Hey there just wondering i was looking at rear diffuser for my 06 ralliart and it says it will only fit if you have a evo 8 or 9 jdm bumper and i was wondering if i got a jdm bumper would it be perfect fitting or would it have to be messed around with? will it work? thanks

 

It will be too wide. The end result will also not be able to fit the diffuser properly. An undertray style?

 

so i would have to force it to fit bascially?

 

cut it down the center and take out the extrafrom each side and fiberglass it back it will be under the car so you wont really see the split.
