Any body with an automatic car running 4.10's with the TCI superstreet fighter? I'm getting the converter soon, and was also planning on sticking 3.73's in my car, but since i have a set of both, I was wondering which on to go with. What rpms are you guys running with the 4.10's and 3.73s at 60? Anything else helps. THis is a daily driver, i don;t care about gas mileage though. Put about 100 miles a week on it.

I think 4.10's with an A4 is overkill for street use. I would go with the 3.73's.

I would go with the 373 unless you are on slicks all the time. I have close to the same set-up as you and have 342 gears and very happy.

not that i ever need to top out my car, but what will the 4.10's limit the car to? still about 130?

About 124 in third gear with 26" tires. If you ever need more mph, can always bolt a bigger tire on.

If your talking top end all out, its in excess of 160 im sure.

4.10's are too much gear unless it is mainly for the track.

I disagree. I love mine.

same here, another happy A4 driver with 4.10's. as far as the rpms at 60.. i'm not really sure but it's not too bad considering i turn 3000 at 80 mph. i wish i coudl tell top speed too but when i ran a viper about a year ago i wasnt looking i was at 140 last i looked at teh speedo.
