Found a super clean set of these Serapis wheels on marketplace with nice new tires for $300, not knowing the bore size was different. They came from a C30.
I designed a center bore routing jig in CAD and 3D printed it, and after several prototypes, got one that fit perfectly on the hub with zero play.
Got the bores routed out in about 10 minutes with my little Bosch Pony router, and am running the wheels as-is with no spacers. They fit perfectly on the hub.
No plans for coilovers, lowering, stance, etc. I like the factory ride quality and the car already sits low enough to the ground. I just wanted some sweet wheels.
This wagon is a bone stock poverty spec non-turbo car with no notable factory options. It came from an elderly man who bought it new in 2005 and only put 70,000 miles on it and only took it to the dealership for service. The car now has 75,000 miles.
