To do 4.30 gears or not to do 4.30 gears?

[Invader]

Just wondering what everyone thinks. Some of you may know that I'm in the middle of a rear end upgrade. And the time has come to choose the gear ratio...

i have them and love them... but 4.56s are coming soon

[Invader]

If I was going to do the 4.56 setup. I would do the 33 spline upgrade as well...

I drive my MM on road trips that involve state to state travel (1000+ miles) and being in Utah/west. there are a ton of roads with 80mph speed limits and I frequently cruise at 85-90, sometimes even 100mph. For me 4.10's are the max. Crusing over 3k its a little to aggressive for my tastes with a V8. I like that 75 is only 2500 and 80 is 2750. While RPM doesn't really hurt anything but you're obviously going to suffer big time on 80+mph road trips. Plus its extra RPM of wear and tear on accessories and the engine.

That being said. If my MM was a 100% city car that I used street/strip toy car and not my DD. It would have 4.30 or 4.56 in a heart beat. I had them in our 01' Cobra and loved the **** out of them. If you are a frequent cruiser at posted speed limits 4.30's should be great. City mileage may actually improve with being able to fall into OD at 35mph.

Nice to know. I really don't drive it much. And when I do it's usually in town... Oh, did I mention I work at a Shell Service Center. So I don't mind paying a lil extra at the pump.

Well if you want the best bang and most fun for when you do drive it go 4.56. I have 4.10s it was a step up but I'm sure 4.30s are way better from stock. If I were to go back and do gears I'm going 4.30 only because I do road trips. If it was an in town car id to 4.56 in an instant.

I like having an option to travel. You never know when #1114 might make a appearance at a Marauderville! :)

4:30.1 it is... Thanks for all the feedback guys.
Now my next question is to go with Hoosier or Motive???

My car has the 4.30's and they are awesome around town. IMO, if you do a lot of highway driving, I would consider them a little steep. IIRC, at 75 mph, the engine is singing along at like 2700 rpm or so. Luckily, I am not on the highway much. So, I don't remember exactly the tach reading. But 2700 seems about right. So, I just cruise at 65 or 70 and don't worry about getting any speeding tickets! :P :cool: :o Also, it seems that on my last trip on the highway (approx. 3/4 highway rest city driving), I avg'd almost 22 mpg:eek:. All city driving is between 17 and 19 depending on whether AC is always blasting or how much fun I am having...:burnout:
Hope this helps and good luck!

What size rear tire do you plan on using or have?

305/45/18 Nitto Drag Radials on 18X10 rims.

FWIW---I had 430's for a month--went on a trip to Fla and back and it was as side already a bit much for the highway and gas....around town I seem to never get thru the gears and again a bit too strong for my shift schedule--something you might want to look at for these----

I really believe and feel that the 410's are the best set up for all types of driving--which is what me and a bunch have---good luck with whatever you choose--

and BYW--those 305's can be used on a 9 &1/2 width rim as well---but on water/wet roads----watch out--not good at all---and several here have found out--those are for the drag strip only --IMOP---carry on

I'm doing a dual setup on the rear 305/45/18 0n 18X10 rim for around town and DD, and another pair of street radials for traveling and long hauls. But I haven't decided what size to go with yet, on the stock wheels 18X8.

Just the same--watch out went its wet on those 305's--be very careful and not much gas ,,,,,I went with 255's on my stock rims up front--a real nice fit and footprint---
