I struggle with the concept but it must be to do with the reduced speed of the air directly behind the splitte,, similar to an aeroplane wing. In this case causing suction down or it's simply to encourage a rush of air into the engine bay rather than an aero advantage.
I've ran mine with and without for months so when putting one back on I felt it gripped and stuck better on the fronts above about 70 mph,
I got some funky house guttering, black one the side you'd see from the front of the car,, yet white if you look from underneath,,,, like the chassis
Now I know that matters very little in the quest to get the speed but heck I like it
2.5 metres for a few quid, I have spares
Bit of mastic and a few screws,,,,, oupps wrong person
the plastic breaks rather than the lot getting ripped out,,, it's really the way to go.

The splitter splits the air flow to control the amount of air going under the car and around the sides/over the top.
Racing cars typically want as little air going underneath and lots of extraction at the rear to suck air out producing a low pressure area under the car and the principle applies to road cars too.
With the rounded lower edge of the Chim front air tends to be pushed under the car and this can produce lift making the front light at speed. The splitter helps reduce the amount of air going under the car and thus improve down force.

All makes sense.Racing cars typically want as little air going underneath and lots of extraction at the rear to suck air out producing a low pressure area under the car and the principle applies to road cars too.
With the rounded lower edge of the Chim front air tends to be pushed under the car and this can produce lift making the front light at speed. The splitter helps reduce the amount of air going under the car and thus improve down force.
So the deeper the splitter i.e.closer to the ground the more stable you'll be at higher speeds? Without it dragging along the ground.
Would there be any advantage to it being curved to help air escape either side as opposed to straight?

One of the best mods I did on a previous chimaera was sound deadening, made the car feel more solidly made which inspired more confidence.
One or two guys on here are in the process of putting in some heat/sound proofing.I've just changed tyre's and it's had a marked effect on the cars manners and I don't feel every electrical component shaking over bumps anywhere near as much which is a god send
I'm leaning towards this idea too

The car is roar, I like that but maybe just take out some needless resonance so I can hear the exhausts EVEN better
