Yeah, it's fine on the drive....if someone wants it, they're welcome to it!
Interestingly, I weighed the new wheels before the tyres went on and have just weighed the old wheels (again, without tyres as these had to be removed to get to the pressure sensors off). The specs are as follows which is not the same weight saving that Maserati claim (I think they claimed something like 15kg across all four wheels). However, one aspect of the drive that is good is the ride which is noticeably better - not sure whether this is down to the nominal 4kg saving across all four wheels or because the tyres are now marginally higher in profile (and I mean marginally....they're new for a start and they also a 35 profile tyre of a 10mm wider tyre meaning a 3.5mm bigger sidewall)
Front
Old 13.8kg
New 13.0kg
Offset on both et52
Rear
Old 16.0kg
New 14.8kg
Offset on both et37.5
As the offsets are the same, I assume this does mean that all the extra 1" width is all on the outer side of the hub? Please correct me if I'm wrong there!
