Dude, 4.10's are fun! Traction is definatly an issue, but my car pulls hard as hell. I can't wait to put in my new spec clutch and roller rockers, and go race some new mustangs.

 

Nice! How much did your install cost ?

 

I want 4.10's. Im just wondering what to do about the speedometer being off. How did you adjust yours? I dont wanna buy a Hypertech just for that.

 

I Love my 4.10's. Still need to adjust the speedo, but I will do that once I finish my hotcam install which is amost done, and it's only been 17 hours so far! Long time, but it was my first and I am taking my time.

 

Can you feel a big difference from stock Ring and Pinion? How much was total install including price of parts? O i wouldt bother with that hypertech crap, id have ur PCM reprogrammed by PCMFORLESS, they do the job right.

 

It was $300 for install, but i also had an slp takeoff differential installed a the same time. Big difference, it pulls hard in 5th gear!!!!! I'm not really worried about the speedo, but its off at least 10mph. I'm getting the pcm burned cuz i still have the speed limiter on my car
