Does this require the STi Spliters or can it be put on the stock WRX bumper? I have read some conflicting info on this, however most of the 04-05 wrx's that I see with the s203 lip have the STi splitters. No doubt it looks better with them anyway but just wondering will it fit without them.

 

no you need the splitters for it. at least for the ones that i have owned you do.

i have seen some where it is a two piece setup but even those i couldn't see fitting and looking right.

"For 04-05 cars, you'll need the STi splitters for a proper fit if you don't already have an STi."

 

You need the splitters. I bought mine from mastro for a little over $200.

 

cool, ordered the splitters.

 

Yup the splitters are a necessity.
