Repzard, what RPM are you shifting at??? Our cars dont pull very hard after 5200rpm. So i suggest you shift right around there if not a little bit after and it will keep you in your powerband. And if your car still doesnt pull...there is something wrong with it. Anyone around here will tell you that 4.10's are a great gear and you will be sorry for going back almost to stock gears. You should be trapping in the low 100mph range and in 4th gear and plenty of people are still pulling at that point. So you might wanna check into your car a little bit more if its not pulling very hard past the 1/8th.

i've got 3.73s in my car and they're a real good fit, but then again i'm pushing near double amount of power as a stock 4.6. when i was still n/a i wished i had gone with 4.10s, but now with the blower the 3.73s are just right.

I forget but what is the recomended break in period for gears? I've heard a few such as a few 10 minute rides

There is no break in period for FRPP gears. At all. At most the installer will run it a few thousand feet to make sure they dont make noise(to insure proper installation of shimming), then its anything goes, romp on it.

Recommended break-in period for any gears is 2 heat cycles. You should take your car out for a nice decent drive and let the rear heat up to running temp. Park it and let it cool back down. And then repeat. Thats what ive been told and i would never ever run something hard right from installation. Thats just begging for trouble in my book.

I'm sorry, but you are wrong. First of all, gears are heat treated when they are manufactured, so they do not require being heat treated after they are installed.

Secondly, the amount of heat generated in your rearend would NEVER be high enough to heat treat or harden gears. Steel needs to reach in excess of 2000 degrees to even come close to being hot enough to heat treat.


So what is your theory behind the "two heat cycles" thing?

And as far as not beating on things right after installation, I can't think of a good example of a component that would require a break in period, anyone else have any thoughts?

That *** is so hot.

Thanks, I haven't really started looking yet. I'm just enjoying the summer lol.. Hopefully I'll have some luck in finding a decent job, if not I'll continue with school.

And an auto with 4.10s is AWESOME!! I'd highly recommend 4.10s with a tuner! I know I'd be disappointed with 3.73s, the 4.10s seem perfect.

Thanks! I thought about the wingless look or the Cobra spoiler as well but ended up with a Saleen spoiler. I like the swept back look, reminiscent of a drag spoiler in a sense. I'd probably be just as happy wingless though lol

Ok cool, I'll definitely look into a TB/Plenum for my next mod. I'm not looking for insane power right now, just a fun all around DD.

My degree is an Associates in Business Administration with a focus in Operations Management. I also received two certificates, one in Logistics Management, and one in Total Quality Management... I mainly went into Bus. Admin. because I didn't know what I wanted to do as a career. With that degree it can almost be applied to any job/position.

I was told to be easy on it driving it home, then romp the shiz out of it the next day on. So I did just that lol... The gears feel factory installed, absolutely no gear whine or anything.

You can look but not touch, she's mine lmao
