I have a 95SC 5 speed. I was thinking about a ring and pinion change and was wondering if anyone had suggestions. I was thinking about 3.73's and wanted to know if they were to steep for daily driving. Also if you have done this swap, what do I need to look for specifically i.e. splines etc. Will mustang gears work?

I get about 250 miles per fill up I guess if I push it on Empty I might get 260-270 miles with 4.10's.
It used to be 300 miles. I love the gearing but you do need a Drive shaft and converter change to handle the RPM's on the freeway.Thats if you go past 80mph!

My Pumpkin is from a 99 cobra because you need the 28 spline count that is found on the 99 cobra.

Not all (like mine) were TL.
Well I'm still half right:tongue:

I thought you could go as high as 3.55 with a 5 speed?
It depends on the gear ratios in the trans and where your shifting, anything higher than 3.27 makes first gear effectively useless in an M5R2 on an SC.

I have 3.55's in my '95 SC now, but that only because I drag race it. IMHO the best gear choice for the street in a stock/mildly modified '94 or '95 SC is 3.27's. Due to the different transmission ratios, 3.08's are a better choice for the '89 to '93 SC's.

And I've tried 2.73's, 3.08's, 3.27's, and now 3.55's over the years.

it's because the 4.6 is a dog in the low end+the gear ratio's in the 5 speed's first gear is really low.
then you add the blower there is no need for any steeper than the stock or 3:27 IN THE 5SPD

For the SC.

AOD: 3.55 or 3.73
M5R2: 3.27 max

I've heard stories about how the 3.08 gears yield a nice balance between torque improvements and reducing the effectiveness of 1st gear.

I aim to try this as soon as I can find a source for the gears.

I had 3.27's in my 90 SC 5 speed and it was sweet! The guy I bought my 3.73 gears from for my Auto had it in his 5 speed and actually lost ET in the 1/4 mile over the 3.27's he had becuase the gears were to short and he had an extra shift before he crossed the line.

Listen to Niebert. Anything more than 3.27's and first gear is useless. This is a 3.8SC stick fella's, not a 4.6 auto....
