can a SiR bumper fit on a stock frontend?

 

It worked for me. I read everywhere that it wouldn't line up at all, but I decided to just mess around with it and see how it looked and everything lined up perfectly.
It won't work with a stock support though, you have to buy the support with the bumper.

 

Just curious - did you happen to try putting the USDM support int he JDM bumper cover?

 

if you have a hatch you have to use a 90-91 filler piece, had one on mine everyone siad it wouldn't work but it fits great. If it's a crx it should fit but the inside of headlight area will have a gap cuz the sir headlights are different

mikaela is right you need the sir support for the bumper

 

I didn't actually try it, but once I took the usdm bumper off I sat them side by side to compare and it would have never fit.
Gotta just buy the new support too.
