Matthew,I say stick with the 3.91,s for now.Once you take your car out,you might change your mind?With 4.57,s you,ll be limited,yes you,ll get the ricer off the line in town,but i think your gonna want more.My opinion!(higher revving=more gas)
hey scott, the reason i want 4.56 is because i have overdrive...so that way i can have the best of both worlds...nice acceleration to eat the ricers and nice highway cruising (with 4.56 gears and the tire i plan to run i will be turning 60mph at 2200 rpm which is awesome!8))...so im not too concerned with mileage anymore...anyone with 4.56's please message me!:-D
