For your records... I have put my stock wheels back on as I am going to get the Dymags refurbished. The rears have a lot of flaking lacquer and look a mess. What is interesting is the rears have obviously got a lot hotter than the fronts due to the TC/PSM action
I weighed them with tyres as follows:
Stock wheels:
8.5X19 235/35 MPSC NO = 19kg
12X19 325/30 MPSC NO = 27kg
Dymag magnalium:
9X19 245/35 MPSC N1+ = 16kg
12X19 325/30 MPSC+ N1 = 21.5kg
So in summary 17kg unsprung weight saving with bigger front wheel/tyre combo....
Just another somewhat worring note which someone more "hands on" may answer for me:
The rear hubs have 5mm shim/spacers which are attached by two small bolts. On one side the bolt thread behind the bolt holes had shifted so the bolts could not be screwed in !! I attached the shim without the bolts since it is secured my wheel anyway but still wonder what has actually moved and is it supposed to
