Exactly, the Si front LCA's are different than any other 92-00 Civic or 94-01 Integra. Like stated above, you might have to look into having some modified to fit. If you get someone to weld on the mounting plates strongly to your control arms, you might be able to use the Full-Race or ETD one.its gonna be tough for you since your LCA's are different than 92-00 civics. Its possible but you would need to do some welding/fabrication.
The others shown above are not bolt for your 99-00 si.
