i want 410's or 11's once i regear mine

 

that's nice i made one too to be able to compare different rear gears. its not as nice with the graph and all but it works.

 

Here's the calculator I made real quick to pick my gears. This shows F-body T56 with 4.56's and 31.22" tall tires. 4.11's with 29" tires is virtually the same but a little taller across the board.

 

I am running 3.42 with an ls t56 and a 27 inch tall tire

 

alright guys I purchased 4.11 and hope to swap these out over the holidays. Also stuck in a Spec level 3 plus. gonna see how it works.

 

I'm using the 3+ also. It has good street manners for a clutch rated so high in torque capability, except it grabs right at the end of the engagement when taking off from a stop. I heard it's normal on tech, but it's really annoying. The balance weight also came off but it seems to be working okay without it.
