Stock rear gear ratio?
Trying to find out my stock gear ratio, For some reason i thought they all came with 308s then i read about some 273, no tag on door, can i tell from VIN? Im kind of thinkin might have 273 because I can drive like 160km/hr (100mph) at like 2000 rpm approx and cruisin on highway at 100km/hr i almost have to be in forth gear, hit 5th gear around 120 km/hr. Anyways of thinkin if i de in fact have 273s i think my first mod should be a gear change!!

they came with either 2.73,3.08 or 3.27s there should be a tag on the diff that will say for example 2L73 for a 2.73 with limited slip and so on.

4th gear 2000 rpm is 90 km/hr, which is 56.25 m/hr so i guess 273s? so 373s should be one hell of an improvment
