Alternate Diff Ratios for Fiat 850 based cars?

[Paul vander Heyden]

I have had seveal inquiries from people looking for alternate differential ratios.  The most common ratio 8/38 (4.88) is not to most people's liking when they increased horsepower output.

I would be interested in getting reaction what type of differential ratio might be desirable.  At first glance I would say either 8/35 (4.37) or 9/39 (4.33). 

I could have these made, similar to the 9/39 gears I had made for the Fiat 600 gearbox, but like anything else I am looking for confirmation of the need for such an item.  The miminum number of sets is 10, so it is a reasonable investment.  Retail price would be approx. $495.00 USD (350 Euro).

I look forward to your comments.

Hi Paul, maybe you should post this on the Fiat 850 Yahoo Groups email newsgroup?  Also, perhaps mirafiori.com?

  I'll repost the text from Paul's thread here to those other forums, as I think the "message" got a bit garbled within our drivel. ;)
