Nissan 370Z Forum - 4.08 gears and SRM

ok guys so ive been hearing lots and lots of different things about 4.08 gears and losing SRM. many threads on here about losing SRM wth 4.08 gears. question number one.: by "losing SRM" does it mean when u downshift it wont blip the throttle for u or rpms will be a bit off? question two: does it really affect it at speeds around 80 mph or is it just continuous redline shifts?two people just told me that it didnt affect SRM ever for them....unless this one guy he hit 140 and the light came on but im almost never gonna hit 140 and dont plan on it with roads around here.. question 3: which would win in a race from a 40 roll with the same mods....a stock ratio or 4.08? im asking bc since we lose mph if theres 4.08 the stock z could be at 3rd gear at 5500 rpm we'll be in 4th gear already...therefore giving them the advantage or more power in lower gear.....
