please help identify what i just bought
so after doing a little bit of research over the past week i decided it would be a good idea to do an LS1 brake upgrade on an 88GTA.
i found a set on craigslist and went and picked them up tonight and after getting them home and inspecting them i noticed they dont look like ls1 calipers at all...
from the info i have so far they seem to be 1LE calipers and brackets and who knows what rotors

IMO, No. The J55 C4 brakes are pretty good, 13" rotors, 1.1 wide. Wider calipers. These...mwah...
