I just wish i knew how tall in inches my tires/wheels were. Because 4.10s look good but on a taller tire, i think 4.30s would be great for a track focused car. 4.30s shift points were, 35, 60, 91, 120.

But my question lies in, what if you had enough HP with 4.30s to trap higher then 120, then youd have to shift into 5th before the traps? Or get a taller tire and how much does a taller tire help?

I just never saw the point of people not liking gears. Im in NY most speed limits are 55 or NJ 65 is the most i see. with 4.56s at 70mph your at 2500, at 65mph its 2,400, 60mph its 2,200 and 55mph your back to 2k rpms. I know everyone doesnt go the speed limit. Im not saying i do or most the NY driver son the thruway. But its nothing soo insane that makes the car unstreetable because of how low our overdrive is. A lesser gear like 4.10s would be even less. So to sum it all up, I give thumbs up to gears. Untill im heavly boosted ill be behind at least 4.10s, after boost ill try 3.90s and lower.

usually get a taller tire. however, by the time machs make power to trap higher than 120, they'll have a healthy power adder, and whoever did that decision probably didn't go with 4.30s or plans on putting lower gears on it... guess it depends just how far above 120 they are. shifting into 5th would most likely kill your time and make you drop below 120 :p

as for the 4.30s being for a track focused car, i disagree. mine's a daily driver, and it'll be a while till I max out these gears with 120 mph traps...
