I have a 95 m6 and was thinking about going with 4:10's. I've never messed with any gear swaps or anything like that and was wondering exactly what I'll need to do the conversion. and opinions on the best place to get the gears. thanks.

It's not that hard.

 

Thunder Racing, Tbyrne, Summit Racing, etc. will have decent prices.

I would suggest having a trusted mechanic do the work though, I know I wouldn't be that comfortable doing that work, it's too precise- you mess one thing up and you get to take it apart again, possibly buy new gears, maybe worse...
