What front caliper does a JDM S15 spec S have?

[YVR]

are they the same as the USDM S14 calipers?
What rotor size are they? 257/22 or 280/22?

Thanks!

From what I can find, it should be 280x22mm. Calipers should be a single piston type. Not sure what the USDM S14 had (EDIT: They look like they may be the same as the Spec S). I think the caliper P/N is CL25VB

Yeah 280x22mm with a cylinder bore of 57.2mm
