Witte 05

I was thinking of putting a Ford Racing set of 3.73s on my 05 GT...anybody have any thoughts on this... I thought it would be a nice happy medium...and where is a good place to get them...I saw them on Jegs for $171.00...Also planning a SCT Tune with CAI from Brenspeed, right now Its stock besides Flowmaster Axle Backs and hurst shifter....

Honestly I would go with 4.10's. It's not that much of a difference for fuel economy and it'll pick up so much better.

Also I like ordering from Americanmuscle mainly because there is no shipping cost and they are cheap. That and I have never had a problem with them.

Since its an 05 it should have 3.55 gears. I would recommend the 4.10s.

motive, who apparently makes the frpp gears, makes some 3.90's. i am in the midle of buying a set of them right now. to me the 3.90's sound like the happy medium.

Thanks for the info... I was a little worried about going the 4.10 route because my car gets driven daily...but the 3.90s sound pretty sweet

I have 4.11's, and it is sooooo much better than 4.10's. Anyone who has 4.10's instead of 4.11's is a loser!

I have the 4.10s and highly recommend (assuming you are 5spd). I guess it may depend on what you use the car for but I don't see any downside to them. If 90% of your driving was on the highway then maybe go with a looser ratio but otherwise...they kick butt around town and on the twistys. The combination of 4.10s and a CAI with good tune make it pretty special. I can spin thetires at will in 1st, not just from a start, and that's with some pretty sticky rubber on the back. Are you going to do the install yourself? If not...the total will cost you between 500-600 depending on shop who does them. That includes FRPP gears, install kit, labor and fluids. Brenspeed will do you right on the CAI and tune.

I drive about 70 miles a day and thaey're fine.

The way things are going right now , I would think, , going to 3.73 Gears, , would be agood choice , as compared to say 4.10 , or 4.30 Gears.But that's just my opinion .

I luv my 4.10's I luv em.
If not 4.10's, then go to 3.90's imo
