hi. i new to this site..well here i go a drive a 99 civic si and i want to upgrade the front caliper to itr caliper and i just want to know if they are going to work fine or i have to do any modification to make then fit my car or if they fit just like oem, i want to know for sure before ill buy then, dont want to waste money on something that wont work for me..thanks

 

you will need the entire hub the caliper alone will not fit, if you buy the whole hub assembly you will have 5 lugs, you could do the entire conversion just keep in mind you'll have to convert the rears also and get new wheels good luck!

 

thanks so i wont buy it since they only selling the front calipers alone.
