Am I right in thinking the French Spi automatics had a final drive ratio of 2.76?
What are these like in the real world, and is possible to convert a UK automatic?
Many thanks
Johnny

Many thanks Johnny All Mini 1275 auto's had the 2.76:1 final drive.... all final drives are interchangeable as a matched gear pair but you will also need the speedo drive gear set as well as needing to recalibrate your speedo. |

What final drives were available for the 998? I've seen my 81 998 listed as 3.27. But the same place also said 3.17 for a 1275 unit.

I thought my car had a final drive ratio of about 3.27. She's doing 4000rpm at 70mph and I think with a 2.76fdr she should do less than 3000rpm at 70mph. WKR Johnny |

Never seen a 3.17:1 ? maybe a mistake, as far as I know, there have only ever been 3.48, 3.27 and 2.76 ...
