BMW Diff

[Guest Terry]

Is anybody running the new BMW diff in their Caterham? I am trying to find out what Bmer this comes out of.

I was told by Jon Nelson it was from a 1 series Bimmer. Not otherwise verified this myself.

Thanks.

I was at Caterham USA yesterday and Jon told me the same thing. They use a sort of cage around the diff and it bolts to the same mounts as the Sierra diff. As usual, I forgot to take along a camera to get pictures of it.

 

While I was there I saw the struts they use to provide additional strength for the diff. They mount to the bottom of the inner shoulder harness boss and go down to the back of the diff. Jon said the hardest part of mounting them is cutting the holes in the boot deck they go through. I bought a set as my biggest worry is the strength of the diff mounts vs. my torquey turbo motor.

 

Jon said that they are expecting their first Sigma engined Caterham in the next shipment. It will become the entry level Caterham in the line up here in the USA.

 

Sales are brisk, every car in the last and the next shipment is already sold. He is having problems getting the cars assembled quickly enough. I got the impression that most sales are completed cars rather than kits for the owner to assemble.
