Front splitter pics?
Discussion
Several older threads about the splitter, some with original pics, one posting even provided the dimensions.
My car came without splitter, so I had one fitted a few weeks ago mainly because I don't want the bonnet to pop open on the autobahn. I'm happy that it did the trick, bonnet stays shut with no movement at all up to 160 mph. Car "feels" a bit more stable too. According to the bible the splitter is also meant to improve the airflow through the rad, resulting in a 5 deg drop of coolant temp. While this might be true in hot weather, I didn't notice any change at present outside temps.

I did mine exactly as described in this thread:

Right, here is a pic, I hope!

The spoiler is 3" wide of which 2" is the angled down bit, the other 1" is the bit fixed to the bottom of the body. The gap between the body and the front (lowest point) of the spoiler is 3/4" I didn't measure the length of it but a look at the photo should enable anyone to figure this out
PS I have no idea why the pic is tinted blue

If i was going to fit one i would have fitted one opposite to the picture
Actually there was some debate about that some time ago, owners reported the splitter fitted facing the opposite direction, which might help in reducing the risk of damage from obstacles. The standard arrangement, however, seems to be the one shown in the picture. stefan1200 said:

To help push the air under the car I'm guessing?I'm no expert on aerodynamics, so don't know which way around would work best?
My understanding is that it creates an area of lower pressure behind the splitter which directs the airflow coming through the rad down to the underside of the car, thus preventing pressure buildup under the bonnet. Works perfectly on my car, others haven't seen any change with or without splitter so left them off.

that looks great, what is the splitter off mate ?http://www.sc-power.co.uk/SC%20Power%20Aerodynamic...
These produce a front & rear splitter for the griff - if thats your sort of thing, I imagine it will fit on to a chim.

The splitter creates a low pressure area under the car, down into which the car is 'sucked'. This also assists cooling. A hard concept to convey sometimes. It helps if you can imagine the smooth flowing air passing under the car suddenly getting 'stretched' as it encounters the splitter. And as the air gets stretched (and consequently 'thinner' or less dense) a vacum is created which looks for more air to suck into itself. It finds it in the air belting out of the bottom of engine compartment and obviously as that air is now sucked out of the bottom of the car of course this in turn 'sucks' more fresh air in through the front (or 'allows' more in).
Contrary to what's been suggested, it matters HUGELY which way round the splitter is mounted! Mount it the other way round with the edge trailing in the airflow rather than cutting into it, and it will perform a remarkable imitation of an aircraft flap trailing behind the wing with a similar angle. Great for generating extra LIFT at take-off!!
Phew - who was it that asked for a physics lesson this afternoon. :
If anyone's stil reading this far down you must be interested so there's more splitter stuff here http://www.pistonheads.co.uk/gassing/topic.asp?h=0...

The splitter reduces the amount of air getting under the car and thereby reduces lift. The slope under the front number plate causes air to pressurise when driving at speed. That air gets under the car and creates lift. The splitter interrupts this flow of air and pushes it to the sides of the car and therefore reduces under car air pressure.
No, the splitter doesn't REDUCE the amount of air getting under the car.Edited by tvrbob on Tuesday 15th April 16:10
