diff ratio change

[jonboy]

hi
im looking into changing my my diff ratio to 3.45.
iv got the getrag 5 speed behind ecotec, its a vs sedan, solid axle
can anyone who has done this change let me know if its worth wile?? or it dosnt really make much differance?
also im thinking of just keeping it a single spinner or is this just madnes?
can i fit lsd to the new diff gears at a later date? (if i found some cheap)
any feedback much appreciated
cheers

iv had it done to mine,, as for ratio it really depends on the sort of driving you do,,
i have a new set of 3.45 gears sitting here that are currently for sale, they are good for manual cars because they aren to tall,,

yea im in new zealand so ill probly look locally thanks.
so 3.45 is a good ratio for a 5 speed? economy and revs shouldnt be afeccted to much should it?
my car at the drags did a 16.5. could i break 15 with this ratio?
cheers
