Well I finally installed my gears. They were FRPP 4.30s. Did the install with a buddy of mine from the forums, and it actually wasnt hard at all. It was more tedious and all. From driving the car so far I can feel a difference but I obviously haven't jumped on it yet. There is a very slight whine when decelerating, but you really have to listen for it.

Wow...4.30's? I take you don't drive on the highway too much lol.

the RPM's are not that bad. 75 is at 2600, only 100 more than 4.10's. But I am not on the highway much at all. 95% of the roads I'm on have a 55 mph speed limit or lower.

Okay, i would've thought the rpm's would be higher than that. That's pretty cool then!

Congrats! You need to get on it and see how you like them.

EXACTLY everyone acts like there is a huge difference between gears.. its really not that much at all.

I wish I went 4.30s instead of 4.10s.

You really paid $280ish for FRPP 4.30's when you probably could have gotten them from Motive or something for closer to $230??? I mean i got FRPP 4.10's for $130. What finish were your gears??? Because my 4.10's were like polished and they did not install like typical FRPP gears and they whine a slight bit like you said on the decel. I think FRPP are making sucky gears now. The pinion gear just slid onto the bearing...that is supposed to be pressed on and they didnt come with a pinion nut which my mechanic said that they always used to come with. So i think that FRPP is starting to skimp out on their stuff.

P.s. ^^^AGREED 10000000% but im switching back to 3.73's when i do my rear end to prepare for boost. :/ so wont be as fun without the boost but once the turbo is in...it'll be just fine

I had 410's in my Mach and changed them out to 373's that lasted about 3 months and i went with 390's because i was commutting 84 miles round trip to work or 1,980 mile a month just for work.

LOL the difference from 373 to 390 to 410 is maybe 1mpg.. for each step up

I should have just kept the 410's so now i also will be getting 430's since i only use the car to commute 6 days a month now.The argument of going with 410's over the 430's if you drive on the highway is an invalid argument since the gas milage will not even be noticeable,although a 2v car is different.
