Would love to fit one but uk laws ban them. Ideal for deer country wherw i live. Police up here have issued notices to anyone running any form of led. Side lights and marker lights included.

I have seen vehicles with two light bars and high beams around Flagstaff. From what I hear, if the highway patrol had any excuse to stop them, they would.

It doesn't seem that long ago that European headlights were illegal in 48 of the United States, excluding Oregon and Washington.

Xsit we traffic cops that clamp down with a heavy hand if you go to local court maxium penataly is appiled. No insurane means 12 ban car crushed and thousands of pounds in fines. Speeding is classified as dangerous driving which means minuim of 12 months inside. It to try and cut accidents down. Its usually a single vehicle accident well over the speed limit and death toll is very high. Came across one not pretty. Driver survived but person he hit didnot had to sit with him and phone to ambulance control. Had to describe injuries and try to keep him alive. Waited 2 hours for an ambulance to turn up. Dieing in car which has had an accident happen about once a month. Very little traffic use these roads due to low population denserty. This is way penalties are so sereve.

Looks good, but it seems like it would add to your CD and knock your MPG down by 1 or so.

For why? Stick around and you'll find out about stagnation point and the beneficial effects of an upper grille block.

My [notional] money's on the mileage goes up.

"The results aren't entirely humbuggy: They found that a wreath on the grille doesn't cost you (unless the greenery is so extravagant that it blocks cooling air for the engine)."

I think and impact will be minimal. Once I get it aimed I think I’m going to pack foam under the bar to create a less textured front end. Not sure if trapping can happen under the bar as it approaches the blocked upper grill. Plus the plate attaches behind the grill and there is now a small crack between grill and bumper that is leaking air (I assume) and will need sealing of some sort.

You're probably placing it where it will do the least harm.
It's a full-separation structure,but the cars nose will be training behind its wake.Since the area around it is in the best pressure gradient on the car,the separation will be limited to only very close to the unit.
Walter Korff and Sighard Hoerner published Cds for shapes like this,but I don't have that with me here.
