perf parts for the 4t60?

[grand national]

does anybody make performance parts for the 4t60E? Like:

1: convertor
2: internal parts/servos (can a corvette servo be used?)
3: shift kits that arent elec.

New to these FWD transmissions but have had many 4L60E's

There's a transgo shift kit. GM makes some higher stall converters and most of the 4T65E converters should work as well. There are some high performance clutches and bands, but I don't remember who makes them off hand.
