The GT4RS and GT3 situation is about the same as with the M2 and the M4. The lower model gets the same engine, but they definitely turn it down in power or performance so people won't stop buying the top seller.

People often over look the fact that cayman has less developed rear suspension than 911 gt3. Essentially it’s 911 front suspension on that is used on rear end of the Cayman in many ways ….. as opposed to 911 rear multi link that just works better than Caymans. People think it’s hp - I’d argue the cayman is less able to get power down on corner exit than superior 911 .
