Yeah, jury's still out on the side grill - kind of hoping argy will come up with something after the door handles - I really like the Z8 ones but they're so expensiveI wasn't sure. Dan put them on his the mot. I'm incorporating the clear z4 side indicators into my side grill.
My mot guy said that you need to be able to see them when standing a metre from the rear bumper so t-tony would be right as you would be able to see them flashing.
I'm still going to go down the z4 indicator route as it will also incorporate the badge on the side grill as well.
