Is there a quality difference? Does one whine? I know Motive Gear is about $50 less, so is there any reason not to go with them? And do I need to get a new master bearing with 20,000 miles.

Definately FRPP. I have heard of tons of people who have a whine with the Motives. Virtually none with the Ford part. Not sure about the bearing though but it wouldn't hurt.

I figured you get what you pay for. Thanks alot.

Without a doubt +1. Just do a search on any mustangs forum website and you will find dozens of threads about the motives being bad. FRRP is the only way to go for gears.

I thought that was what everyone has been saying over the past year, but I made the mistake of reading one of Motives ads, and according to them they make less whine than any other gear and are the strongest too. So I'm glad I asked again on here just to straighten that up. [sm=closed.gif]

Does FRPP make a 3.90? Also anyone know anything about Microniting?

No I don't think FRPP makes a 3.90 gear.. I could be wrong but don't think so..

sorry don't know about Microniting..

as I only had a choice of 3.73 or 4.10 gears.. so I went with the 3.73 as final gear.

( 4.10 was to much for me.. to much highway driving )

the only reason gears whine is if they are installed incorrectly. period, end of story, and if its a manual i would seriously look at getting 4.30s with the t3650 tranny, you will be at 2800 rpms at 80 mph and loose liek 3 mpg

[sm=bs.gif]BS - Some of the top installers in the country get whine with the motives. So you're saying Jim & Jim Jr. at JDM, Mike at livernois, Justin at JPC, Adam at ST Motorsports, Mike at powerhouse, derrek at D'agostino, chuck at che DON'T KNOW HOW TO INSTALL GEARS? Cause all of these guys will tell you the motives are bad. Your experience is NOT on S197's and I hate to break it to you but they are just a little bit different than your cars.

FYI I'm at 2900 rpms with 4.10's @ 80 mph. You would likely see 3000 rpm @ 80 with 4.30's.

How much street performance do you even get with 4.10's. On street tires, won't I just be spinning all over the place. It seems like for street races on stock tires, the 4.10 could hurt my performance. Or is it just something you have to get good at. Or can be corrected with better suspension?
