Good thred! I'm goin from 4.8 to 5.3 and was thinkin to do the same thing since motor gona be out. I've got a 2000 ecsb 4x4 and was woundering about wich clutch to go to? mines almost spent @ 230,000 km's (Canadians... lol)

 

i have an RST similar to yours sir, mine has more mods though, but i recommend SPEC... i know alot of the LS1Tech guys prolly dont recommend them, but ive had mine for quite some time, and its given me no problems what-so-ever. I have the Stage 3+ and it drives BETTER than the factory one... the clutch pedal actually got easier to push down, and once its broken in pretty good/you get a little used to it, it daily drives like stock.
