Id go for a 3.25lsd rather than a 3.15. I have a 2.5L non-vanos with 4.10lsd and it gets the same mileage as my old 3.25LSD on the highway and it revs at about 5k @75-80mph. I also have proof from a trip i took to New Hampshire, well over 40 hours of driving alone at that RPM and gas mileage was about 28-30mpg.
As far as an auto equipped ti goes, 4.10lsd is about as high as id go, for a manual, the 3.45 is the best but would prefer a 3.73 over that. __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone
