Hi,
I run Focus ST 170 wheels on my Puma, as most of you have deduced the spare will not fit in the standard spare wheel space under the car. As a result I carry the spare in the boot, so there is no point lugging round the weight of the steel spare and the tray. Now in the interests of weight and drag etc, a lot of time and design goes into the aerodynamics of a car regarding noise and fuel efficiency. From now on in I admit I know very little about the impact of aerodynamic drag under the Puma. So I imaging there must be some impact on drag by removing the tray and leaving a large void where the wheel and tray would have been. Well now I will open the debate, has any one got any views or experience of drag and its effects under the car. I know about ground effect on F1 cars having watched the program about the early 70's Lotus F1 cars and the discovery of ground effect.
Regards,
Richard.
