gears??
 

what size gears do a 99 GT have stock?

Size? There the 3.27 ratio in the ole tried and true Ford 8.8 inch.

Personally I think they should come with 4.10's! http://www.mustangworks.com/interact...rd/biggrin.gif

------------------
00 GT, K&N, MAC Tree Killer, Pullies, 4.10’s, 2 chamber Flowmasters, UPR shifter, Weld Pro Stars, Nitto DR’s 13.35@100.02 (1.88 60ft)MM#100
88 LX coupe X-FHP, 12pt Cage, UPR K-member, 31 spline rear, full spool, more to come

Do gears increase hp and/or tqr? I'm not sure since I've never messed with my gears at all. I have a 2000 Gt.

No HP gain, it just gets you into your powerband faster.

Both are slow but easy on the eyes!

It gets you into your powerband faster, but it also increases the torque multiplication. If you go with a higher (nomally) gear, then you will probably lose a few ponies on the dyno, but you will pick a few tenths, and a few mph on the strip or street, which is what really matters.

My 3.73s are PERRRRFECT!
