I have been contemplating a 3:55 to 4:10 swap for awhile but am looking for opinions. I did a search and many seem to think its too much for 1st gear traction on a street car and not advisable for the track without going to a taller tire (car will never see track duty). I plan to use a 325/30/19 Toyo R888 (26.7" high vs 26.9 stock) and I am not really concerned about 1st gear traction as most "differences in opinion" on the street do not occur from a dig in my experience. My car is also not a DD so day to day driveability is not a concern either and I've always felt the car was geared a little tall for cruising within the constraints of the speed limit too. Will a 4:10 swap give me a noticeable change in acceleration through 2-6th or will the difference be negligible and be best to stay with the 3.55s. I suspect I am in the 650rwhp range, mods are in sig.

Ive got 3.73's from the factory with stock Spinyears. Unless my goodyears are HOT, I can still get the rears to spin at the top of a hard acceleration in 2nd. 4.10's would be a fantastic option if you were running at the strip with full on drag radials.
For the street id stick with 3.73s

Stick with what you have for the street, I have 3.55s as well.
Do you end up still on 4th gear on a 15 tire 28 height?
4.10 + 2.96 1st gear = Bad combo
I think most guys go with 3:73's, as 4:11's are just way too short.
I would check out the gear charts and buy according to your driving habits. 1st is a lost cause no matter what, so no traction is no traction. However when your doing 60-65 and you need to resolve an issue with 3:55s it is scary as hell to consider second gear and 3rd gear seems to be a bit to low in the power band.
So I would shoot for a gear that puts you at the 4k rpm range when doing 60-65. If that's your goal.
As much as I hate adding to traction problems it seems like you get screwed both ways with 3:55's. Mine is a DD as well so I know exactly what your experiencing.

i have 4.10's and you really need a 29" tall tire to even make it an option.... otherwise its just to much.... wich honestly is very fun to drive at least for me.... but would be a hanful on that toyo. I have been driving around (weekends only) on 29" hoosier slicks recently and they will still spin in second a bit(~750rwhp). 4.10's and street tires just will not work in theese cars with a 26-27" tall tire and 650+rwhp in my opinion
Holy crap, you still spin with DRAG SLICKS.... lol thats awesome
