thats the thing the previous owner removed the sway bar completely and just left the end links hanging. so i'm trying to replace but yea I'll just go oem if they are still the same size and rum es bushingsI believe the OEM front bar for '99-'00 Civic Si is 26mm. So no, it wouldn't be over kill. You're best off leaving the front swaybar stock(or stock size) if you're looking for performance.
