4.30 vs 4.56 gear
Im not sure.
I run on the street grudge race.
The speedo is the only non functional gauge in my car.....
I estimate on the HWY im doing 50 mph at 3-3,300 rpm.
My car is NOT fast (mph) but it is STUIPD QUICK. (ET)
i know im not helping much but i would definitely not worry about 4.56.
Im looking at a substantial increase in HP soon and i plan to reduce my rear gear by a lot. Hopefully i can keep my ET about the same but gain some more driveability.
