3:73?? I have a 94 Z28 with bolt ons. (A4) I was wondering, if I get a 3:73 gear will I see a faster MPH in the 1/8 or quarter mile? I was thinking I'll be quicker off the line, but then run out of steam down the track...The car has the stock 3:23's on it now.
Also, what kind of tires should I get for the street that grip good. I have 275/40/17 SS rims on it now. I have the nitto drag radials on the car and they don't hook. Anyone know a good tire, because I know if I get a gear I'll even have worse of a problem...Thanks.

3.73's have a nice get up and go, and they are real good for 1/8 and 1/4 mile tracks. I have them and I still will get up to 150mph, so you will not run out of steam on a 1/4 mile. I have the same size tires on 17x9.5 Corvette Z06 rims, and I love them. The tires are BF GOODRICH G-FORCE KDWS, and they are real sticky. I had 3.23 gears, and the 3.73's are a whole different world, a nice edge on the streets.

What was your difference in MPH from the 3:23 to 3:73? Also, what was your E/T difference?
What kind of MPH change am I looking at. A 1 Mph gain, 2Mph gain?
Also, how is your highway driving? I think I would need another tune after the gear as well...
Also, how much harder is a 3:73 gear on our transmissions? I heard it cuts the life down.

I haven't ran on the track, but it is a big difference on the streets. It just makes things spin a little bit faster in the drive train. The computer will have to be re-tuned for the new gears.

I have a CAI, LT headers and the matching Y-pipe and an LT4 KM. I was thinking about a gear, but I don't want to have horrible gas mileage if they are not going to benefit me a whole lot. I hit an 8.4 in the 1/8 and that 60' still wasn't to great. I'm debating if I should even get them or not.
I was thinking that if I got a gear, by the end of the track I would hit O/D sooner, hence making my time a little slower. Same with the 1/8, I'll get into 3rd and it may slow the car down...

Unless you short shifting or have really small tires, you should be able to remain in 3rd through the 1/4
5700rpm with 285/40 r17s will get you to 118mph.

The weird thing is everybody says your supposed to gain mph with gears, yet when i went from 2.73 to 3.42 i lost about 2 mph while gaining .2 in the quarter. Not a recognizable hit in gas mileage, maybe 1 mpg.

well on the 1/4 what your looking for anyway is trap time or E/T rather then MPH yeah you need the MPH obviously but your E/T matters more then your MPH. in the 1/4 your E/T will vary by tires but the MPH will vary the most with how good the tires are so what your really looking for is a more consistent E/T rather then MPH.
