3.91 gear????
I went through enough searches and I can't find anything on the gears offered by 350EVO/Z1 Performance and drag racing.
I have no doubt the gears would hold up to daily driving. How about repeated drag strip launches and powershifts? How about autocrossing or road racing? Can they handle the stress.....

I would also like to know if there has been any problems with the evo3.9 or central20 gears...thanks.

I have hundreds of 1/4 mile runs and 0-60 launches and 60 plus track days on my stock lsd and 3.9 final drive. It holds up very nicely. I was one of the first to do this mod, here's the original review from years ago. Part 1 & 2 is out there somewhere too.

The 350EVO gears are good. They were originally built for road racing. I have had them for more than a year with no problems. I hear the Cetral 20 gears are good too and they are cheaper. When 350EVO came out with theirs they were the only ones on the market.
