The bolt pattern on the 2013 Honda Civic Si is a 5-lug setup on a 114.3 mm bolt circle (commonly written as 5x114.3 or 5x4.5 inches).
In practical terms, this means wheels must have five studs arranged on a 114.3 mm circle to mount on the car. The Civic Si (from the ninth-generation Civic lineup) shares this pattern with many other Honda models, so a wide range of wheels from OEM and aftermarket sources can fit, provided they also meet the correct center bore, offset, and brake clearance requirements.
