if the dove tail spoiler will give us more down force on the rear axle, will it increase the drag coefficient (cw)? and reduce top speed?  |
The octane rating is not the same in europe and the states...
In Europe you have RON diplayed and over here it's the AKI which is roughly 4 to 5 points lower... therefore a US 93 is roughly equivalent to a european 97-98
