Bonnet scoop off a WRX, Cossie teatray and twin-DTM tailpipes?
seriously, though, front of my 100" was modded by filling rad recess with panelling bent to same curvature as wings and a strange aluminium 18x12 slotted "tray" covering part of rad (had volvo 264/5 radiator fitted) - made it look interesting (can dig out photos for ideas)
