sotp difference from 3.90s to 3.55s

i was considering stepping down to a 3.55 gearset. I want to rap out gears longer and my first gear is useless and i was some fun on the street.
also how much slower do u think it would make me at the track??

hey what mph can u take 1st and 2nd to???
and whats the rpms at 65?

On a 26" tire the 3.90 will be better for your car at the track. Should have you hitting the traps at a better RPM.

I went from 3.55 to 3.90 and gained 1-1.5 mph. It lowerd my ET as well, dont remeber how much. Want to say close to .2.

if you get 3.55's pm if you want to sell the 3.90s im interested in getting a set.

to be honest with you, im sorta easy on my stuff and havent really paid attention the mph on the 1 - 2 shift. but i can this evening when i drive it.
i can tell you 1st gear is definetly not worthless.

@ 65 in 5th im runnin maybe 1800 - 1900

I have 3.55's It depends on the 5 spd you have, some have different 1st gear ratios's, With the 3.55's my first gear is almost worthless I only stay it it for a few seconds. It sounds like you have a trans with the 2.95 or 3 something first gear. I drive mine on the street mostly a weekend car, but I do hit the freeways, I wouldnt want any more gear than I have.

i have the 2.95 gearset.... it helped a bit with first. but i took a ride in a buds car with 3.55s and i duno what it was, but i just loved how it felt. Still gave u the sotp but the gears lasted longer and just overall felt nice.
