Nice work on the radiator shroud Mike.
I am planning the same when the car comes back from trimming.
Whilst doing my engine run up last week and cleaning
oil after a little splash, the cloth in my hand was sucked against the outside face of the radiator with some force.
So am happy I've already got some good flow but as has been said sealing off the gaps can only improve the cooling efficiency.
Keep at it mate you'll be able to join in on the 2016 Alpine run.
I've logged our EOI - woo hoo!
Cheers
Steve
