Au Changing Diff Gears

Hi guys, My AU is currently running 3.08's Diff Gears and is a Non - LSD. Now i would love to Change ratio to 3.45's how much of an improvement would this give me. Like actual figures. I know take off would be heaps better but would it be constant wheel spin with Non - LSD. Will the seat of pants feel be alot better. I priced some gears and i think they were around $500 fitted for some second hand gears. and around $800 for new ones im not sure but it sounds a little pricey. I also priced lsd and i think that was about another $500 on top what shoud l i go ahead and do. I do hiyways km's alot and im only guessing another 200 - 250 rmp's will be the affect at 100km. Some info would be great

Definitly you'll gain a stronger off the mark acceleration. At 100km/h you would be doing about 2100rpm -2150rpm as opposed to 1850rpm.

As to wheel spin i don't think it would be too overwhelming. Infact for an auto falcon i would consider a 3.73:1 final drive.
