Caterham ring and pinion

[MichaelD]

Does anyone know what the ring & pinion used in a 1998 DeDion came out of?

 

I may want to move to a 411 from a 396.

 

Thanks,

[Ian7]

thats a lot of work and $$$ for at best 300 revs.

Whats the other advantage?

Michael,

 

Ford Sierra 7".

The highest numerical ratio from Ford is 3.92 There are aftermarket 4.11 CWP sets available. Can't recall offhand who does them.

 

Here's a good guide to the Ford Sierra diff and code plates.

If you find a 4.11 CWP, here's the manual to do the swap.
