buying 4:10s

im buying 4:10s for 169 and getting installed for 200 is that a good price and i was wondering how much time it will drop off my 0-60 i have a 97 cobra w/ a tremec tko trany wiich is the main mod that i have

to pit it into perspective----I have a 2001 cobra where I had the 4:10s installed-----and labor was $800. IRS labor is so much higher because its a real bitch and pain in the ass to pull it apart compared to the solid axle.

most guys will agree that if you are keeping the stock tire size----then 4:10s will probably take 0.6sec off your time-----if you go with a larger (taller) tire----then its safe to say .4sec----definetely best bang for the buck mod. Good choice for the Cobra engine witht he 4:10s----some guys will go 4:34-----but I think for an every day driver---thats a little to steep in the gas-wallet.

That seems like a good price to me. I paid more then that when I had my 3.73's installed, only to wish I went the 4.10 route. Let us know how much you pick up.
