When I picked up the old 1.8 engine on the wreckers I also bought some super cheap Mazda 6 2.3 17" wheels.
The 16" OEM wheels will not clear the new brakes and I need an extra set of OEM-like wheels for inspections, longer trips etc.
I was originally looking for OEM RX8 18" or NC 17" but that's like hunting for unicorns here in Norway.
Here they are on the left.
Mazda 6 215/45R17 19.4 Kg
NC 205/50R16 15.5 kg
Enkei RPF1 235/40R17 17 kg
The spokes add up I guess. The 9" RPF1 really is the better bang for the buck for NC wheels imho.
But go 17x9 ET45 , not the ET35 like I did which requires a lot of fender roll and limits tire size to 235.
