I picked up a JDM SI bumper today. Not the SIR one the SI one of the ZC model civic. do any of you know how id go about mounting it has the JDM bumper support, and even with my bumper support off doesn't look like a exact match. Theres a pair of second brackets on the two posts for the support should i remove those and mount it??

 

If it has the same mounts as the SiR's, just replace the JDM mounts and use longer bolts.

 

Front or rear?

 

front........

 

It should be straight forward once your USDM reinforcement is off. That can't be used no more. The factory shims may also need to be removed but not likely. You may also need to oblong the holes on the bumper brackets the get the fit you need. If you can show some pics so I can see what you are working with. Later.
