Hugo, in real oem you find the numbers, and the model of car, when i have my old Ti y prove some diff, in my Ti i use a M3 Manual tranny so i finish with the 2.93lsd, but before i use 3.73 and 4.10!!!!Never find the 3.46 or 3.45 in Puerto Rico, i think if your Ti is Supercharger you need the 2.93 or somekind of 3.2??? if th Ti is NOT supercharger the 3.73 is the perfect number for drag __________________ BMW...MY NEW TOY Mods: Some plastic parts, ///M Wheels and me |
