Most people just gain a tow home from the track with the swap.

2 broken 10 bolts. Save money for a good rear end.

4.10's are so fun they are dangerous!! seriously, you will break stuff. become drinking buddies with your local tow truck driver/ or friend with a trailer
RPM's @ 70 is about 2400...

I gained a little bit on my 60' but lost some on the top end. Oh, and I bent an axle with it too. I'm going back to a 3.73 this winter.

Gear were the very first mod I did to my car when I got it, before I even put an intake on it.

Bone stock I went 14.0 (forgot my trap speed, though I'm pretty sure it was 101)

After the gears I went 13.7 at 103

Both runs were on the same set of crappy all season Kumho tires.

Everyone who says its going to break. Even with a bolt on LT1? I thought that was just for built engines? Because i beat on my stock 3:42 alot

Something will eventually break... My 4.10s were amazing for the first 15 months that i owned the car. About 35 hard launches at the track, and countless on the street. I eventually destroyed the pinion and the torsen's invex gear train.

Sure this is a lil off the OP question, but i loved the 4.10s so much i decided to ignore everyones advice and rebuild the 10 bolt, only with 4.11s lol I say try them, it's really cheap enough anyways

What gear is that in?

^ yeah, seriously it shouldn't be that high, I don't see how it would jump up almost 1000rpms from 3.42's

I had 4.10's in my old '97 Z28. M6 car. Only mods were Moroso CAI, Borla cat-back and 4.10's. I blew up my rear twice launching on the street!!!

as for the 2400@70...I was shooting from memory, i could be wrong

I'm still well under 2K @ 70 in 6th. I'd have to check to see exactly. I'm near 1500 rpm at 60

Is that with street tires or sticky dr's or slicks? I want 4.10's in my M6 because right now I shift into 4th gear right before the end of the 1/4 mile with my new cam, so I figured the gear would help me pull well through fourth before the end of the strip, but I only plan on running street tires. I'll never put sticky tires on my car with the stock rear end. I'm sure with a decent launch and no spinning I could trap a couple mph higher as well as take a couple tenths off my time.
