Differential Struts

[scannon]

When Gert and I visited Caterham USA last week Jon showed me the differential strut braces that go between the upper rear bolts on the diff cover and the underside of the upper transverse frame tube that has the bosses for the shoulder harnesses. It bolts into the bottom of the harness bosses.

 

Since day one with this car I have been concerned about the effects of the torque of the turbo motor on the diff mounts. I looked into fabbing a set but never got around to it. When I saw these I bought a set.

 

Installation of the struts is easy, what is not so easy and yet to be accomplished is cutting the holes for them to pass through the floor of the boot. I'll post more pictures when the floor is finished.

Ben told me to start with a small pilot hole in what i thought was the right place. Then run a string between the mounting points and see which direction to enlarge the hole.

I attempted the string method. Holes still ended up getting a little larger than I had hoped for. I ended up dividing the forward boot floor into two pieces to get it in place.

 

In retrospect, I think I'd opt for a cardboard boot floor pattern If I had it to do over.

 

One thing you'll notice about the diff struts is that the side curtains will no longer be able to be stowed in the boot. At least on an S-3 chassis.
