WELL Funny you should mention it,, Sort off
I have recently received a US spec kit, and whilst they fit across the width of the car perfectly, they are however approx 1 inch deeper (the bit towards the wheels) so i am going to have to cut out an inch and rejoin using some sort of Epoxy glue.
The reason for this is all to do with US safety specs..
yea, its because we have a stupid law about having a 5mph bumper in all US cars. Meaning the bumper must withstand a 5mph crash with out any body damage, so they put a bit larger crash bar in our cars.
But, all full bumper replacement body kits will fit your car whether if its for the 300 or 200.
