Customs and import taxes note.

Buyers are responsible for any customs and import taxes (VAT) that may apply but please respond immediately to all emails you will receive or the items will be returned to the UK (check those spam folders) Also, you may experience slight delays due to customs but, to be honest, things have been pretty quick once the fees have been paid.

Checkout.

I have been experiencing some problems with the shipping cost on checkout when purchasing more than 1 item, it should add 2 shipping costs as the diffusers are shipped separately in their own boxes, so please for the meantime, if you require more than 1 item, please complete with single orders, it makes no difference to the cost, just a little more time for you - which I greatly appreciate.

Please do not hesitate in contacting me with any questions - happy motoring…

Many Thanks.

Downforce

How your Diffuser works

Diffusers are essentially a raised area at the back of a car. Down-force is created when air moves quicker under the car than over it, this is why your Lotus has a flat underside and uses aluminum under trays etc. This causes the air trapped between the car and the ground to move rapidly to the rear. The diffuser section in the rear causes negative pressure at the back of the car because it has a bigger volume than the area that the air flowing into it is coming from. This negative pressure accelerates the air under the car which puts the whole underside of the car under negative air pressure. This creates a vacuum effect under the car which sucks it into the ground and creates down-force.
