Details
Yes, 18x8.5 around +42 to +45 with a 225/40R18 tire is the conservative upgrade that two guides say works at stock height. One guide calls 18x8.5 +42 to +45 the widest size before you need coilovers. Use 56.1 mm hub rings if the wheel bore is larger, and check spoke clearance on Brembo cars.
