Just tried my new 4.10's at the track last night and all I can say is WOW!!! If I could ever get traction I might get a good run. I used to be able to launch from 3500rpm but now even from 1500rpm all it does is spin through first and most of the way through second gear, not to mention now I have terrible wheel hop that wasn't there before.
Even with that, I find the car drives way better on the street with the 4.10's over my old 3.55's and would not trade them back again. Now for some more mods to make the new issues go away!!

With a manual 4.10's are a perfect gear. If you do a lot of 1/4 mile stuff then go 4.30's. In an automatic 5R55 the 3.73's are about perfect. Some guys go 4.10's with the auto but with the gearing in the auto 2nd gear almost doesn't exist with 4.10's. At WOT you will only be in second gear for about 1 second. I had 3.73's in mine and went back to 3.27's with my turbos.
I can vouch for the bolded statement. I like it though. With my KDW's on a warm street the car dead hooks in 1st and rockets 1-2-3.. I can even power brake it and it will just chirp and take off. It's the fastest 320-330 bhp I have ever "felt".. that's for sure. I give all the credit to 4.10s.
When it's cold outside and I go WOT it in drive, it will (sometimes) hook first, then spin 2nd and shift into 3rd immediately, catch traction and downshift back to 2nd.. it's humorous.
Manually shifting though, it's a blast. I have a video somewhere of me hooking in 1st and when I hit 2nd smoke pours from the rears
