Motive sells all the gears at a reasonably price. They also sell 3.90 which seems like a good idea

FRPP>MotiveHatchman said:I think 3.93 would be a nice compromise, and I've heard the Motive gears are a little better than the Ford gears. One guy in a thread was having reliability problems with the Ford 4.10's (they broke on him).
I haven't tried either yet, just what I've heard.

Since Redline is 6000 RPM the 4.10 gears may actually allow the Mustang GT to overcome some of that drag and pull a little further up the RPM scale towards the 6000 RPM redline and possibly a higher top speed.
Any thoughts?
bkmagby said:Car And Driver's "Goat and Pony Showdown" January 2005, GTO vs. Mustang GT article listed the GTO as "Governor Limited" at 158 mph, and the Mustang as "Drag Limited" at 147 mph. Don't know if that is accurate or not but seams plausible given it's "Retro" design. Road & Track's "Road Test Annual 2005" July 2005, list the Mustangs top speed at 143 mph at 4500 rpm in 5th gear but doesn't indicate weather it is electronically limited or Drag limited. So who knows, but if drag is the limiting factor for the Mustang only pulling 4500 rpm in 5th gear, it stands to reason that it may pull a little better top end in 5th with 4.10 gears. Who knows, only one way to find out
