Title: diff question?? Post by: holdenhead on December 13, 2006, 01:59:46 PM Hi all,
Just wondering if there is a diff that would go in my FC that would get it cruising better on the freeway? It's totally stock but as I live in the outter suburbs of Melbourne anywhere I go It's Freeway or country roads. I just want to get the rev's down a bit. I dont mind just doing 80k's but when I'm driving on a road that has gravel edges and I have a line of cars behind me it gets a bit frustrating for everyone else as well as myself as I cant keep pulling off the side all the time. A diff centre would be best as I have just replaced all my brake bits. Any advice would be great. Cheers Rick Title: Re: diff question??

Agree with Greg, and note if you're running 70 series radials a taller diff will go some way toward rectifying the inaccurate speedo and over-revving problems. It's more or less a straight swap, although the later diffs have a different universal yoke. cheers RET Title: Re: diff question??

But if you're doing a lot of highway driving, there's much to recommend a change in diff ratio. And/or a look at tyre profile. It would amaze you the difference in rolling circumference between a standard 6.40 x 13 cross ply and a 70 series radial. cheers RET Title: Re: diff question??

I have 80 series radial whitewalls on it. They sould be right i'd think??
