but I noticed a little drop somedays on the Top Speed once I've had installed the Jspec front facia on my own car though. I don't know if It could be one of the reasons but with the Jspec front facia installed there is more air entering into the front and both sides of the bumper and the air can not escape from there as much as before. This bumper has less aerodynamical properties than my older OEM unit with the Stillen front lip mounted on It of course but It's probably one of the best among all others on the market for the cooling efficiency of your engine/intercoolers. What's the conclusion then....make your own mind on these but my car still have a terminal clock velocity over 160mph so who cares about that....LOL
Entering a show...you can't speed but you have greater chance to win a prize if your car looks good!!!
