I have FRPP 4.10 now. however, i want to have 4.30gear.
anybody have feedback?
i want to know what rpm will be on 60mph?
there is not much enough info for 4.30gear.
Ford has M4209-G430M for 4.3 and it seems motive gear.
Is it OK with my car?
I do not care about top speed and MPG.
Any other negotive things?

you will need a higher revving motor if you do that. your max rev with those gears should be around 8000 imo. but do what you do if you really want.

why do you want that gear?

You won't feel such a small increase. If you want more gear, go 4.56. 4.10 is perfectly streetable and not aggressive in my opinion....4.56 is a different story, although I have had 4.56s on the street and I think it's fine. (this was not in my Mustang though)

If I didn't plan to supercharge one day, I would have definitely dropped 4.56s in the Mustang.

I drive mine once a week or less. i think 4.10 is really good for DD, but i want to have more power at low speed(0 to 60mph).
I also think about 4.56s and i do not have plan to have turbo.
How was it on 60 mph with 4.53s?
i have another car for top speed so i do not care after over 100 mph.

Thanks.

It was fine at 60 MPH. You could definitely feel it being wound up at about 60...I don't remember the RPMs of anything but it wasn't like it wasn't streetable. If you're looking for power under 60 MPH it's fine...if you're looking for speeds above that for extended periods of time, I'd stick with the 4.10s.

You should call Brenspeed and see what they suggest for you.
