I like them. My car had 4:10's in it when I bought it and with 27" tall tires it was really screaming much above 60. I debated on going with 3:55's or 3:73's but I'm too power hungry:snakeman: and went with the 3:73's cause I was afraid I'd loose too much going down to 3:55's. I am glad now I went with the 3:73's. They dropped the 60 mph rpm by 400+ rpm's which is pretty darn good cause now at 60mph it's under 3000. It did loose some on takeoff as could be expected but I believe on street tires it's just as quick cause they don't hook real well and the usefulness of the lower gear is lost time in spinning.
