I'm about to start modifying my BMW 318iS for better aero/lower Cd..
I've read a bit about grill blocks on here, so was thinking on starting with an upper grill block:
The carr's grills are like this
Front End[/B]
Initially I'd be concentrating on the "Kidney" grills (chrome surrounded shapes with Black vertical infills).
These lead directly to the Radiator, whick is also cooled by the lower grill and a viscous fan drawing in air to the bay.
as per the project thread for this car, I'm keen to keep the mods discrete, and reversible so my initial thoughts are
1. 2 pieces of Clear Perspex cut to size and mounted BEHIND the grills-stopping through flow to the rad
or
2. 2 pieces of Clear Perspex cut to size and mounted N FRONT OF the grills-stopping through flow to the rad
or
3. Individual perspex pieces blocking the gaps between the black vertical dividers.
What would you do?
Any suggestions as to how to mount it?
Thanks!
