BBS E88 wheels. These are Cayman spec wheels but should also fit Boxsters. Very good condition. >$5,000 new.
Used on my 987.2 Cayman S for 3 track weekends. Cayman has been sold so they're not needed anymore.
Front Wheels: 18x9, Offset: 50mm
Rear Wheels: 18x10, Offset: 38mm
They have Bridgestone RE-71Rs mounted with a few practice laps left in them.
The vividracing site says they fit 2006-2012 Caymans and Boxsters.
