I was pricing this today and had one shop tell me they could do the swap and install for X amount of dollars.

I called another shop for a quote and they told me that the posi is a waste of money and just go with the gear only because the 3.8 will never spin the tires.

This is a 2000 Mustang 3.8l Coupe. CAI, UDP and 2.25 Catback true dual with MagnaFlow exhaust.

This will have Drag Radials for the track.

Who is right?

Thanks in advance!

i sure can spin my tires

if you are going to go drag racing or plan on adding a lot more power get the posi. for just daily driving as you have it it isnt NECCISSARY, but it is nice....

you will notice it most when one wheel is wet and you have more traction, or if both wheels are wet you tend to fishtail easier....

I know this is old but I have to respond. Send me the phone number to these guys so I can tell them to kiss my a$$. Seriously, what a-holes.

When I had your mods, I got t-lock and 3:73's put in my 7.5" rear end it and was a world of difference. You will be totally happy. The only thing I would do different is I should have upgraded to an 8.8" rear end instead of putting the gears in mine.
