i want to change gears on my car but i really dont know crap about it. i know i would be at higher rps on the freeway and stuff but with the six speed they arent that high up anyway.

does anyone else have these gears daily driving?

if you stay witha stock height (26") wheel and tire combination, i'd suggest not going any higher than 4.30's. if you drive around a 27 or a 28" tire. go for it.

I have 410s but my friend has 456s and his rpms were high as hell on the freeway (3k going freeway speed) but damn that car got off the line fast. My 410s are not bad at all on the freeway.

i turn 2k at 75 mph

its not to bad.
but you will be skipping gears a lot driving around the streets.

50mph in 5th gear = 2k just remember that. its not only about 6th. ALL yours gears are shorter, much shorter.

I'm interested in doing 4.56's as well. TTT...

2350 at 75 w/ 4.57s. Not that high, and you can actually use 6th gear other than just the freeway. If you race it at the track you will want some taller tires otherwise you won't make it through the 1/4.

I *love* 4.56 gears. To me, they're perfect. I daily drove my car with 4.56 gears (back before I built the new motor). Every gear was usable. No problems. I did it with both stock size and then slightly larger (26") tires.

And then when you go back and drive a car with 3.42's or 3.73's..... good Lord, those suck. Even 4.10's are nearly as bad. You find yourself with the gas pedal on the floor and saying "come on, RPM's, climb! climb! climb!".

Do it and don't look back.

Another thing to consider with higher (numeric) gears is learning how to really drive your car. If you do many power mods, you can't just floor it or tires will spin. I have 4.11's and with my mods wouldn't want anything higher while running street tires--which I do most of the time living in Seattle. Trying to go through the gears with nitrous is quite the challenge too. Consider your mods well before you decide which gears.

4.56 IS PERFECT. I can go 70mph and it barely turns over 2100 rpms with stock 17 inch ss wheels. I dont know were that guy who said it would turn high as hell got his information from. take it from someone with first hand knowledge. go with 4.56 and never look back!!!!

I wish I had gone with 4.56's! The 4.11's and detroit will be coming out and a spool with 4.56's will take it's place soon. 4.11's are good for a bolt on car, but if you are gonna stab in a big cam and rev it to 7k get 4.56's.

I have had the same questions about the 4.56's glad i found this thread. Just reading through it makes me want to go get a a new rear end with spool option and some 4.56's. Reason is because lately i have been looking at the Magic Stick and TREX as the cam of choice, just haven't decided yet.

So basically if i were to get the 4.56s i would just have to get used to RPMs climbing really, really fast. And have to go through my gears alot more, when i drive it whereever i go?

Basically yes... I have 4.30s and have to do the same. I end up driving around in 5th alot more than I use to.

So for me to choose between the 4.30s and 4.56s its all about my prefernce and what i can deal with?

i would go with the 4.56s.. ive got them in my 9 inch and on the highway im at 70mph pushing 2100 rpms and my friends 97 trans am with an automatic is at 2000rpms at 70mph with stock gearing lol so i dont think my 456s are bad at all

And how does it drive on the street, stop light to stop light etc. And when you go WOT on the street how insane is the acceleration?

well i have the fm15 cam and im used to driving it around town its not a hassle or anything but WOT on the street in 1st 2nd or 3rd doesnt accelerate too well lol but thats probably because its almost im possible for me to get traction.. but it does pull like a bat outta hell when i do get traction
