Nice to see something at a reasonable price too! Most stuff using the word Abarth at the moment is priced in the 100s and 1000s!

I would be interested in this part if its final drive ratio (not shown) does not increase revs in top gear. What is an ideal final drive ratio for a mildly tweaked 131R before i ask them assuming they can translate??

Thats a shame then.  Should i be interested in a lsd, i see a german co offers this service, what ratio is ideal for a normal road use 131R. Compared to a modern car my 131 feels like it could do with slightly higher gearing. Has anybody uprated theirs??

Rob,  I have in the past put a 10/41 axle in a 131 sport but thats two teeth lower geared but the effect is to give it a lot more pull in fifth as the engine is revving higher

Thanks David.   What would be the result if you were to put in a diff, say 2 teeth less. I was thinking of taller lower gears & quieter cruising from less revs??

What ratio does the sport have? If a Supermirafiori is a taller ratio then I have one for sale.

Doesn't 2 teeth less mean more strain on the rest of the teeth? i.e. less strength i.e. it will break easier?

Its back on original 10/39 now but it wasn't weaker on the 10/41 just a lot more fun. As I recall it was 300 -400 rpm more revs flat out in fifth gear but thats from memory.

does anybody know if diffs from 131 and 132/argenta might be the same?


Title: Re: 124/131 self lock differential for sale
Post by: mirafioriman on February 21, 2011, 06:46:46 PM
I don't know, but I would doubt it as 132 and Argenta axles seem to be stronger than 131 ones according to people's experience.
