As a Ferrari owner and a HUGE fan of the strakes on the Testarossa and the 348, I must say, I think your car would look WAY better without the strakes. You are doing a lot, visually, with the chrome wheels and the Willwoods. I think your car would look a LOT better without the strakes.
It looks like you are trying to emulate a Ferrari by using them. And the thing is, is that you have an NSX. And a NICE one at that. You don't NEED to emulate a "cool car". You have one already.
Lose the strakes, keep it clean, and it turns into one BADA$$ NSX. Not an NSX trying to be a Ferrari.
But GREAT widebody nonetheless. Love the flow of the rear quarters on that thing. VERY clean....
