it seems that in 5x100 there is an alloy option weighting 5.8 to 6.4 kgs from an audi a3, not my measure.
at first sight aerodynamics would be better than VW avus oem, i'm sorry not uploading pictures.
better ride but i thing that not very much room to great fuel saving or performance from 205/55/16 actual setup to best 195/65/15 setup. Main differences will be:
+0.4% taller gearing?
-8% rolling resistance?
-25% wheel +tyre weight?
+ a little better aerodynamics?
will all this make any difference to the following setup?
I'm planing reducing 0.6 kgs per wheel and moon caps (doomed hubcaps) instead of 7 big holes beatiful alloy wheels.
i'll test smoth hubcaps again for better assessing the aerodynamic change.
to sum up:
going from 16in 9.6 kg alloys to 16 in 9 kg steel rims but with moon discs?
improved aerodynamics plus aprox. -3.5% wheel+tyre weight saving per wheel?
