4:10s Finally installed!!!

My break-in instructions were..."no big burnouts for about 50 miles". It's been 2 1/2 years and 63K miles later and there has never been any gear related problems or noise:nice: You will enjoy them!
 
How much did it cost? Let's see......Ford Racing Girdle(rear cover) $180, 3 Quarts of Royal Purple 75w 140...$50 2 bottles of Ford racing Friction Modifier...$16 Ford Racing ring and pinion...$160 Ford Racing installation kit...$40 New Bearing...$14 Labor...$120
Total around $580

Very much worth it....Now you can feel the Stang... in the seat of the pants!:nice:

Anyone interested in swapping gears...DO NOT BUY...MOTIVE GEARS!!!! FORD RACING....ONLY!!! Friend of mine at work is having problems with his MOTIVE GEARS....WHINNING ,etc...They are JUNK!!!
 
Now I need to figure out what size tires to go with....Do Not Want them to stick out.:nono:
I'm running 285/50 on 18x10 in the back.

I'm getting the 20x9 Shelby Razors all 4 corners. Trying to decide on tires from there.
275/40 will work great. That's what Roush uses on the 18x9.

You can see the fender gap difference between our two cars. He has the Saleen springs (.25" front/1" rear) with the 275/40 on 18x9. I have StangSuspension Series II springs (1.75" front/1.5" rear) with the 255/45 on 18x8.5.

I just got a set of 275/40 for my 18x9s today and they get installed tomorrow. I had a friend's set of the same wheel/tire size on mine last week to see if they'd fit since mine is lowered 1.75" up front (I don't know anybody else with that amount of drop running that tire) and there were no issues even going over some bumps at full lock in each direction.
 
Um...

Both the automatic and manual trans cars are "5-speeds."

I really wish people would be more specific about their trans when discussing gearing.

Do you drive a stick shift, or a slush box?

:D
:lol:

9/10 when you say "i drive a 5 speed", they're refering to a stick. What if I say i'm driving a manual - I could mean a manual valve body automatic! Geez-louise
