Default What gains in et when going from 3.42s to 4.10s?

I tried searching for the answer to this question because I'm sure it was probably posted here before but I couldn't find a post. I'm considering going to 4.10s from my current 3.42s but am wondering if it is worth the hassle. What gains can I expect to see in the quarter, if any, and what affect will this have on mileage? A friend was saying to expect between .2-.3 and possibly a couple mph. Is this true?

expect .2 but possibly as much as .4 reduction in ET... Also plus 1 or 2 MPH traps. Traction permitting. The fun factor is incredible however.

I love mine. They are really fun on the street also. Nothing like giving people a ride in a 400+ hp car with 4.11's from a 1st gear roll

Way back when I had an M6 car I did the 4.10 gear swap to it and I still say it was one of the best mods I ever did to the car. I also picked up around .3 in the 1/4 with them.
