Has anyone put newer 20” Cayman GTS wheels on a 987.1.

From one listing I see on eBay it indicates offsets of ET57 / ET45, which seems compatible with the 987.1 offsets of ET57 / ET46. So it appears that it is possible that they may fit. But don't rely on just my word!

The offset is only one part of the story, and you can't judge the total fitment without knowing the widths of the GTS wheels as well.

Most 987 S came with 18" or 19" wheels in widths or 8.0" on front, 9.0" on rear. The CR came with 19" in 8.5" and 10.0", so I'm going to assume that the 718 GTS wheels are at least that wide, maybe wider. If so, there may be clearance issues on the inside with the suspension.

Yes, that's why I said do not rely on just my word. My 06 BS was spec'ed with 8" front and 9.5" rear. The GTS wheels I see are 8" front and 10" rear. Bolt patterns are the same also.

They'll fit, but they look goofy ...too big
