LS1 vs. S10 Rear Disc on 2nd Gen Firebird

[Zee]

Welcome. 1 post in two years????

I've been doing the same research. In my climate, the Blazer stuff is all rusted junk by the time those trucks make it to the yards. TX would be completely different. The LS1 stuff seems to get picked over too fast and by the time I come across one, it is partially stripped down. I am thinking I will just go with new stuff as the part prices are not too tragic on GMpartsdirect. I am leaning LS1 at this time 'cause I don't like how deep the Blazer rotor is. I doubt I am ever going to be putting 15's back on my car so size of the LS1 set up is not really a problem for me. I am planning a 13" set up for the front so I would think a 12" rear would be a better balanced set up.
