Im not big on the strakes by themselves. I did a whole aero kit but I suggest you check out Balrock01's ride. I took cues from him. Strakes look great with JDM mudflaps (~$100 from RRev IIRC). Also looks good with a small lip on the trunk. Just a thought of what I have seen that I like and emulate. Will be cheaper for you to do CF than it was for me to do FRP and have it corrected and painted. Let me know if I need to dig up Balrock pics.
EDIT: Its E-Tank's ride not Balrock01's.
