Default 6 speed guys, tire growth, and RPM thru traps

What tires are you running, what gears, and what rpm are you seeing thru the traps (hopefully not indicated by the stock tach )

Looking for info on 4.30 and 4.56 geared cars preferably 118-128 mph cars

by that Brian says you should be good for 122, so I guess growth accounts for that extra 3. That what about a 3/4 inch growth, that seem reasonable?
