thankyou for the replies
i put a board under the car, side skirts and an air dam at the front
the car now uses 105 amps to maintain 80kph instead of 110 but i also checked the tyre pressure and they were all down a few psi so it might have come from that
ill be making the wheel skirts soon and i wanted to know what u guys think,
what i could do to get the greatest benefit? boat tail? spoiler? lift the bonnet up a bit?
