Suitable VX diff ratio?

[MrSirWantalot]

Hi guys, after some thoughts on what diff ratio to put in when I rebuild diff. Berlina sedan with LS1 is mafless has 315kw....so not standard. It currently has a 3.46 ratio lsd out of a VY Maloo but is on way out!. 3.46 is good off the line but I just wonder if there is one more suitable etc 3.7, 3.9?. Top speed is not required but I would like to keep the quick take off....Anyone with any thoughts on the most suitable ratio??

3.73 for an auto and 3.9 for manual. I put in 3.73 in my auto vxss and if you want fast take off, thats what
you will get. Totally different car to drive from factory diff ratio.
3.9 will see ya revs up too high for highway cruising, so 3.7's are a good choice. Buy genuine gears
though as aftermarkets are cheaper but they can whine and will drive u crazy!!!

3.9 would be awesome on a manual

you could actually used 6th gear!
